ONE DIRECTIONAL ELECTRIFICATION-TYPE BRUSHLESS DC MOTOR PROVIDED WITH AC VOLTAGE OUTPUT WINDING AND MOTOR SYSTEM

摘要

[PROBLEMS] To provide a one directional electrification-type brushless DC motor having AC voltage output winding that can simultaneously show a function of a motor, which can continuously obtain constant torque, and a power generation function which can obtain continuous electromotive force. [MEANS FOR SOLVING PROBLEMS] The DC motor is provided with a disk (5) fitted to a frame (3), a plurality of plate-like permanent magnets (6) arranged on the disk (5) at equal intervals at a periphery of the disk (5), magnetic body cores (70(A)) fixed to the frame (3) in accordance with a plurality of the permanent magnets (6), windings (71(A)) which are wound to the magnetic body cores (70(A)) and to which DC power is supplied, a prescribed number of magnetic body cores (70(B)) fixed to the frame (3) and windings (71(B)) wound to the magnetic body cores (70(B)) and connected to a power consumption device. The permanent magnets (6) are positioned in such a way that an angle that a straight line passing a center of the disk (5) and centers of the permanent magnets (6) and a normal line in a center of a magnetic pole face of the permanent magnet (6) make is set to be 0° to 60°.
