本文提出了基于注入式自检测（无位置传感器）控制方法的表面永磁（SPM）电机具有高度对称的转子。两个合适的位置相关的空间显着性信号进行比较。这两个信号涉及由于定子齿饱和引起的电感变化和由于高频（HF）涡电流损耗引起的电阻变化。有限元分析（FEA）进行调查的性质，两个显着性信号在不同的SPM机。讨论了闭环自感知控制的实现方法和优点。本文包括实验比较评估电阻为基础的与电感为基础的闭环自感知控制性能的SPM机使用集中绕组。
This paper presents injection-based self-sensing (position sensorless) control methods for surface permanent magnet (SPM) machines with highly symmetric rotors. Two suitable position-dependent spatial saliency signals are compared. The two signals relate to inductance variation due to stator tooth saturation and resistance variation due to high frequency (HF) eddy current losses. Finite element analysis (FEA) is performed to investigate the properties of two saliency signals in different SPM machines. Implementation methods as well as advantages for closed-loop self-sensing control are discussed. This paper includes experimental comparative evaluation of resistance-based versus inductance-based closed-loop self-sensing control performance in a SPM machine using concentrated windings.
