在没有位置传感器的情况下操作永磁同步电机（PMSM）的优点很多并且是众所周知的。本文研究了增量电感中的空间谐波的影响及其对电机凸极的影响。空间谐波的影响完全是由于机器（即，饱和显著性分布）。通过电感分析和两个类似的永磁同步电机的电感轮廓的测量结果说明。通过Matlab/Simulink嵌入式有限元（FE）机器仿真，电感分布中的空间谐波与位置估计失真相关。两台机器的无传感器操作的显着差异被发现与电感配置文件。这说明电感分布可以为机器设计提供信息，以提高无传感器能力。
Advantages of operating a Permanent Magnet Synchronous Machine (PMSM) without a position sensor are many and are well known. This paper presents a study of the effects of space harmonics in the incremental inductances and their impact on the machine saliency. The effects of space harmonics exclusively due to the machine (i.e., the saturation saliency distribution) are given particular consideration. The results are illustrated through inductance analysis and measurement of inductance profiles of two similar PMSM machines. The space harmonics in the inductance profiles are correlated with the position estimate distortions through a Matlab/Simulink embedding finite element (FE) machine simulation. Significant differences in sensorless operation of the two machines are found which correlate to the inductance profiles. This illustrates that inductance profiling can inform upon machine design in order to improve sensorless capabilities.
