Title:
回転電機およびそのブラシの製造方法
Document Type and Number:
Japanese Patent JP4496415
Kind Code:
B2
Abstract:
The present invention discloses a rotating electric machine and manufacturing method of the electrical brush of the rotating electric machine, which provides a low-cost electrical brush capable of compromising the long life of the electrical brush and shorting the running handling time or having no need of running and processing the two aspects. The rotating electric machine has a glide plane (14) formed on one end of the brush (4) along the concave curved face of the external circumstance surface of a commutator (11); and a removing section(15), formed in a concave curved face in the axial direction, gradually left from the external circumstance surface of the commutator (11) to the other axial direction end of the brush (4) from the glide plane (14), and simultaneously formed a smooth surface without concave-convex in then radial direction at the rotation direction side of the commutator (11). In addition, the method includes a process of continuously performing cutting process to the rotation direction side of the commutator (11) to form a removing section(15).
