: what is a brush motor has a motor, the coil and the commutator rotating, the magnetic steel and carbon brush don't turn, and by the direction of the coil current changes with the motor rotating commutator and brush. what is the brushless motor, brushless dc motor provided by different direction of current controller, to achieve the direction of the motor coil current alternates alternately, between rotor and stator of brushless motor without brush and commutator. brushless motor with electronic commutation replace the mechanical commutation, technically superior to brush motor. A brush motor carbon brush is easy to wear leads to reduced life spans. But the efficiency of the brushless motor within a certain range of current worse than a brush motor. But brushless motor driving up almost no noise, and life for more than 10 years. Based on the analysis of both pros and cons, brushless motor or superior to brush motor.
