Three-phase alternator principle
Three-phase alternators are usually composed of stators, rotors, end caps, brushes, bases and bearings. The stator consists of a base, a stator core, a winding of the wire, and other structural components that secure these parts.
The principle of electromagnetic induction that induces a potential by cutting a magnetic line of a wire changes the mechanical energy of the prime mover into an electrical energy output. The synchronous generator consists of two parts, a stator and a rotor. The stator is an armature that emits electric power, and the rotor is a magnetic pole. The stator is composed of an armature core, a three-phase winding uniformly discharged, a base and an end cover. The rotor is usually a hidden pole type consisting of a field winding, a core and a shaft, a guard ring, a center ring, and the like. The number of poles of a steam turbine generator is mostly two poles, and there are also four poles.
Three-phase alternators are usually composed of stators, rotors, end caps, brushes, bases and bearings. The stator consists of a base, a stator core, a winding of the wire, and other structural components that secure these parts.
The rotor is composed of a rotor core, a rotor pole (having a magnetic pole. a magnetic pole winding), a slip ring, (also known as a copper ring. a collector ring), a fan and a rotating shaft.
The stator and the rotor of the generator are connected by bearings, the base and the end cover, so that the rotor can rotate in the stator, a certain excitation current is passed through the slip ring, the rotor becomes a rotating magnetic field, and the stator coil performs the movement of the cutting magnetic line. In order to generate an induced potential, which is drawn through the terminal and connected to the circuit, a current is generated.
