Abstract:
To manufacture a permanent magnetic motor having saliency at a low cost, a permanent magnet motor includes a stator provided with an armature winding configured to form a plurality of phases, a rotor having a surface facing the stator, the rotor including a permanent magnet disposed to face the stator, the permanent magnet having a plurality of magnetic poles arranged in a circumferential direction of the rotor, and a conductive member made of a conductive material and disposed on the surface of the rotor facing the stator.
