In one layout, the motor has an ordinary induction motor stator. A squirrel-cage rotor connected to the output shaft rotates within the stator at slightly less than the rotating field from the stator. Within the squirrel-cage rotor is a freely rotating permanent magnet rotor, which is locked in with rotating field from the stator. The effect of the inner rotor is to reenforce the field from the stator. |

ADual-rotor permanent magnet induction motor (DRPMIM) is an induction motor having a rotor inside the stator with a second rotor on the outside of the stator. This rotor arrangement can increase power density and efficiency and reduce cogging torque.[1][2]

A squirrel-cage rotor connected to the output shaft rotates within the stator at slightly less than the rotating field from the stator. Within the squirrel-cage rotor is a freely rotating permanent magnet rotor, which is locked in with rotating field from the stator.
