ABSTRACT:
Directional electromagnetic steel plates are laminated, and a plurality of stator and rotor core segments are produced by generating into an approximate U-shape so as to provide a U-shaped cross section of the lamination. The direction of high magnetic permeability of the directional electromagnetic steel plates is aligned during lamination with the direction along said U-shape. The side portions of the U-shape adjoin each other and are arranged along the circumference to produce the stator and rotor cores. As the electromagnetic steel plates are laminated, fluctuation in the components in the circumferential direction of the magnetic flux within the magnetic poles and salient poles can be reduced, and iron loss can thus be lowered. In addition, the direction of high magnetic permeability of the directional electromagnetic steel plates coincides with the direction of the magnetic flux creating a much stronger magnetic flux.
