Motor provided with electric brushes

Abstract

The present invention puts forward a motor provided with electric brushes, and solves the problem that an electric brush box in the prior art is not easy to replace, so that a motor is complicated in installation and troublesome in maintenance. The motor comprises a casing, a stator, a rotor and a commutator, wherein the casing consists of a shell, a front end cover and a rear end cover, each electric brush box is horizontally provided with a containing cavity therein, an electric brush assembly is detachably arranged in each containing cavity, each electric brush assembly comprises a brush carrier provided with a through hole and an electric brush arranged in the through hole, a plurality of conducting rings are uniformly distributed on the sidewall of the electric brush, a brush bristle hole is arranged between every two adjacent conducting rings, brush bristles are welded in the brush bristle hole, the brush bristles are formed by combination of a plurality of metal wires, one end of the brush bristle is contacted with the brush carrier, the other end of the brush bristle is fixedly connected with a wire, a tail end of the wire is connected with a limiting piece, the electric brush box penetrates the rear end cover of the motor, and a brush cover is rotatably fastened to the external part of the electric brush box. Through adoption of the motor of the present invention, the electric brush assembly can be conveniently disassembled at any time, thereby greatly simplifying maintenance work.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor provided with electric brushes. Background technique [0002] The existing motor with brush assembly mainly includes a casing, a stator located in the casing, a rotor and a commutator. The brush box is installed inside the motor, and the brush box and the rear end cover are generally connected by screws, and then the rear end cover is fixed with the casing. Due to the inevitable wear and ablation of the internal components of the brush box during work, the replacement cycle of the maintenance box of the brush box is relatively short, and because the components in the brush box are installed inside the motor, each time the maintenance box replaces the motor Brushes all need to disassemble the motor, which not only wastes time, reduces the utilization rate of the equipment, but also shortens the service life of the motor due to the increased number of disassembly and assemb...
