The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and shortterm ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.

In order to determine the performance you'll need from the motor, there are three factors to calculate; Moment of Inertia, Torque and Speed. (Refer to the below sections on calculations for each.) Once you've calculated the inertia, torque and speed for the motor you'll select the type of motor based on the required specifications.
