How does an Alternator Work ?

Alternators are the workhorse of the power generation industry. It is capable to generate AC power at a specified frequency. It is also called as synchronous generator. Electricity is produced in alternators by Electromagnetic Induction. To generate electricity in a coil, either the coil should rotate with respect to magnetic field or a magnetic field…

In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity. The moving parts in a machine can be rotating (rotating machines)…

Working of Synchronous Motor

As the name suggests, synchronous motors are capable of running at constant speed irrespective of the load acting on them. They are machines with high efficiency and are mainly used in high precision application. The constant speed characteristic is achieved by interaction between a constant and rotating magnetic field. Rotor of a synchronous motor produces…
