The working principle of DC generator: the principle that the alternating electromotive force is induced in the armature coil, and the commutator cooperates with the brush to change the direction, so that it becomes a direct current electromotive force when it is drawn from the end of the brush. The direction of the induced electromotive force is determined according to the right-hand rule (the magnetic induction line points to the palm of the hand, the thumb points to the direction of movement of the conductor, and the other four fingers point to the direction of the induced electromotive force in the conductor). The direction of force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces form a torque acting on the armature, which is called electromagnetic torque in a rotating motor, and the direction of the torque is counterclockwise in an attempt to make the armature rotate counterclockwise. If this electromagnetic torque can overcome the ground resistance torque on the armature (such as ground resistance torque and other load torque caused by friction), the armature can rotate counterclockwise.DC motor is a motor running on DC working voltage, which is widely used in tape recorders, video recorders, VCDs, hair dryers, electric razors, electronic watches and so on.
