You will come across many types of motors. People have been trying different ways to make a motor nearly as long as they have been messing with electricity. Here is a brief overview on some types of DC motors.
Brushless DC Motors
The brushless DC motors are cousins to the DC PM motor but instead of using brushes for commutation, they usually use some type of electronic control. To accomplish this, usually the inner side of the motor contains permanent magnets (where the armature is in the DC PM motor). This is known as rotor. The windings are on the outside and are referred to as the stator, or field windings.
