vahelduvvoolugeneraator

vahelduvvoolugeneraator is the Estonian term for an alternating current generator. An alternating current generator is an electrical machine that converts mechanical energy into electrical energy in the form of alternating current. This is achieved through the principle of electromagnetic induction, where a conductor moving within a magnetic field generates an electromotive force (voltage), which in turn drives a current.

The core components of a vahelduvvoolugeneraator typically include a rotor and a stator. The rotor is the rotating part, often carrying magnets or electromagnets, while the stator is the stationary part, usually containing coils of wire. As the rotor spins, its magnetic field interacts with the coils in the stator, inducing a voltage that periodically reverses its direction, thus creating alternating current.

Mechanical power to drive the rotor can come from various sources, such as steam turbines in power plants, internal combustion engines, wind turbines, or even hand cranks in smaller devices. The frequency of the alternating current produced is determined by the speed of rotation of the rotor and the number of magnetic poles. Vahelduvvoolugeneraatorid are fundamental to modern electrical power systems, supplying electricity to homes, industries, and transportation networks worldwide. They are the primary means of generating electricity in most power plants.
