PROBLEM TO BE SOLVED: To solve the problem that an adhesion process becomes necessary for manufacturing a rotator and productivity is deteriorated since adhesives for fixing a permanent magnet to a slit hole are conventionally used.;SOLUTION: The rotator for a permanent magnet type synchronous motor includes: a rotator core which has a shaft insertion hole, and a magnet insertion hole approximately in the radial direction of which a sagged recess is formed and extends in the axial direction; and a permanent magnet which is buried in the magnet insertion hole, and in which a projection which projects toward the recess is formed, and which extends in the axial direction. According to this invention, it is prevented that the permanent magnet comes out from the rotator core without using a special fastener fixture.;COPYRIGHT: (C)2012,JPO&INPIT
