Stator

A stator (also: stand, from Latin stare = stand still ) is called the fixed, non-moving part of a machine, particularly if there is also a rotor. For example, in an electric motor, generator, hydraulic motor or pump - in contrast to the moving part, the rotor (classic rotating) or the translator for a linear motor.

Electrical equipment

The stator is often also the case and consists of electric motors and generators, except for the constant field machinery, except for rare exceptions, had made ​​" of laminated steel ". He serves as common core for inductors. In contrast, the stator is the coreless motor and the rotor motor Ferrari partially within the hollow armature. When external rotor motor, the stator is completely inside of the rotor.

In electrostatic speakers (in short: " ESL " ) are referred to the fixed electrode grid as stators. In contrast to magnetostats the audio signal is not here at the sound-radiating membrane on, but the grid voltage is modulated. The membrane itself is under high constant voltage ( 1000-5000 volts) and occurs in electrodynamic interaction with the fields of the stators.

Compressor and turbine

In fluid power machinery such as ( axial) compressors and turbines is called a fixed stator vane ring. He directs the air flow low on the next blade ring.
