Title:
How to manufacture the brush motor commutator and this which controlled the spark
Document Type and Number:
Japanese Patent JP6262476
Kind Code:
B2
Abstract:
A commutator (10, 40, 54, 60, 64, 70, 76, 78) for a brush motor includes a cylindrical insulating base (12), a plurality of segments (14) disposed on an outer surface (68) of the insulating base (12), circumferentially spaced from each other, and defining a plurality slots (42) between adjacent segments (14), and a plurality of insulating outgas elements (24) capable of releasing a gas having a lower conductivity than air and disposed on the outer surface (68) of the cylindrical insulating base (12). Each outgas element (24) is located between a corresponding pair of the plurality of segments (14), having a gas releasing surface (26) between the corresponding pair of segments (14) and lower than outer surfaces (28) of the corresponding pair of segments (14). A method for making a commutator is also provided.
