PROBLEM TO BE SOLVED: To obtain a permanent magnet rotor wherein a plated layer is almost uniform in the central part and the end portion of the permanent magnet for a field system and has no trace of electrode, when an electroplated permanent magnet for a field system is used, and moreover can simplify processes and shorten the manufacturing time. SOLUTION: In this permanent magnet rotor 1, a yoke 2 is formed by laminating many steel sheets 4, having 2n times (n is positive integer) the number of magnetic poles 5 are formed on the outer periphery, slots 6 are formed for all the magnetic poles at equal distances from a rotating shaft hole, or are formed at alternate base parts, and permanent magnets 3 previously electroplated for a field system are inserted in the slots. For the permanent subjected to electroplating, an electrode which is electrically continuous to the permanent magnet is moved relatively to the permanent magnet. |
