PROBLEM TO BE SOLVED: To provide a motor having a structure capable of down-sizing, while suppressing electromagnetic noise.SOLUTION: In a motor, a coil is wound around a core by concentrated winding. A brush card assembly has at least one pair of brushes of different polarity from each other, arrange in the circumferential direction and connected electrically via commutators and coils, at least one X capacitor for connection in parallel with the brush, at least two Y capacitors for connection in parallel with the brush, and a brush card for holding the brushes and X capacitor and Y capacitors. The brush card has a ground part of reference potential. The X capacitor is located between the brushes in the circumferential direction. The Y capacitors are connected electrically with the ground part.SELECTED DRAWING: Figure 3 |
