What is expected in stall torque from a regular car/small tractor starter motor?
I measured 7-9 Nm on a starter motor I had lying around, and I'm not sure if this motor is crappy or if such performance is expected.
It was fed with 12V battery and parallelled with a battery booster (basically a transformer with 12V ouput). I couldn't measure the current, but the boosters 40A current indicator looked like it was going to hurl its pointer through the glass.
The reason I ask is because if it seems to have a reasonable stall torque it will propel an electric motorcycle.
