Title:
CARBON BRUSH DEVICE AND MOTOR
Document Type and Number:
Japanese Patent JP2011055677
Kind Code:
A
Abstract:

To provide a carbon brush device with improved efficiency.

One end of a main pigtail 66 is connected electrically at the base end of a carbon brush 65. One end of a bypass pigtail 67 is connected electrically at a position on the side closer to the tip than the base end of the carbon brush 65. Since the resistance values of the carbon brush 65 between a commutator 37 for a motor and a cap 68 and each pigtail 66 and 67 can be reduced, losses in the carbon brush 65 and each pigtail 66 and 67 can be suppressed, thus improving efficiency.
