Abstract:
An electromagnetic steel plate forming member provides the two magnet holes for inserting therein the two permanent magnets per pole along the V-shape, which are provided in the region of the radial pole pitch lines OP provided in the rotor core at the predetermined pole pitch angle θ, one magnet hole is displaced in a direction apart from the center line OC of the pole pitch lines OP, and the other magnet hole is displaced in a direction approaching to the center line OC of the pole pitch lines OP.
