Generators are generally composed of stators, rotors, end covers, bearings and other components.
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.
There are many types of generators. In terms of energy, they are divided into thermal generators, hydraulic generators, etc. ; 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.
The operating principle isthat 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. , thus generating an induced electrical potential, which crosses the terminals. When removed and connected in the loop, a current is generated.
