摘要
针对横向磁场直线开关磁阻电机(TFLSRM)的结构,利用各相绕组磁链在磁极中随位置不同而产生的差异,提出了一种TFLSRM换相位置间接检测方法。该方法只需在初级边附加一套具有独立磁路的三相检测绕组,即可获得各相换相位置参考点,并能克服电机启动前各检测绕组磁链恒定不变而无法确定上升区与下降区的不足。结果表明,所提方法可方便地实现对TFLSRM换相位置的检测。
In the light of the structure of TFLSRM, an indirect detecting method of commutation position is given by use of the flux differences of different phase of windings as the position changes. By adding of a 3-phase detecting winding with independent magnetic circuit in primary side, the reference point for commutation of each phase could be achieved. And the defects could be removed that raising or dropping zone could not be determinod due to the constant flux of each detecting winding before the motor start-up. The results show that with the proposed method the commutation position could be easily detected.
