Design of Bearingless Motor Aerosol Control System

DUAN Chun-xia,GE Yun-wang,JIANG Jian-hu(Luoyang Institute of Science and Technology,Luoyang 471003,China)  
Bearingless motor combines characteristics of alternating current motor and magnetic bearing.It will make magnetism aerosol bearing winding of producing magnetism suspending power set in the electrical machinery stator.It omit the special magnetism aerosol bearing.Through torque winding and suspending power winding decoupling control,the electrical machinery rotor simultaneously has the function of producing torque and aerosol.The bearingless electrical machinery can realize high speed,does not have the friction and has ather aspects of fine performance.It is one of current research hot spots.The design of bearingless electrical machinery aerosol control system is the key to this research.The paper introduced the basic principle of the bearingless motor aerosol control,Designed based on the torque winding rotor magnetic field direction detection aerosol control system.
