The present invention provides a permanent
magnet rotating electrical
machine capable of achieving high output. In order to solve this problem, a non-magnetic part is provided at both ends of a pole, and the angle of the minimum
magnetic circuit part and the angle of the
magnet generated by the non-magnetic part are utilized. The width of these two parameters adjusts the waveform of the
induced voltage and the
voltage of the motor. Assuming that the
pitch in the circumferential direction of the tooth core with respect to the central axis of the rotor is τs (degrees), the circumferential width between the minimum radial width portions of the pair of
magnetic circuit parts with respect to the central axis of the rotor is When the opening angle is set to θ (degree), θ(n+Y)×τs (n is an integer above 0), the winding method of the
stator winding is distributed winding, let Y=0.5, the winding method of the above
stator winding is When concentrated winding, let Y=0.9~1.2. In addition, by dividing the
magnet forming one pole into two parts and providing a bridge part therebetween, it is possible to provide a permanent magnet type rotating electrical
machine suitable for high-speed rotation.
