As Lee said, no!
Why is the commutator is hooked in series all
around the bars, not individual coils, so you would
short out if you tried to hook them in series. I

No; it just means you have a 4-pole motor.

Lol, I think you might tweak a few EVers with this John but sadly you are
probably closer to right than wrong. Market forces are what dictates the
mass mind. And frankly the bulk of the people out there are dumb as turkeys.
They will stand in the rain looking up until they drown. Or someone comes
along and knocks them in the head and smokes/barbecues them. It will take
soccer moms etc having to decide whether to fill the SUV up with gas or buy
groceries before something really happens. Then it will be a shitstorm and
probably too late. But unfortunately I am the kind of person that never
learned to sit down, shut up and ignore what I couldnt change until I was
bloodied up from at least trying. I not only fight I got thrown OUT of city
hall (actually the Dept of Revenue) last time I was arguing with the fine
State of AZ over the Alt Fuel fiasco. And no it did absolutely no good but I
can still respect the face I shave in the morning.
BTW, I am a staunch BBQ fan. I leave the granola to the chickens.

Chip hit the nail right on the head.
We are being mocked in Arizona. First by the police detaining Chelsea.
Now this little dig at the event.
You're being mocked all over the country. It's really a pretty sad
joke to the rest of us.
Example: the only coverage in this area was in the Page 2 section of
the paper that I call "Stars Behaving Badly". You know, where they
report on who is screwing whom in Hollywood and what rap star was
arrested for what crime in the last 24 hours.
The blurb was about a BoobWatch, er, BayWatch "all silicone all the
time" star being arrested for blocking a truck at a GM facility during
a "save the EV1" demonstration. (average reader: WTF is an EV1?)
Having tossed the TV several years ago I didn't know who Chelsea was
until I saw that article. Now I do. Only because I am involved with
EVs did I know what kind of fruitcake cause the demonstration was
about.
What I continue to wonder about is this. If there is this huge demand
out there for production EVs then why isn't someone building them?
No, not the Big Guys. Tuner shops like Rousch and Saleen and
Lingenfelter who take production vehicles and turn them into hotrods.
Why aren't there shops that have selected a model to specialize in
(like the Saleen Mustang), designed and built an OEM-quality EV
drivetrain and put 'em on the market? There are plenty of rich folks
out there who want to look green who would fund such a startup if
there was a business case to be made. If you offer the appropriate
product then the Big Guys will sell your product. Just like you can
buy a Saleen Mustang from a Ford dealer.
That's the key, I think. There IS NO DEMAND, at least none that
matters commercially. A few hundred True Believers do not a market
make. When someone makes the case for there being a market using
generally accepted methods for the industry (NOT internet petitions or
email bombings or phone trees or....) then the money will be
forthcoming.
I don't see this as being a whole lot different than my BBQ
restaurant. I love BBQ, could eat it 3 meals a day and don't quite
understand why everyone else doesn't. Yet my sober side believes the
National Restaurant Association statistics that say that only about 2%
of the meal parts go to BBQ joints. I could believe with all my heart
in my product and the demand I think should be out there but if I
planned my business accordingly I'd go bust.
If pure EVs ever have a chance (and I don't think they do) then the
advocates are going to have to stop acting like nutcakes and start
selling the product on it real merits. No gas stations, no gas fumes,
no engine, cheaper operation. The environmental claims either trigger
a yawn or the person's lie detector, depending on how much he
understands how electricity is generated and distributed. In the real
world and not some fanciful never-never land.
Brands and segments tend to develop stereotype public images. I got
rid of my gorgeous 635CSi simply because I got tired of being
classified with all the yuppie assholes who now drive BMWs. Or think
what pops to mind when you hear "SUV". Does the same thing happen
when you hear "Pickup Truck"? Essentially the same vehicles.
Buick and Pontiac lost the fight to change their images as brands for
geezers. Similarly, the image of an EV driver is that of a fruity left
coast granola eating tree hugging nutcake. I don't know how many
times I've gotten a variation of the theme "I KNOW you're not an
enviro-whacko so why the EV?"
Answer: because it's fun, it's cheap to operate, I don't have to deal
with the high school dropouts at the gas stations, I refuel at home
and it fits my around town transportation needs better than my regular
cars. THESE are the selling points that will win people over. No
enviro-bleating necessary.
That is going to be a very difficult image to overcome. Silly stuff
like this sit-in only make things worse. I suspect that one of the
main reasons hybrids are doing so well right now is precisely because
they had no public image attached going in.
Something for you True Believers to think about as you munch on your
granola bars....

Now yur talking! Been following Jerry's thread on building up bodies,
etc. OK Build a Sunrise body? OK NOW where do we go. What running gear,
suspension, brakes, tires, all the little stuff that makes that pretty body
a CAR. Hate to sound knit picky, but it was these details that sunk Citi
Car. The damn windows and doors HAVE to work! Seats hafta be adjustable so I
can get my 280 lb 6'4"ass in, or Rick Pryer can slide it forward so HE can
reach the pedals<g>!Seats? Yeah, where do ya get them? Glass, window
mechanicals? the damn windows HAVE to roll up and down or a motorized thing.
Can you BUY this stuff, from small builders of parts? Steering wheel,
column, light controls Wipers, heater, AC system, all that stuff that comes
with a clean doner car.Wayland can do the Sound System, no problemo!
I don't think Solectria EVer Crash Tested the car. Seth, correct me on
thi$ one? If we could overcome these details, lottsa empty industrial bldgs
in CT just down the road from Solectria and RI. CT is looking for start up
stuff like this. Cars WERE built in CT 100 years ago, Pope Electrics in
Hartford, Losiers in Bridgeport, a few others I'm sure.
Jerry? Yes, lets talk about your Lumbergini. No, seriously, can we build
some with a bit of cash up front?? As somebody ELSE sed, let's put our money
where our mouths are. A thousand Listers here? We could pony up a startup
fund for Jerry. Order 5 or 10 I think a woodie scares folks away, UNTIL they
see what Jerry has in mind?Gotta be cheaper than the Tango Startup? Were not
as fancy as Tango. If ya want a Radio you go out and BUY one,just build a
turnkey CAR, or buy it in a semi built kit. Can ya offer it from kit to
turnkey?Depending on how much money and time a guy haz?
I'm not crazy about 3 wheelers, but look at all the un happy folks that
put up BIG bux for the Sparrow. A really useless car for MOST of us. Hell,
you can't bring home 200 bux worth of groceries or a load of studs from Home
Despot!They are cute, a tiny start up thing to get a poz cash flow, THEN
we'll go for full size take-the-kids-out-for-Pizza Mom-Mobile, Sunrise. The
Lumbergini would be just the ticket for the legions of Train Commuters here
in the Big East! People buy a older car as a " Train Car" it's sole purpose
in life is to get the guy, or gal to the train and home again. In Boston NYC
Philly, Baltimore ,Wash DC people TRAIN to work. Hugh parking lots chock
FULL of cars by 8am. Lumberginias would be easy to park! This would endere
them to the commuter guyz! In that you often can't EVen FIND a parking spot
among the bememoths at the station.
OK I'll stop now. Just like to run those thoughts by the List.

I know of this one but he is in the west, 2000 miles away. I havnt timed
it to 100ks/hr. Has 9" motor & 1200A controller. Batteries are the
pansonic type. 33Ahrs each 3 strings in parallel. I don't much like
paralleled groups so when these die I will try & use only one string of
something. You are right about the P drivers. If I had my way they would
start off with rubber band powered vehicles.

I've always been curious how fast it went. I almost assumed
this was your car, until I noticed the batteries it used
weren't 100 ah like yours.
What will yours hit 100 km/h from a start in? Timed it yet?
What type of batteries you have in it? Motor, controller?
I heard of recent legislation in Australia where all
'provision drivers', being aged 18-21, are banned from
operating V8 powered cars, supercharged cars, and
turbocharged cars due to escalating road deaths and an
attempt to crack down on street racing. The EV is one very
crafty loophole around this, letting the youth have an
overpowered car that they can race.
I'm an American, however, so this legislation could be a
myth of sorts.

A few have, in fact. Also aside from the TdS X1/9:
http://www.austinev.org/evalbum/040.html
http://www.geocities.com/villahelena/ev.html
IMO, the Toyota MR2 made a much better X-1/9 than Fiat's
X-1/9, if that says anything. I shirked this design in favor
of a much lighter car with similar GVWR and ok battery room,
a Triumph GT6. 2,350 GVWR, 1,793 pound weight.
A Fiat 850 Spyder looks like it would make an excellent EV
as well.
The Cd of the X-1/9 was .38 according to the following:
http://www.teknett.com/pwp/drmayf/fiat.htm
Look here for more info on other cars:
http://www.teknett.com/pwp/drmayf/tbls.htm
The one in the Tour del Sol supposedly had a Cd of .30. That
sounds about right for a reduction you could make, but it
had a front air dam and extensive modification.

I recall it being 130 miles per charge. My guess is that
this was at about 40-45 miles per hour in good weather?
The real figure I'm interested in is 65-70 MPH cruising.

Hi Everyone,
I've been anticipating warmer temperatures to time the 200sx's 0-60. I
decided tonight was the night. One of the problems around where I live
is that within a close distance to home, there aren't any roads that
have a 55+ mph speed limit. I really can't afford a ticket. But...I
figure if I'm careful, I can time it without getting in trouble. By the
time I got to the road of choice, I had put about 1.5 miles on the car.
Keep in mind it has a range of 5-10 miles. I wanted to do the timing
with as much of a full charge as possible. The road I chose actually
wasn't a very good choice. I was nearing a curve by the time I hit
56-57mph, so I hit the brakes. My stopwatch said 11.79 seconds. I was
close to my work, so I went and plugged in (my work has allowed me to
plug in there - which is very nice!). I decided I choose a different
road and try again after it filled up.
I did a few things at work, and by the time I came out, the roads were
wet from a drizzle. It has pretty much stopped, so I decided to head
out and try anyways. I headed to my new speedway and got lined up ready
to go. Punch the pedal and hit the stopwatch button...only to spin the
tires in second gear on the moist pavement. Uggg. Well, I guess I'll
try it another day. I'm encouraged by the first timing. I don't know
how long it will take to creep from 57mph to 60...maybe 1s? I'm
guessing that by launching harder, knocking my Zilla low voltage setting
down another few, and coming out with a full charge, I can do better
too. I have written down as my guess 12.5 seconds. I think that will
be pretty close.
Is 0-60 the most common measuring point for vehicle performance? What
about 0-30? 0-40? I'd bet that the 0-30 time of the 200sx beats the
average car. It really pulls as it's taking off. I'm planning on
"racing" a friend who claims his new Jeep Cherokee will do 0-60 in 8
seconds. I just want to see how I fare from the stoplight to the other
side of the intersection. :)

Well, first of all it's not "one" vehicle. The vehicle has to be crash
tested from the front, the rear, the side, etc. EACH test has to start
with a complete, brand new, undamaged vehicle.
So you have the expensive of several vehicles (I don't kow the exact
number), then you have to pay for the testing, the cost of using the
facility, the employees wages (and these aren't McDonalds employees making
minimum wage), the consumable testing suplies, etc. Then you have to pay
to have the data analyzed, computer time, more expensive emplyee wages,
etc.
Then, as is likely, if some part of your vehicle fails to pass, you have
to redesign and start all over. ALL over, even the tests that pasted the
first time, because your changes /may/ have effected them.
Later on if you make any major changes to the vehicle, you also have to
start over from scratch.

Folks, I'm seeing a lot of personal attacks and mudslinging on the list
lately.
If someone on the list is being obnoxious, it's generally so they can get
some attention. If someone is obviously trying to get your goat, the best
response is to ignore them. If you respond, you are just doing EXACTLY
what they want you to do.
If you find that you almost never like reading what a particular person
has to say, then I would suggest that you create an email "filter".
Almost all email software allows you to create "filters" that can sort
your incoming email and automatically delete them based on sender,
subject, etc.
If enough people ignore the offender either they will change their ways or
go away, either of which is a preferable solution over wasting list
bandwidth argueing with them
Cheers, Pete.

I've heard this arguement here before, and frankly it doesn't wash.
These days many cars come with VERY long warranties, 7 to 10 years is not
uncommon. With the economy the way it is, many are also offering 0%
financing.
I just can't see the automakers selling a vehicle at cost, allowing you to
finance it for 3 or 4 years (so they don't even break even, because 4
years later they have effectively LOST money, i.e. ROI) and not expecting
to sell you any major parts for 7 to 10 years.
Nope, by that time they would have made more money using a plain old
savings account.
Besides, 7-10 years later and EV would probably need a new battery pack
and THAT would cost a lot more than a new muffler/alternator/fuel
pump/etc.

I'm looking at a Ford F-250.
if I used 40 T-145's, Z(1or2)K,
Do I really need a Z2K,
A couple of thoughts based solely on my experiences with my Jeep
Cherokee conversion:
I now have a Zilla 1K (after using a Raptor 600 for awhile) and the
Cherokee's performance now feels like it did stock (with a 6-cylinder
engine). That is good as when I had the Raptor 600 in my Jeep the
performance was borderline unacceptable. Also, I'm using flooded
batteries so I have the Zilla current limited to 400 battery amps.
So, my guess would be that a similar setup (Zilla 1K and flooded
batteries with around a 400 amp limit) would be pretty bad in an even
heavier vehicle like an F-250. Of course, with 40 batteries you could
have two parallel strings of floodeds and get more current on the
battery side. That might get you better performance out of a Zilla 1K?

Hi All,
You've probably the saying, "There's a fine line
between a visionary and a fool". Well, as gasoline
continues to climb lately, I've been taking some
solace that maybe I'm more on the visionary side, and
less of a fool. (;-p
CivicWithACord just turned 1,100 miles. Would've
put more on in the last 8 mos. I've been driving the
rig, but of course, my town is small.
I waited until Spring Break to pull the adapter
plate from the tranny to troubleshoot the noisy tranny
issue.
To review, the sound doesn't occur all of the time.
It is most common at 25-32 mph in 1st gear, generally
stops for awhile when in 2nd, and comes back at higher
RPMs. It is a rather grindy, growly type of sound.
When I stomp on the juice, it does rev up just a bit
without an accompanying acceleration as if there were
slippage somewhere. It's not too loud, but definitely
noticeable. But there can't be too much tranny
slippage, b/c I'm at 288-300 watts/mi., which is
pretty avg.
Well, after thinking that perhaps the input shaft
is rammed up too hard against the pilot
bearing/flywheel, I was able to slide in some washers,
about 3/32" in thickness between adapter plate/tranny.
Bolted it all back up and... same noises.
Next hypothesis, please...
For those of you on the gearhead end of things-- what
does a bad pilot bearing sound like? And does it look
any different than a _good_ pilot bearing?
(I _know_ when we assembled the flywheel, that the
bearing looked just fine, but perhaps appearances
don't tell the whole story. I did not spin it, take
it out, etc).
So the next plan would be to take it to my local
tranny guy, pull the controller (again), leave the
video of our assembly with him, so he knows what is
entailed, and let him check out the pilot bearing. If
that looks good, it's gotta' be the input bearing. (I
don't have tools to pop out a bearing). Sooo,
what does a bad one of _those_ sound like, and are
there other symptoms?
Your insights are gratefully appreciated.

Hmmm... having driven a Jeep Cherokee for almost four years now, I can
safely say that I would NOT want to race in one (or in a Jeep Wrangler
for that matter). They have relatively high centers of gravity and
typical Jeep steering/suspension which would scare the crap out of me at
high speeds and/or doing fast maneuvers. :-0 But maybe I'm just too
paranoid ;-)

Then, I don't understand what your BMS is doing. In my circuit, D1 is
what is regulating the voltage, and limiting the base current to Q1.
Can you provide a more complete description of exactly what the BMS
circuit is that you are trying to connect to?

You are precisely describing a 4-pole motor. You will also note that it
has 4 field poles; alternately north-south-north-south, equally spaced
around the outside.

As I said, no it cannot be reconnected for double the voltage. You can
have it REWOUND for double the voltage, though. You remove the wire,
counting the turns, and replace it with twice the turns of wire of half
the cross-sectional area.

Are you talking about generating power while underway, or for stationary
charging?
Start by studying what's been done by others. I've read about 5kw solar
Sterling generators and other examples on the order of what you're talking
about. The fact is that it's been done, and likely there're similar size
Sterling engines/gensets out there right now being produced----how much are
you willing to spend?

A 5HP steam engine isn't cheap to make ($1k min.) and $3-10k if built by
someone else.
I would wager a similar scaled Sterling would cost 2-3x this.
And at 5HP of mechanical power, you might be able to drive a generator
enough to produce up to 3kw. Oh, and you'll have to add $200-400 for a
suitable efficient generator (perhaps an ETEK?).
Meanwhile, 3kw of manufactured solar panels can be had for under $10k.
Scratch built, a solar panel can be built from bulk cells for as low as
$1/watt for the cells, plus interconnects, silver solder, encapsulation,
substrate materials and lots of elbow work---i.e. under $4k for 3kw of solar
panels.
>From a cost and time perspective, even if I had a full machine shop, I'd
probably prefer to build a solar panel from scratch than build a sterling
generator---that is, unless I really wanted to build the Sterling for other
reasons. One big reason to go Sterling over solar is if you need a mobile
generator on your EV and your EV isn't a barge boat like mine.

Is this fiberglass company busy all the time? Or do they have some
slow times with people sitting idle? Would they be willing to produce
a unibody or two and allow the payment to be made for them after they
are completed and sold? A consignment deal.
After the body is made, who were you planning on completing the rest
of the car, then who to sell it and by what means? How much is this
completed vehicle going to cost?

Hi David,
Check out our National Electric Drag Racing Association (NEDRA) site at
http://www.nedra.com for some pictures of EVs doing burnouts.
If you want to see some sparks we do have photos of the Orange Juice
Dragster shooting some sparks at last years Power of DC race
Go to http://www.powerofdc.com and link to the Photo Gallery
I tell you what, if you want to see the actual sparks photo go directly to
this picture on the Power of DC site
http://www.powerofdc.com/2004/oj_sparks_640.jpg
You will see about 5 bright sparks trailing behind Orange Juice from the
dragsters motor arcing.
This was not a good thing though, however, and the dragster was pulled into
the pits to see what was going on.
But, Sean Lawless who owns the dragster and runs Lawless Industries at
http://www.paradefloats.com will be back at our Power of DC Race June 11
with a very cool EV that will blow everyone's mind away. The dragster may
also make it again too.
Stay tuned.
Also check out MegaWatt Motorworks. Dave Stensland has some photo galleries
of recent NEDRA events. http://www.megawattmotorworks.com
So there are plenty of Drag Racing Pics to go around.

the piston is at the position he was put by the mounter man:^)
the system which return back "a little" the piston is the washer form,
there is some sort of lip on it that deform hitself when going one way and
so force to go backward (few micrometre) sufficiently to let the rotor
rotate again withoug drag when you release brake pressure.
hope my french>english explanation are something understandable :^)

With it in neutral, can you give it just enough throttle so you can
have the motor turning? Or even with the car rolling, by moving the
clutch in and out, you might be able to have an effect on the sound.
If so, I would say it's the throwout bearing. Like for example, if it
only makes noise when there is no load on it(clutch engaged), and
roars when there is a load put on it(clutch disengaged).
> It is most common at 25-32 mph in 1st gear,
Find a hill, or get it up to speed, put it in 5th gear and let the
clutch out. The tires will turn the transmission, then you can hear
if it does it in 5th gear too just for a more complete picture on the
situation.
>what does a bad pilot bearing sound like?
I don't think it's the pilot bearing making all that noise. If it's
never been replaced though, change it out while you've got the
chance($12).
The throwout bearing for my car is ~$20. I always put a new one in
anytime I replace a clutch, or I have the transmission out depending
on how many miles are on that throwout bearing. They are cheap and
wear out. I've been threw a few. Nothing worse then to have a
howling throwout bearing and be pulling the transmission just to
replace it.
If you are going to be having the motor or trans out, go ahead and
replace it. Might as well put a new clutch disc in it too for cheap
insurance. Look at the pressure plate and flywheel for cracks on the
surface caused by heat. Might consider replacing either of those
items if so.
You'll be good for a lot of miles with a brand new clutch disc and
throwout bearing installed.
FYI, I just looked on http://autozone.com/ and a throwout bearing for
a '92 Civic is $42 and a clutch disc is $49. While I'm at: Well they
don't list a flywheel. You might be able to get your stock one
resurfaced(if it needs it) at a auto parts store though for like ~$7.
If the place will "turn" brake drums and rotors, they will likely be
able to do flywheels. This place locally to me "turns" those items:
http://www.oreillyauto.com/ Pressure plate is $62.
If you had an engine hoist, you could lift that electric motor right
out of there..
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=35915
They go on sale for ~$160 or so.
Pick up one of these too:
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=42356
Let me know what it turns out too be.

Except they changed the tax laws and now (Heavy) SUVs have a limited tax

In fact we already have the way to make EV happen quickly, conversion can be
made, fast , slow, short long range, cheap or expensive, owner decide.
EValbum prove it every page BUT it depend entirely on country regulation.
In USA each people who succed converting a Infernal combustion car to EV
SHOULD become a "professor" for same town people who "want to".
In Europe we can make conversion easely but can't put them legally on the
road, period...otherwise i would have been already making this happen lots
of years ago...
I always want an electric motorbike but I'm now converting a bad designed
electric scooter to make it good only because... it's already registered as
an electric scooter.
That way it's more discrete than an ICE conversion and i will not talk the
lawyer and insurance company about the complete system modification i made.
unfortunately liying is the only way for us to drive our EV...
:^(
help each other, it's the ONLY way to have lot's of EV quickly on your roads
and so increase the demand.
