The rotor speed of an asynchronous motor is always slightly lower than that of the rotating magnetic field. The rotor speed of the synchronous motor is independent of the load size and is always kept at synchronous speed. DC Generator Working principle is to the armature coil induction alternating electromotive force, rely on the commutator with the electric brush reversing effect, make it from the brush end to become a DC EMF principle. The direction of the induction electromotive force is determined by the right hand rule (the magnetic line points to the palm, the thumb points to the direction of the conductor, and the other four points are the direction of the inductive electromotive force in the conductor).
