Can the motor be used as a generator?

The electric motor can be used as a generator.

The principle of the method is as follows:

A three-phase asynchronous motor can generate electricity. When the three-phase asynchronous motor is connected to the grid, it will generate electricity if the speed is greater than the synchronous speed; when the three-phase asynchronous motor operates independently, it must be connected in parallel with a capacitor and the prime mover drags it to a certain speed before it can generate electricity.

The working principle of a three-phase asynchronous motor is as follows:

When the three-phase stator windings of the motor (each phase differs by 120 degrees in electrical angle) are supplied with three-phase symmetrical alternating current, a The rotating magnetic field cuts the rotor winding, thereby generating an induced current in the rotor winding (the rotor winding is a closed path). The current-carrying rotor conductor will generate electromagnetic force under the action of the stator rotating magnetic field, thus forming an electromagnetic rotation on the motor shaft. Torque drives the motor to rotate, and the direction of motor rotation is the same as the direction of the rotating magnetic field.
