ABSTRACT:
A method of manufacturing a permanent magnet rotor comprising a rotor yoke (2) of a rotor (1) which is formed by laminating a large number of steel sheets (4), (14), (24), (34) and (44), has 2n times (n is a positive integer) of magnetic poles (5) on the outer periphery, has slots (6) at the bases of all or every other magnetic poles at a substantially equal distance from a rotatable shaft hole (7), and has permanent magnets (3) for a field inserted into the slots, and a method for producing it. It has a structure that the permanent magnets for the field are prevented from coming out, or the permanent magnets for the field have their faces treated in order to improve the safety and reliability of the permanent magnet rotor.
