PURPOSE:To provide a reliable brushless motor incorporating a power circuit for control circuit and a regulator. CONSTITUTION:The brushless motor consists of a stator core having stator windings of a plurality of phases wound around them with an insulating layer in-between; a permanent magnet rotor held by a bearing so that it can freely rotate; and a printed wiring board mounted with a group 2 of switching power elements, a control circuit 3, a power circuit D for the control circuit 3, and a regulator 9. The motor is fed only with power for motor drive, and power for the control circuit is generated and supplied from the motor driving power using the power circuit D for the control circuit the regulator 9 built in the motor. |
