Everyone should know the dc motor controller is a can realize dc motor controller can and mechanical energy conversion from each other. So it works, you know? Small make up to introduce below. Fixed inside a circular permanent magnet dc motor controller, when the current pass through on the rotor coil generates a ampere force, at the same time as the rotor coil and magnetic fields on the parallel, continue to turn, so by the magnetic field direction will change, at this point in the rotor at the end of the brush will follow transformation in contact, to change the direction of the electric current on the coil, lorentz force and direction, so that the motor controller to a direction of rotation. Through the introduction of the small make up, everybody to what did you learn about the working principle of the dc motor controller.
