The present invention relates to power and control technology field, specifically to a motor, comprising a digital motor or an asynchronous motor. 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. The motor of the present invention is featured with limiting current, controlling temperature raise, flexible transmission (starting), overload protection, high efficiency and energy saving performance; in addition, it can precisely feed back the real-time running state of load, and it is convenient to set automatic functions of motor, such as failure warning, running time, circulation time, displacement distance and rotating direction. |
