【摘要】 无位置传感器无刷直流电机是无刷电机的发展方向。针对燃料电池汽车(FCV)空调系统运用反电动势法实现了对空调电机的无传感器控制,并提出了电机由外同步运行方式至自同步方式的最佳切换方法。更多还原

【Abstract】 Sensorless blushless direct current motor is the prospect of brushless direct current motor.Based on Back-EMF,the paper realized the sensorless control of BLDCM for AC in FCV.A new method is provided,which permits the sensorless BLDCM automatically search the best time to change its operation stage from separately-controlled synchronous mode to self-controlled brushless one.更多还原
