Brushed DC Motor Basics II

● Generates a stationary magnetic field that surrounds the rotor, this field is generated by either:

First let us look at the stator. As the name implies, the stator generates a stationary magnetic field that surrounds the rotor and this magnetic field is generated by either permanent magnets or electromagnetic windings.

2. Rotor

- Made up of one or more windings
- Commutation

Next is the rotor, also known as the armature. The rotor is made up of one or more windings.
When these windings are energized they produce a magnetic field. The magnetic poles of this rotor field will be attracted to the opposite poles generated by the stator, causing the rotor to turn. As the motor turns, the windings are constantly being energized in a different sequence so that the magnetic poles generated by the rotor do not overrun the poles generated in the stator. This switching of the field in the rotor windings is called Commutation.
