Definition
- Noun:
- The stationary part of an electric motor or generator: The "stator" is the non-moving component that surrounds or is surrounded by the rotating part (the rotor). Its primary function is to provide a magnetic field or interact with the magnetic field of the rotor to produce motion or electricity.
Usage Examples
- Noun:
- The technician is inspecting the stator for any signs of damage.
- In an AC motor, the stator windings create a rotating magnetic field.
- A common fault in generators is a short circuit within the stator coils.
Advanced Usage
"Stator core": The laminated iron structure of the stator that supports the windings and provides a path for the magnetic flux.
- The stator core is made of thin steel sheets to reduce energy loss.
"Stator winding": The set of insulated wires or coils wound around the stator core that carry the electric current.
- The insulation on the stator winding must be able to withstand high temperatures.
Variants and Related Words
- Stator-rotor interaction (n): The electromagnetic interaction between the stationary stator and the rotating rotor that is fundamental to the operation of electric machines.
Synonyms
- Stationary part: A general term for any non-moving component, which can be used to describe the stator's function.
- Field winding: In some machine types (like DC machines), this term can refer to the windings on the stationary part that produce the main magnetic field, analogous to a stator's function.
Notes on Meaning
- The term "stator" is specific to electromechanical devices like motors, generators, and turbines. It is not used for purely mechanical devices.
- It is always contrasted with the rotor, which is the rotating part. The pair (stator and rotor) are essential components of any rotating electrical machine.
Noun
- mechanical device consisting of the stationary part of a motor or generator in or around which the rotor revolves
