Abstract

The invention provides a motor comprising a metal shell, an electric brush and a capacitor. The capacitor comprises a first metal sheet and a second metal sheet which are not packaged, and an insulating sheet which is clamped between the two metal sheets. The first metal sheet is electrically connected with the electric brush. The second metal sheet is electrically connected with the metal shell. The unpackaged capacitor is adopted in the motor so that space occupied by the capacitor is effectively reduced. Besides, the sheet-shaped capacitor can be flexibly fixed inside the narrow space of the motor or an end cover, and the accommodating space almost does not need to be specially reserved for the capacitor so that miniaturization of the motor and the end cover is facilitated. The invention also provides an end cover component of the motor.

Description

technical field [0001] The invention relates to a motor and an end cover assembly thereof. Background technique [0002] During the working process of a motor with brushes and commutators, there will be electric sparks and radio frequency interference signals when the commutator rotates relative to the carbon brushes. RFI signals can propagate out of the motor and interfere with the power supply, which in turn can interfere with circuits connected to that power supply or other unshielded circuits near the motor. Usually, a choke coil is connected in series on the motor or a capacitor is connected in parallel on the motor to filter out the radio frequency interference signal. However, the choke coils or capacitors connected to the motor are usually packaged products on the market, which are usually large in size and occupy a part of the valuable space inside the motor, which is not conducive to the miniaturization of the motor. Contents of the invention [0003] In view o...
