Remember that load = Amps. Torque = Amps DIRECTLY and the motor size has no affect on this peak value if at the same max roadspeed/gearing.
And all powerchair 4 pole motors would draw north of 300A if fed 24V. This is limited by the controllers max Amp level. So consider this when you look how many M1 and M2 Motor Amps my powerchair ON CASTERS took turning in place in my hallway.
You really need 120A just to turn a heavy rear drive powerchair on casters. This is a screenshot of my Salsa chair, 6mph gearing, 4 pole motors turning in place in my hallway. Note that its 102A and 114 Amps... If this was "tracked" it would need at least double this figure before it turned. At LEAST!
Real time monitoring via R-Net programmer and laptop. I simply turned in place in my hallway, on heavy carpet in a normal powerchair.
