ことを特徴とする回転電機。[Claims for Utility Model Registration] A stator core formed in an annular shape, a spindle rotatably supported on the stator core side via at least an integral sliding bearing, and a rotor fixed to the spindle. Be prepared,
The stator core is provided with salient poles via a plurality of radially protruding arms for loading windings, and the rotor is provided with magnets so as to face each of the salient poles, In a rotating electric machine in which a predetermined rotating magnetism is formed between each of the salient poles and the magnet, each rotation in the left and right regions is determined by dividing the annular stator core into semicircles with the center line dividing the annular stator core into semicircles. A rotating electric machine characterized in that the number of salient poles is set asymmetrically in the left and right regions so that the magnetic balance is different.
