<P>PROBLEM TO BE SOLVED: To provide a brushless motor with improved reliability in the brushless motor having a built-in power source circuit for a control circuit and a regulator. <P>SOLUTION: The brushless motor includes a stator core in which a plurality of stator windings are wound through an insulating layer, a permanent magnet rotor held rotatably at a bearing, and a printed circuit board which mounts a switching power element group 2, the control circuit 3, the power source circuit D for the control circuit, and the regulator 9. Only power for driving the motor is supplied to the motor. Power for the control circuit is generated from the power for driving the motor by using the power source circuit D for the control circuit contained in the motor and the regulator 9, and supplied. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
