Re: Motor Quiz
Spoiler for Work:
60 oz-in (or 0.42 Nm) is about 1/6 (0.17) of stall torque for a CIM (2.43 Nm), at which a DC motor runs at about 5/6 of free speed. 3700 rpm is 0.83 (5/6) of 4473 rpm, the free speed at our mystery voltage. Free speed scales with voltage, so if a CIM's free speed is 5310 rpm at 12V, the mystery voltage is 12V*4473/5310 =


10.1 V
