Japanese Patent JP6682919
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor that can suppress occurrence of spark in a power feeding brush with a low electric resistance value out of a plurality of power feeding brushes.SOLUTION: Two power feeding brushes 64 of an anode and two power feeding brushes 64 of a cathode sequentially contact a plurality of segments 48 of a commutator 45 in a sliding manner. Each power feeding brush 64 is held inside a brush holding part 63 provided for a brush holder, and a rear end face of the brush is energized toward the commutator 45 by an energizing member 65. One first power feeding brush of the anode has a lower electric resistance value than the other second power feeding brush of the anode. Further, in the first power feeding brush and the second power feeding brush 82 of the anode, the second power feeding brush 82 has slower time of separating from the segments 48. Furthermore, a rear end face 82b of the second power feeding brush 82 is inclined such that a vector of energizing force F by the energizing member 65 is directed to a front side in a rotation direction R of the commutator.SELECTED DRAWING: Figure 7
