Thanks.
It's an 11" (dia) motor from a Hyster forklift. Underwhelming stock specs are:
DC 36/48 volts
14.00 KW
RPM 1000
60 Min Duty Cycle
Class H Insulation
330 Amps
It's currently wound SepEx (separately excited armature and field), but I will be converting to series wound field coils. I'll probably swap in a set of refurbished field coils initially, but the plan is to custom wind a set for this application. It should turn 5-6K, and put out around 500hp/1000ft-lbs. The ultimate battery pack will be 330v/2070amps, and the motor will be built to make use of that. The controller is a new one coming out (currently in development) with 500v/2500amp max numbers. That battery pack is actually capable of supporting over 900hp, but I don't think my motor will be capable of that.
