The motor RPM also helps to determine the amount of power output from the motor. At zero rpm, the power output is zero and at maximum operating speed (RPM) the value of the motor's power output is at its highest. The torque or the driving force which causes a motor to run is also active from 0% to operating speed. The motor …
