A stator is a stationary part of an electric machine, such as a motor or generator. It typically consists of coils of wire that create a magnetic field when electricity flows through them. This magnetic field interacts with the rotating part of the machine, known as the rotor, to produce motion or generate electricity. In many applications, the stator is crucial for the machine's efficiency and performance. It can be found in various devices, including electric vehicles, wind turbines, and industrial machinery. The design and materials used in the stator significantly affect the overall functionality of these machines.
