Electromagnetic DC motor The electromagnetic DC motor is composed of stator poles, rotor (armature), commutator (commonly known as commutator), brushes, housing, bearings, etc. The stator poles (main poles) of electromagnetic DC
Utilizing the characteristics of electromagnetic noise that varies with the strength of the magnetic field, the size of the load current, and the level of conversion, the power supply is suddenly cut off after a period of quiet listening to the motor running at no load
