Dc motor controller is composed of stator and rotor of two parts.
Small make up take you look at today.
Stator dc motor controller refers to the runtime stationary part, composed of frame, main pole, commutating pole, end cover, bearing and brush device and other parts, the effect is to produce a magnetic field.
Dc motor controller of rotor and stator, on the other hand, is to run when the rotating part, by a rotating shaft, the armature iron core, the armature winding, commutator and fan and other parts, the effect is the electromagnetic torque and inductive electromotive force.
Above is introduced for stator and rotor dc motor controller in general, if you want to know more detailed, consult us.
