Abstract
The utility model provides a dc motor with a brush which is equipped with a temperature measuring device, relating to the technical field of dc motors. The dc motor comprises a casing, a stator and a rotor, wherein the stator is fixed in the casing and connected with the casing, the rotor is arranged in the stator, a brush box is arranged over a commutator of the rotor, the brush is arranged in the brush box and connected with a temperature measuring component, and a signal output end of the temperature measuring component is connected with a motor control system. According to the utility model, the temperature measuring component is fixed with the upper portion of the brush, and then led into a conjunction box of the motor to measure the temperature of the brush of the motor; the temperature is back fed to the motor control system, and alarming is carried out when the temperature exceeds a temperature limit value (commonly 80 DEGC); thus, the frequency of faults caused by too high temperature of the surface of the motor commutator is reduced, the service life of the motor is improved, operational reliability of the motor is enhanced, and working efficiency is improved.
Description
Technical field
The utility model relates to the technical field of direct current machine.
Background technology
Existing direct current machine mainly comprises casing, stator and rotor, and stator is fixedly connected in casing, and rotor is arranged in stator, and the commutator of rotor top arranges brush box, and brush is set in brush box, due on brush without temperature element, can't feed back the temperature of brush.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of direct current machine of brush band temperature measuring equipment is provided, and can feed back the temperature of brush, thereby improves the useful life of motor.
The purpose of this utility model is achieved in that the direct current machine of brush band temperature measuring equipment, comprise casing, stator and rotor, stator is fixedly connected in casing, rotor is arranged in stator, the commutator top of rotor arranges brush box, brush is set in brush box, on described brush, connects temperature element, the signal output part of temperature element is connected with electric machine control system.
The utility model is fixed on brush top by temperature element, then temperature element is drawn and receives in connection box for motor, and the temperature of the brush of motor is measured, and feeds back in electric machine control system, surpasses temperature limit (being traditionally arranged to be 80 ℃), can be reported to the police.This device has reduced the engine commutator surface and has damaged the number of stoppages because of excess Temperature, has improved the useful life of motor, increases the motor reliability of operation, has improved operating efficiency.
For convenient fixing, temperature element is fixed on brush by glue.
