将传感线圈功能集成到励磁绕组中用于非凸极直流游标磁阻电机的初始位置估计

This letter presents a novel mutual inductance detection method by integrating sensing coil function into field winding for the initial position estimation of nonsalient DC-excited vernier reluctance machines (DC-VRM). The key is to reutilize the field winding as a sensing coil by operating the power transistor states, and then the induced currents can be detected from the closed sensing coil when...
