<P>PROBLEM TO BE SOLVED: To provide a brushless motor capable of improving the yield of manufacturing a bus bar and reducing the manufacturing cost in manufacturing a bus bar unit. <P>SOLUTION: The brushless motor includes a stator having coils of a plurality of phases wound therearound a rotor rotatably provided on the stator, and a bus bar unit 17 for supplying power to the coils. In the motor, the bus bar unit 17 is formed in such a way that phase bus bars 47U-47W provided for each phase and supplying power to the coil of each phase and a circular neutral point bus bar 48 forming a neutral point are each stacked on a resin mold 46, and the phase bus bars 47U-47W and the neutral point bus bar 48 are embedded in a state of being insulated from each other. The neutral point bus bar 48 is made of a plurality of bus bar pieces split in a circumferential direction, and each bus bar pieces is provided with a connection 82 for connecting adjacent bus bar pieces 81. <P>COPYRIGHT: (C)2011,JPO&INPIT |
