technical field

The invention relates to a permanent magnet generator with double stators and double rotors.

Background technique

A generator is a device that converts mechanical energy into electrical energy. It is widely used in many fields. The excitation generator commonly used in automobiles needs to supply excitation current to work, and there is excitation current loss. In addition, carbon brushes and slip rings have short service life, poor reliability and high failure rate.

In the past few decades, due to the improvement of permanent magnet material properties and power electronic devices, the energy saving and long life of permanent magnet generators have become more and more attractive. The rotor used in the automotive permanent magnet generator has no excitation winding, no excitation current loss, no carbon brush and slip ring structure, high power generation efficiency, few failures, and long service life.

The existing permanent magnet generator consists of a shell, a stator, a rotor and a control circuit. The stator is composed of a stator core and a stator winding; the rotor is composed of multiple pairs of tile-shaped permanent magnet steel sheets, permanent magnet supports, protective iron sheets, and a central shaft , bonding material layer, etc.; but with the development of automobile technology, the requirements for automobile environmental protection and energy saving are getting higher and higher, and the existing generator structure can no longer meet the needs of users.
