Abstract

PURPOSE: To omit the fixing operation of a shaft and make manufacturing easy, and further, increase the strength of magnetic poles and improve rotor performance by forming a rotor body and a shaft of a permanent magnetic material in one piece.
CONSTITUTION: A magnet rotor 1 is made by forming a rotor body 1a and a shaft 1b of a permanent magnetic material in one piece. And it is used, for example, by magnetizing two poles N and S in the direction of a diameter. By so doing, the effective cross-sectional area of a magnet is increased by the shaft part and so the strength of magnetic poles is increased to improve performance, and at the same time, the fixing operation of the shaft is omitted and the manufacturing of the rotor is made easy.
