The torque of a three-phase induction motor is directly proportional to the product of stator flux per stator pole, rotor current, and the power factor of the rotor.
The speed of the rotating magnetic field is dependent on the applied frequency and the type and amount of magnetic material used in the motor. However, the torque produced by a three-phase induction motor is not affected by the shaft diameter.
