"/The Warp11's are also subject to the same 170 volts maximum. Larger motor but wound about the same I'd imagine. I've yet to have my face inside of a Warp11 though so am just going more on a hunch here. Per George Hampstra (NetGain) he stated all their motors are "able" to take "up to" 170 volts. Unless you're a racer looking for a record I strongly advise people to limit their voltages to their motors. The Warp's are advanced to 12.5 degrees vs the Advance's (FB1) at 10 degrees so I'd limit the ADC's to 160- volts or risk frying your brush rigging per my previous link. Let's look at John Wayland as an example though, when he launches White Zombie and asks the Zilla to give all it's got, his 360 volt battery pack sags to something like 160+- volts! Now, if we take the 1000 watt per HP rule (accounts for losses) and let's EVen be conservative here 1500 amps X 160 volts will get you 240HP, and if you fed that through an 11" motor the torque would probably break stuff. Anyway, as a motor guy who gets to see real world failure points, it's just not worth trying to push to many volts through your motor. Adding a little more brush advance can let it accept a bit higher voltage but it's hard on the motor and makes for unhappy motor life, so please protect your investment, or cry to me latter, and I hate to see grown man cry Cya Jim Husted Hi-Torque Electric/" -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/9-Inch-ADC-Motor-Max-Voltage-tp4673404p4673424.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
