Stator
As a stator (also: stand, from Latin stare = to stand still) is the fixed, immovable part of a device especially if there is also a rotor present. For example, in an electric motor, a generator, a hydraulic motor or a pump – in contrast to the moving part, the rotor (rotating in the conventional manner) or the translator of the linear motor.
Electrical device
The stator is often also the housing and in the case of electric motors and generators, with the exception of DC machines, always consists of “laminated steel“. It serves as a common core for the induction coils. In contrast to this, the bell-type armature motor and the Ferraris rotor motor, the stator is partially located within the hollow anchors. In the case of the external rotor motor, the stator is located completely within the rotor.
