An electrical machine is a device capable of transforming

From a mechanical perspective, electrical machines can be classified as rotating and static. Rotating machines are provided with rotating parts, such as dynamos, alternators, motors. Static machines do not have moving parts, such as transformers. In rotating machines, there is a fixed part called the stator or stator and a moving part called the rotor . The rotor usually rotates inside the stator. The air space between the two is called the air gap . Electric motors and generators are the simplest example of a rotating machine. From a mechanical perspective, electrical machines can be classified as rotating and static.
