The four-shaded pole asynchronous motor stator of the invention can improve motor efficiency and motor torque.
本发明能够提高电机效率和电机扭矩。
The invention relates to a four-phase (8/6 pole) switch magnetic resistance motor control device of a single current sensor and a realized method thereof.
本发明涉及一种单电流传感器的四相（8/6极）开关磁阻电机控制装置及其实现 方法。
When the motor runs in four-pole mode, it is started at two-pole mode and taps A2 and A4 are then connected together. In the meantime secondary winding is open.
当电机作四极运转时，先按二极运转启动，然后切换开关使主绕组抽头A2与A4连接电机既作四极运转，此时副绕组开路。
