Dc motor controller is introduced

For the composition of dc motor controller structure, do you understand? Below small make up to make a brief introduction. Dc motor controller is mainly composed of stator and rotor of two parts. The stator is refers to the dc motor controller runtime stationary part, main effect is to produce a magnetic field. Rotor is runtime rotating part, main effect is to produce electromagnetic torque and the induced electromotive force, which is to convert the energy of hub. The stator is composed of frame, main pole, commutating pole, end cover, bearing and brush device and so on. Rotor is by the rotating shaft, the armature iron core, the armature winding, commutator and fan, etc. Above all, for if you know something about the composition of dc motor controller.
