Brush direct-current motor

Abstract

The invention relates to a brush direct-current motor. The brush direct-current motor comprises a base, a stator core and a rotor, the stator core is shaped in a circular column, and the rotor is embedded into the stator core. The brush direct-current motor is characterized in that the base is shaped in a circular column and arranged on an outer surface of the stator core in a sleeving manner, support legs are fixedly at the lower end of the base, a snakelike water flow channel is circumferentially formed in a wall of the base, a water inlet tube and a water outlet tube which are respectivelycommunicated with a head end and a tail end of the snakelike water flow channel are arranged at the bottom end of the base, a water storage tank is fixed on the support legs, and a miniature water pump connected with the water inlet tube is arranged in the water storage tank. Through combination of the snakelike water flow channel in the wall of the base and the miniature water pump in the water storage tank at the bottom of the base, water in the water storage tank can be pumped into the snakelike water flow channel and then is enabled to circulate between the water flow channel and the waterstorage tank, so that high temperature generated during working of the motor can be reduced, and on the other hand, weight of the motor can be increased by adding water into the water storage tank fixed at the bottom of the base, and vibration generated during working of the motor can be alleviated.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a brushed DC motor. Background technique [0002] The basic components of a brushed DC motor include the frame, stator, rotor, brushes and commutator. The stator includes a shell and an iron body for generating the main magnetic field. The rotor includes a rotating shaft, steel sheets and windings wound on the steel sheets. The commutator is sleeved at the input end of the rotating shaft. The electric energy of the DC power supply passes through the brushes and the commutator in turn. The commutator enters the winding in the rotor to generate armature current, and the magnetic field generated by the armature current interacts with the main magnetic field to generate electromagnetic torque, which makes the motor rotate and then drive the load.

AI Technical Summary

Problems solved by technology

[0003] When the existing brushed DC motor is in use, the body heats up seriously, and it is easy to burn out the motor after long-term uninterrupted use. In addition, during the working process of the motor, the vibration of the motor is relatively serious, and other heavy objects are often required to be pressed on it, which is troublesome and the motor is easily damaged. Separated from heavy objects; in addition, the structure of the brushed DC motor is complicated, and it is troublesome to assemble and disassemble, especially the disassembly and assembly between the base and the stator.
