Abstract

PURPOSE:To improve the efficiency of an apparatus at a high-speed rotation and prevent the heat generation of a motor driver by arranging a coreless type stator coil within the space of a rotor permanent magnet fastened to a shaft and an outer yoke. CONSTITUTION:An inner yoke 2 and a permanent magnet 4 reinforced in its outer peripheral face via a cylindrical reinforcing cup 3 are fastened to a shaft 1, and a cylindrical outer yoke 5 is fastened to the outer periphery side of said reinforcing cup 3 with provision of a cylindrical space 6 between said parts, to form a rotor 7. Then, a coreless type stator coil 9 fixed to an outermost housing 8 is arranged within a space 6 to form a stator 10. Thus, because the inner yoke 2, permanent magnet 4 and outer yoke 5 of said rotor 7 turn on the same shaft 1, no excess current flows even if a motor revolves at high speed, the efficiency if said motor is improved, and a motor driver can be prevented from generation of heat.
