An induction motor with on-rotor slip power recovery may have a rotor and a stator element. The rotor element has a rotor winding system with a number of winding units wound-distributed for inducing a rotor magnetic field. Each winding unit has an induction and an augmentation subwinding. The induction subwinding has two legs of each a number of induction conductor segments. The induction subwinding induces an emf that drives a rotor current in the rotor winding system to generate a basic induction component for the rotor magnetic field when the induction conductor segments move in the stator element. The augmentation subwinding has two legs of each a number of augmentation conductor segments aligned parallel to the induction conductor segments. The augmentation subwinding being wound that the two legs of augmentation conductor segments are immediately next to each other and positioned mid-way between the two legs of induction conductor segments.

Disclosed are a variable power motor and an intelligent controller therefor. The motor includes a rotor, a stator, a housing, stator windings and terminals. The stator windings are formed by embedding the same stator core into multiple series windings. Various series nodes of the stator windings, each serving as a power supply terminal with different power, are respectively led out individually. The various series windings of the stator respectively control, by means of the intelligent controller, the switching on and off of multiple switching switches. The soft-start and soft-stop of the motor can be realized, and a load is automatically tracked to regulate the power of the winding during operation, so as to obtain a power-saving effect.
