Dc motor is dc motor to dc can be converted into mechanical energy or converting mechanical energy into direct current to the rotation of the motor. It is to be able to achieve direct current (dc) and mechanical energy transformation of the motor. When run it as a motor is a dc motor, converts electrical energy into mechanical energy. Make generator operation is a dc generator, the mechanical energy into electricity. There were many problems in the process of using the motor, what all have, in the form of problems arise when the problem of sound, this is our common one of the problems, it why there will be a different ring, when we how to repair? If the armature without axial channeling move caused knock against, should be a structure have loose phenomenon. 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 the ground up, try not yet words 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), see if there are in the process of slow down, if do not have that could determine the electromagnetic noise is, if no should be mechanical issues.
