摘要 |
Powder produced by abrasion due to sliding between a brush and a commutator is prevented from moving toward a rotor. A recess is provided between the rotor and a slide face of the brush and the commutator, where powder produced by abrasion at the brush may enter into a motor and increase sliding resistance of the rotor. Thus, there is no such powder produced by abrasion entering into the motor as increasing sliding resistance of the rotor.
