PURPOSE:To obtain a simply constructed motor with a high performance by a method wherein a rotor consisted of a salientpoled permanent magnet with an N-pole and an S-pole on the axial direction, an armature to be axially excited to the N-pole and the S-pole and a prescribed auxiliary stator are provided. CONSTITUTION:On rotor 1 consisted of a salientpoled permanent magnet with an N-pole and an S-pole in the direction of an axis 2, an armature 3 with a U-shaped core to be excited by a wiring 5 are provided in such way that the S-pole and the N-pole are located in the axial direction facing reverse to the pole of the rotor 1. In addition, an auxiliary stator 4 consisted of a permanent magnet of narrow-strip type, for instance, is provided in order to have an S-pole and an N-pole in the same direction as the armature 2 and to have a gradually increasing magnetic force to the direction of rotation of a rotor 2. And in accordance with the pole location of the rotor 1, a current is applied to the winding of the armature 3, the rotor 1 is sucked and turning force is generated also by the auxiliary stator 4. |
