无轴承永磁同步电机转子初始定位策略
Initial rotor orientation strategy of bearingless permanent magnet synchronous motor
摘要
Abstract
To realize rapid steady starting of bearingless permanent magnet synchronous motor ( BPMSM) , a new initial rotor orientation method was proposed based on command current control. The suspension principle of BPMSM was given to analyze the necessary and sufficient conditions of achieving accurate position. The step angle and the positioning phase sequencer in initial orientation were optimized to identify 120° to 240° and to 0° initial orientation phase sequence. The experiments of three steps initial orientation without load were completed on BPMSM digital test rig to achieve the test wares. The results show that the orientation accuracy is controlled at the range of — 1 ° to 1 ° with minimum location resolution angle of 0.2° and with motor radial displacement under 200 pjn. The initial rotor orientation of BPMSM can be realized by the proposed strategy with rapid steady starting.关键词
