Motor with reduced clogging torque incorporating stator salient poles and rotor magnetic poles

摘要: In the permanent magnet motor of present invention, where P is an integer not smaller than one, number magnetic poles a rotor (22) set to 2P, and salient stator field core (21) 3P. The pole section (21a) each provided with two supplemental grooves (24). A interpolar angle 4θ, such that (24) are arranged in positions at angles θ 3θ respect center winding slot (27) circumferential direction rotor. With this structure, fundamental wave component clogging torque removed having low provided.
