一种新型混合转子结构无轴承电动机磁悬浮力的矢量控制
LEVITATION FORCE VECTOR CONTROL OF A NOVEL BEARINGLESS MOTOR WITH HYBRID ROTOR STRUCTURE
摘要
Abstract
Bearingless motors have the advantage of without mechanical wear and noise. The electromagnetic torque and levitation force for rotor rotation and suspension are generated by the motor itself. Based on the comparative study of toque and magnetic levitation force for a bearingless motor with different rotor structures by means of finite element analysis, this paper presents a new hybrid rotor structure, which has the advantages of both permanent magnet rotor and induction rotor. The proposed bearingless motor can not only produce larger electromagnetic torque and levitation force but also provide a way to realize decoupling control of levitation force through current vector orientation. A control system of the proposed bearingless motor with hybrid rotor structure based on DSP TMS320C32 and Xilinx CPLD has been set up. The vector control strategy of levitation force has been implemented.The tested results show that the proposed motor design and control strategy of the novel bearingless motor are feasible.关键词
