Electromagnetically controlled permanent-magnet magnetic power machine

Abstract

The invention discloses an electromagnetically controlled permanent-magnet magnetic power machine, which comprises a rotor and a stator. On one of the stator and the rotor, a plurality of first permanent magnets are arranged at equal intervals in the circumferential direction. On the other one of the stator and the rotor, at least one magnetic body is arranged in the circumferential direction. The magnetic body is provided with magnetic poles opposite to the magnetic poles of the first permanent magnets. The magnetic body is composed of second permanent magnets and an electromagnet. The electromagnet is positioned between the first permanent magnets and the second permanent magnets. The electromagnet is provided with an electromagnetic coil and an iron core. The iron core is connected with a magnetic pole at one ends of the second permanent magnets. The magnetic poles of the first permanent magnets and the second permanent magnets, which are opposite to each other, are the same in polarity. At different moments, the electromagnet is electrified in positive and negative directions and the rotor outputs a torque. At the cost of a small amount of electric energy input for the permanent-magnet magnetic power machine, the conversion between the magnetic energy and the mechanical energy is realized based on the magnetic energy of the permanent magnets of the stator and the rotor. Meanwhile, the utilization rate of the magnetic energy is high.
