摘要： On an AC permanent magnet switched reluctance motor stator seat, “C-shaped” or “U-shaped” excitation salient pole pairs or compound excitation salient pole pairs are set up in a balanced way. Excited by excitation current, the permanent magnet flux of compound excitation salient pole pair is imported into the main loop of excitation flux to form compound excitation magnetic potential. On the rotor support, permanent magnets are fixed at the same interval, and the magnetic polarity of neighboring permanent magnets on a same rotating surface is different. When the rotating shaft rotates, two magnet pole faces of each permanent magnet on rotor support will be dead against the two ports of each excitation salient pole pair on the stator, forming a closed magnetic loop with air gap.
