How to solve the abnormal sound generated in the operation of dc motor

Issuing time:2019-03-12 15:28

Dc motor refers to the rotating motor that can convert dc electrical energy into mechanical energy or mechanical energy into dc electrical energy.It is a motor that can realize the conversion of direct current electrical energy and mechanical energy.When it operates as a motor, it is a dc motor, which converts electrical energy into mechanical energy.When operating as a generator, it is a dc generator, which converts mechanical energy into electrical energy.


There are many problems in the process of using the motor, what kind of form are there, when the problem of abnormal sound, this is one of our common problems, why it will appear abnormal sound, how do we repair it?


If the armature is not axial movement caused by knock, it should be loose structural parts.We please remember a rule: is the pole on the gasket don't easy to get rid of, will affect the motor function and running conditions, problems about noise has the following methods: driving motor of electric control system of power supply access oscilloscope waveform have short wave head, lacks can produce vibration and noise, when the second compensation coil and armature connection ever pick up against.


Check from scratch, try not yet again should be magnetic circuit is too strong, electromagnetic noise, to drive the motor to the rated speed, a certain range to see if there is, then cut off power supply), whether in the process of slow down and, if do not have that could determine the electromagnetic noise is, if no should be mechanical issues.
