PURPOSE:To rigidly and accurately mount a permanent magnet on a yoke ring by forming notches to be engaged with permanent magnets at the yoke ring side and forming a groove matched at the notch at the permanent magnet side. CONSTITUTION:Permanent magnets 20 are arranged circumferentially of a yoke ring 15 to form a rotor. Notch 16 to be engaged with permanent magnets are formed at the ring 15 side, and grooves 19 are formed to be matched to the notches 16 at the permanent magnet 20 side. The permanent magnets 20 are formed as flexible rubber magnets. The ring 15 is coupled to the magnets 20 by engaging the magnets 20 with the notches 16 of the ring 15. |
