MAGNETIC ROTATING DEVICE, ELECTRIC MOTOR, AND ELECTRIC MOTOR GENERATOR

摘要

A high-efficient magnetic rotating apparatus and motor generator are provided which are capable of further reducing a detent torque. The magnetic rotating apparatus and the motor generator each includes a stator in which cores with a winding are disposed and a rotor in which permanent magnets are disposed. The permanent magnet has a magnetic pole of an N-pole or an S-pole and has a counter face, opposed to the core, with an inclination angle. In each set of magnet bodies, the two permanent magnets are so disposed that two counter faces have different magnetic poles and are inclined reversely. The two permanent magnets are magnetically connected through a joint member made of a magnetic material so that the two counter faces act as magnetic poles on both ends of the magnet body.
