Working principle and schematic diagram of motor and generator
Motor is a kind of equipment that converts electrical energy into mechanical energy. It uses the electrified coil (stator winding) to generate a rotating magnetic field, which acts on the rotor (such as squirrel-cage closed aluminum frame) to form a magnetoelectric rotating torque. According to different power sources, motors are divided into DC motors and AC motors. The motors in the power system are mostly AC motors, which can be synchronous motors or asynchronous motors (the stator magnetic field speed of the motor is not synchronized with the rotor speed). The motor is mainly composed of stator and rotor, and the direction of electrified conductor in magnetic field is related to the direction of current and magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field acts on the current to make the motor rotate.

Generators are divided into diesel generators and gasoline generators. However, whether it is a diesel generator or a gasoline generator, the cylinders work in sequence according to a certain order, and the thrust acting on the piston becomes the force to push the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate. When the brushless synchronous alternator is coaxially installed with the crankshaft of the power machine, the rotor of the generator can be driven by the rotation of the power machine. The generator uses the principle of' electromagnetic induction' to output induced electromotive force and generate current through a closed load loop.
