PROBLEM TO BE SOLVED: To provide a brushless motor achieved in size reduction and cost reduction by eliminating a bus bar. SOLUTION: A protrusion 54a and a connecting groove 54b are formed on an insulator 54 that covers a stator core 53, and an engagement hole 54c is formed at the protrusion 54a. A connecting fixture 57 having a terminal piece 57a is engaged with the engagement hole 54c, and the terminal piece 57a and a base 64a of an external draw-out pin 64 arranged at an connecting opening 65 of a bearing holder 60 are welded to each other. Since the external draw-out pin 64 is arranged at the bearing holder 60, a connecter can be eliminated, and furthermore, an axial height can be lowered by forming a welding space at the connecting opening 65. Furthermore, since welding can be performed after the assembling of a motor, work efficiency can largely be improved. COPYRIGHT: (C)2007,JPO&INPIT |
