I\u2019m trying to figure out the best motor for my project. I\u2019m now down to considering the EVE AC30 (or AC40) versus the DC WarP 9.<\/p>\n

The WarP 9 data is all given at 72v rated on the dyno by Netgain; I simply doubled the RPM and assume the torque output is the same up until about 4000 RPM; I\u2019m not sure if that assumption is correct.<\/p>\n

Here\u2019s a graph of Torque vs RPM for the various motors:<\/p>\n

I know the HPGC AC50 will be underpowered for what I want, but this chart makes it look like the WarP9 is also underpowered. However, this at ~260 amps \u2014 more amps will give more power, but it is a question of how long can the motor take that.<\/p>\n

UPDATE:<\/b> From http:\/\/www.belktronix.com\/WarPOwnersManual.pdf<\/a> I found out the Netgain WarP 9 is: \u201cThey are actually rated at 450 Amps for 5 minutes, 225 Amps for 1 hour, and 190 Amps continuous duty\u201d.<\/i><\/span><\/b><\/p>\n

I could probably (quite safely) push 300 amps for 10 minutes up my 5% grade hill.<\/p>\n

Based on looking at other AC conversions, I think the AC30 will be too weak; I really would need to go with the EVE AC40. I\u2019m sort of paranoid to use a motor that no one else in the US has used in a conversion.<\/p>\n
