  The inductance space distribution curve of brushless DC motor is non-sine waveform because of its centralized stator windings and 120 degree-wide permanent magnet. These factors make brushless DC motor in multiple saliencies and make the position estimation more difficult.

  永磁无刷直流电动机的集中绕组及120°的永磁体宽度使其电感系数在空间呈非正弦分布,其高次谐波尤其是二次谐波不可忽略,这一特点使得永磁无刷直流电动机表现出多重凸极现象,给位置估计带来困难。
