ブラシ付きモーター
Document Type and Number:
Japanese Patent JP4882189
Kind Code:
B2
Abstract:
It is to provide a brush-equipped motor enabled to be used for a long time without performing operations and without interruption even when the brush wears out. When a rotor is caused to perform a turning operation, cam projections similarly start to perform a turning operation. Then, an abutting part, at which each of the cam projections contacts with a spring piece part of a corresponding one of the first brushes, gradually moves to an end of the first brush. Thus, the spring piece part of each of the first brushes is gradually and elastically deformed in a direction in which brush bodies come away from a commutator. When the turning operation continues still more, an end of each of the second brushes comes off a corresponding one of the cam projections, so that the brush bodies thereof contact with the surface of the commutator.
