RE: using a washing machine motor Tiny is a relative term. About 100mm squarish body, I'm comparing size to NEMA motors. The other motor pic looks very clost to the one I have here. I still have the drive card from the washer here, I'll go and retrieve it. I was figuring on using a 1 1/2hp VFD that has documentation included! Even if you work on appliances professionally, getting any documentation besides "replace module A and module B" is very difficult. My intent is to build a baby slant bed turret lathe.

I start the sim/axis/axis config, take the machine out of estop and turn it on, and home all the axes. Then i jog Z up or down to someplace, hit the End key (or click the Touch Off button) to bring up the Touch-off dialog, type in 0, and click Ok. The backplot immediately jumps so the tool is at Z=0.

No windows manager, no gedit or geany. ;-) I used to use EDLIN and COPY CON to write autoexec.bat and config.sys files, and DEBUG to low level format MFM hard drives. ;) And nostagia hits, launch a cmd prompt and enter edlin. Hmm an error message that c:\Windows\SysWOW64\edlin.exe isn't compatible with 64bit Windows. What the??? Says I should contact the vendor to see if a 64 bit version is available... Which is crazier? That Microsoft includes edlin.exe with 64bit Windows 7 Ultimate or that it's included *but cannot be used*? Edit is in there too, but also doesn't work. Tech Net says these are "not available" in 64 bit - so WTH are the program files *included* with 64 bit versions? --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------ Message: 3 Date: Fri, 19 Dec 2014 05:22:30 +0000 (UTC) From: [email protected] Subject: Re: [Emc-users] Using washing machine motor To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 Our Sears washing machine got replaced and I got the motor.

If so, I think it would make a fine spindle motor. I've only run this one with a VFD on the bench, but I can't see why it wouldn't work well. http://www.wallacecompany.com/machine_shop/wash_motor/wash_motor_side.jpg http://www.wallacecompany.com/machine_shop/wash_motor/wash_motor_plate.jpg -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------ Message: 5 Date: Fri, 19 Dec 2014 03:50:36 -0500 From: Gene Heskett <[email protected]> Subject: Re: [Emc-users] Using washing machine motor To: [email protected] Message-ID: <[email protected]> Content-Type: Text/Plain; charset="windows-1256" On Friday 19 December 2014 00:22:30 [email protected] did opine And Gene did reply: > Our Sears washing machine got replaced and I got the motor.

Or with a timing belt reduction, a milling machine or lathe spindle for up to a 8" lathe. You did not salvage the motors driving electronics? Not having the driver electronics would run the cost up a bit. IIRC I saw something on PCW's site that might work for that. Thats www.mesanet.com. Find the 8I20. Its for 3 phase stuff to 400 volts, and 30 amps. Over kill, but can do that job I would think. Probably a daughter card setup that would need another interface to the computer. I have no experience with it, so Peter, help me out here? You say its tiny, and I'd assume air cooled. How big around is it. I would love to find something I could mount in the nominally 50mm diameter Z slider castings hole for the existing spindle of my toy mill which currently has a 200 watt, nominally 4k revs peak motor that drives to 2500 revs max thru noisy, high failure rate plastic gears now. All the candidate motors on fleabay are 53mm and up diameters, and would need the spindle bore enlarged, at risk of finding air.
