Title:
DC BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JP2007006603
Kind Code:
A
Abstract:
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.
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.
