Unlike other categories of electric motors, only DC motors do not need a controller so that you can alternate current in the motor bearings. Thus, the winding of a DC motor winding is effected mechanically. There is a switch on the shaft of this motor, so as the motor rotates, the carbon brushes act on the switch, coming in contact with different segments of the device. As the motor rotates, its bearings are intermittently energized in a sequence, so that the magnetic poles generated by the rotor can not overcome the poles caused by the stator.
This field change in rotor bearings is called commutation. The stator is responsible for forming a stationary magnetic field that surrounds the rotor 1125-4-100-SP. This field arises due to the operation of permanent magnets and electromagnetic coils. The different types of DC motors are differentiated by the stator construction or even by the way the magnetic bearings were connected to the power supply. These segments are connected to separate rotor bearings, so a dynamic magnetic field is produced inside the motor at the instant which voltage is applied between the motor brushes.
