Kind Code:
A1
Abstract:
Provided by the present application is an end cover used for a brushed direct current motor, the end cover being provided thereon with a power supply, two carbon brushes, and two groups of a plurality of rod inductors connected in series; an end of a first group of a plurality of rod inductors connected in series is connected to a positive pole of the power supply, while the other end of the first group of a plurality of rod inductors connected in series is connected to a first carbon brush; an end of a second group of a plurality of rod inductors connected in series is connected to a second carbon brush, while the other end of the second group of a plurality of rod inductors connected in series is connected to a negative pole of the power supply. Further provided by the present application is a brushed direct current motor. In the present application, by means of disposing two groups of a plurality of rod inductors connected in series on an end cover of a brushed direct current motor, the inductance in a power supply circuit may be increased without increasing the axial length of a motor, thereby improving the EMC performance of the motor.
