Abstract

PURPOSE:To obtain a motor capable of passing a light or the like through the center by mouting a stator and a magnet rotor respectively formed in hollow ring shape at a ring-shaped bearing unit made of inner and outer wheels in a faced manner. CONSTITUTION:A ring-shaped bering unit 6 made of inner and outer wheels 9, 8 is formed. Guide grooves are formed on the facing surfaces of the wheels 9, 8, are rotatably formed with balls 7 disposed therebetween, a stepped part for installing the rotor is formed at the wheel 9, and a stepped part for installing the stator is formed at the wheel 8. A magnet rotor 5 formed in a hollow ring shape is secured directly to the rotor installing unit of the wheel 9, the stator 1 formed coaxially in a ring shape is fixedly faced to the stator installing unit of the wheel 8, thereby obtaining a motor having a cavity at the center.
