在SPM电机的每个磁极上缠绕一圈，可以在保持正交轴磁链动态的同时，修改直轴磁链动态。因此，产生了转子的动态各向异性。因此，该电机可用于通过高频注入信号利用各向异性转子特性的无位置传感器控制。文中描述了该电机的模型，并给出了描述电机动力学的主要方程。文中给出了仿真结果、设计提示和实验结果，以验证所提出的新型转子结构。
A turn wound around each pole of an SPM motor allows the direct axis flux linkage dynamics to be modified while preserving the quadrature axis one. Thus, a rotor dynamic anisotropy is created. Consequently, the motor can be used in a position sensorless control which exploits the anisotropic rotor features by high frequency injected signals. The model of the machine is described in the paper, and the main equations describing the motor dynamics are reported. Simulations, design hints and experimental results are reported so as to validate the proposed new rotor structure.
