PROBLEM TO BE SOLVED: To provide a DC brushless motor that has a simple structure, is low in price, improved in cooling performance, and achieved of high output, by installing a radiator plate composed of a nonferrous system material of high thermal conductivity to a bracket B on an anti-load side. SOLUTION: The DC brushless motor is constituted, such that the radiator plate 12 composed of the nonferrous system material of high thermal conductivity to the bracket B5 at the anti-load side, and the dimension of the radiator plate can be changed freely according to the output. By forming the radiator plate 12 into a regular or an irregular convex and concave shape, heat radiation efficiency is improved further. COPYRIGHT: (C)2007,JPO&INPIT |
