Motor

摘要

A digital motor comprising a stator, an internal rotor and an external rotor; wherein the internal rotor is embedded into the external rotor, with a cavity provided between the internal and external rotors; the cavity is filled with magnetic phase-change material. The asynchronous motor comprising a rotor and a stator; the asynchronous motor adopts two groups of rotor-stator structures that are arranged coaxially; one group is a driving rotor-stator structure, including a primary stator and a primary rotor; the primary rotor is formed by embedding a primary inner rotor into a primary outer rotor, phase-change magnetic materials are filled into a cavity between the primary inner rotor and the primary outer rotor.

1. A motor, comprising a stator, an internal rotor and an external rotor, wherein the internal rotor is embedded into the external rotor, with a cavity provided between the internal and external rotors; the cavity is filled with magnetic phase-change material; the stator is provided outside of the external rotor, while the internal rotor is connected with output shaft of the motor; after switching on the power, the external rotor is driven by a rotating magnetic field generated by the stator to rotate at first, and then the internal rotor is driven by a rotating magnetic field generated by the external rotor to rotate; as a result, the motor shaft is driven to rotate and output kinetic energy, and the internal rotor generates induced electromagnetic field while rotating; the internal and external rotors automatically regulate magnetic phase and form a closed magnetic circuit, because the magnetic phase-change material is filled in the cavity between the internal and external rotors, when the motor is running after switching on the power, a flexible driving force is generated from the external rotor to the internal rotor, so as to realize flexible output of power of the motor shaft.
