发明名称 Face opposing type motor
摘要 A face opposing type motor has a rotor yoke fixed to a hollow rotating shaft disposed in a non-contact bearing device; the non-contact bearing device having a fixed shaft inserted into the hollow rotating shaft; a rotor magnet held by the rotor yoke; and a driving coil substrate having a face opposed to the rotor magnet. The rotor yoke has a rotor magnet fitting portion fitted to an outer circumferential face of the rotor magnet so as to hold the rotor magnet by this rotor magnet fitting portion. In accordance with such a structure, it is possible to provide a reliable face opposing type motor having an excellent quality and cheaply manufactured by improving a system for holding a rotor magnet.
