Abstract
A brush direct current motor has a stator with a plurality of coils that correspond to a number of stator windings, a rotor with a number of poles, and a commutator. The commutator is connected to a first terminal of a direct current power source to convert the power into N phase alternating current. One end of each stator winding is connected to a respective phase of the alternating current via a brush and the other ends of the stator windings are connected to the second terminal of the direct current power source.
