China 750 DC motor, DC motor refers to a rotating motor that can convert dc electric energy into mechanical energy (DC motor) or mechanical energy into DC electric energy (DC generator). It is a motor that can realize the conversion of direct current energy and mechanical energy. When it runs as a motor, it is a direct current motor, which converts electrical energy into mechanical energy. When the generator is running, it is a dc generator, which converts mechanical energy into electrical energy.
The working principle of the DC generator is that the induced alternating electromotive force in the armature coil is changed into the direct current electromotive force by the commutator with the commutation of the brush when it is led out from the brush end.
The direction of the induction electromotive force is determined by the right hand rule (the magnetic induction line points to the palm of the hand, the thumb points to the direction of the conductor's movement, and the other four fingers point to the direction of the induction electromotive force in the conductor).
