Brushed Direct Current Motor

摘要

A brushed DC motor has a stator and a rotor. The stator has 2P magnetic poles, where P is an integer greater than 1. The rotor has a shaft, a rotor core, a commutator and a winding. The rotor core has m×P teeth, where m is an integer greater than 2. The winding includes several coil windings wound on the teeth and electrically connected to segments of the commutator. The commutator has 2m×P segments, where the 2m×P segments are divided into 2m groups, each group has P segments, the P segments are connected by an equalizer. The equalizer for at least one group of the 2m groups of segments and all the coil windings are formed by a single winding wire, wound continuously.
