Synchronigeneraattorit

Synchronigeneraattorit, often referred to as alternators, are a type of electrical generator that produces alternating current. Their operation is based on the principle of electromagnetic induction. A rotor, which is an electromagnet, rotates within a stationary stator, which contains coils of wire. The rotating magnetic field of the rotor induces a voltage in the stator coils, creating an alternating current. The speed of rotation of the rotor directly determines the frequency of the generated electricity. Synchronous generators are widely used in power plants for electricity generation because they can produce a stable and controllable output. They are also crucial components in vehicles, where they are used to recharge the battery and power the electrical systems. The synchronous nature refers to the fact that the rotor's speed is synchronized with the frequency of the electrical grid it is connected to. This synchronization is maintained by the interaction between the magnetic field of the rotor and the magnetic field produced by the stator currents. Control systems are employed to adjust the excitation of the rotor's magnetic field and the prime mover's speed to ensure stable operation and power factor correction.
