Abstract

PURPOSE: To compact a yoke and form the outer peripheral surface in a circular shape, by making the yoke at the sections fitted with magnets, thicker by the reduced thickness of the magnet, gradually as the thickness of the yoke is directed closer to the magnetizing side from the demagnetizing side.
CONSTITUTION: A stationary field device 1 is provided with a cylindric magnetic yoke 2, and on the inner peripheral surface of the yoke 2, the ferritc permanent magnets 3 of four magnetic poles 4 are directly fitted. The yoke 2 is provided with a revolving armature 4. The permanent magnets 3 get thinner as the thickness is directed closer to the magnetizing side from the demagnetizing side of the rotor flux of the revolving armature 4, and the yoke 2 at the sections with the fitted permanent magnets 3 is made thicker by the reduced thickness of the permanent magnets 3, gradually as the thickness of the yoke 2 is directed closer to the magnetizing side from the demanetizing side.
