Generators are generally composed of stators, rotors, end covers, bearings and other components.
The main function of the stator is to generate a rotating magnetic field.
The main function of the rotor is to be cut by the magnetic lines in the rotating magnetic field to generate (output) a current.
The stator consists of the stator core, wire windings, machine base and other structural parts that secure these parts.
The rotor is composed of a rotor core winding (or magnetic pole, magnetic yoke), retaining ring, center ring, slip ring, a fan and a rotating shaft.
The stator and rotor of the generator are connected and assembled by the bearings and end covers, so that the rotor can rotate in the stator and carry out the cutting movement of the magnetic lines of force, generatethus having an induced effect. electric potential, which is discharged through the terminals and connected to the circuit, an electric current is generated.
Detailed information:
Generators are divided into: direct current generators and alternating current generators;
Alternating current generators are divided into: synchronous generators and asynchronous generators (rarely used);
Alternators can also be divided into single-phase generators and three-phase generators.
There are many types of generators. In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators. In terms of generation method, they are divided into steam turbine generators, hydraulic generators, diesel generators, gasoline generators, etc. In terms ofenergy, it is divided into thermal generators, hydraulic generators, etc.

The generator is mainly composed of rotor (magnetic pole), stator (armature), rectifier, voltage regulator, front and rear covers, brushes and brush holder.
1. Rotor
The function of the rotor is to generate a magnetic field. The rotor consists of claw poles, magnetic inductors, field windings, slip rings, rotor shafts, etc.
2. Stator
The stator is installed outside the rotor and secured with the front and rear covers of the generator. When the rotor rotates inside, Causes the magnetic flux in the stator winding to change and generates an alternating induced electromotive force in the stator winding.
3.Rectifier?
The function of the rectifier is to convert the three-phase alternating current from the stator winding into direct current. The rectifier consists of a rectifier plate and a rectifier diode.
4. Voltage regulator
The voltage regulator regulates the output voltage of the alternator.
5.Rear end cover
The end cover of the generator plays the role of fixing the rotor, stator, rectifier and broom.
The aluminum alloy cast generator end cover can effectively prevent magnetic flux leakage, and the aluminum alloy has good heat dissipation performance.
6. Brush and brush holder
The brush is an important component of the motor and is responsible for conducting current between rotating and stationary parts.
