AXIAL GAP TYPE BRUSHLESS VIBRATING MOTOR HAVING DRIVING CIRCUIT UNIT, CONCERNED WITH IMPROVING INNER STRUCTURE OF BRUSHLESS VIBRATING MOTOR

摘要

PURPOSE: An axial gap type brushless vibrating motor having a driving circuit unit is provided to install easily the driving circuit unit therein and reduce the size by improving an inner structure of the brushless vibrating motor. CONSTITUTION: An axial air gap type magnet includes a plurality of magnetic poles are installed at a rotor yoke. An eccentric rotor is installed at the rotor yoke. A shaft(2) is used for supporting the eccentric rotor. A shaft support part for supporting the shaft is installed in a center of a yoke bracket(1). A stator base as an additional element is installed at the yoke bracket. Two air-core armature coils(5A,5B) are installed in the stator base. A hall sensor is installed at the stator base. A stator includes a driving circuit member in order to receive an output the hall sensor. A cover member is used for covering each component. A magnetic part and a non-magnetic part are formed at a part of the stator. An opening of the cover member is formed at an outer circumference of the cover member.
