It is about 75% of stall torque. It takes more torque to start an air motor than to keep it running. Do not confuse stall and starting torques. If the air motor load exceeds its starting torque, the motor will not start.

    motor torque calculations for electric vehicle saurabh chauhan abstract: It is estimated that 25% of the total cars across the world will run on electricity by 2025. An important component that is an integral part of all electric vehicles is the motor. the amount of torque that the driving motor delivers is what plays a decisive role in switched reluctance motor is high torque ripple, mechanical vibration and acoustic noise. due to its nonlinearity and doubly salient structure torque ripple becomes inevitable. this paper discussed about the outset of torque ripple and the appropriate methods used so far to diminish the torque swell in switched reluctance motor.aug 22, 2012 induction and reversible motor speeds cannot be adjusted. this is why the motor speed must be reduced with gearheads to match the required machine speed. its therefore necessary to determine the correct gear ratio. next, calculate the required torque. In a single-phase induction motor, starting torque is always lower than the rated torque.
