Gain and application of electric energy is an important mark of human social progress, electric energy is a kind of energy form which modern society cannot leave away, whatever in any industry, electric energy can be applied inclusively. The most normal form of electric energy application is transform electric energy into machine energy, transformation mean is application of electric motor. Quality of electric motor transforming into machine energy is relate to whether electric energy can be utilized fully, and relate to driven device efficiency and operation status, hence people is continuing to develop and make electrical motor which is confirm requirement. Looking back to development of electric motor, people is striving and fighting for progress of electric motor from continuous current motor and A-C motor. People start to produce rare earth permanent magnet motor until NdFeB appeared and got support of advanced material, meanwhile, it moved improvement of relative industry products and make electromechanical integration reached update aspect,
Research institute of launch vehicle technology in China through research application to rare earth permanent magnet motor and control system, it has applied rare earth permanent magnet motor in rocket and missile successfully. It sticks to strategic orientation of “military quality decides institute and citizen quality makes institute emerging”, while Beijing Wanyuan Industrial Co., Ltd developing in entire stable development, it concerns more on embodying science and research, production merit, continuous discovery and develop new field, apply military mature hi-technology into citizen products industry field. The company will organize strong and powerful science and research team and invest massive labor and material, while developing rare earth permanent magnet wind power generator, rare earth permanent magnet traction motor for light rail and rare earth permanent magnet motor for petroleum exploitation to develop rare earth permanent magnet brushless DC speed regulating motor which produce large power.
Rare earth permanent magnet brushless DC speed regulating motor is outcome of combination of modern mater
