<p><P>PROBLEM TO BE SOLVED: To reduce, more than in the prior art, a rotating magnetic field which arises in an iron core composed of a combination of a longitudinal component and a lateral component. <P>SOLUTION: A lamination direction of a directional electromagnetic steel plate in longitudinal components 11a-11c is set to be a depth direction of an iron core for an electric power apparatus 10, and a lamination direction of a directional electromagnetic steel plate in lateral components 12a-12d is set to be a height direction of the iron core for the electric power apparatus 10. Then, an interface 13 in the depth direction of the center longitudinal component 11a and lateral components 12a-12d is composed of three planes. The generation of rotating magnetic field in the interface 13 is further controlled than in the prior art. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
