that is the stator of a ball mill

Stator - Wikipedia

The stator is the stationary part of a rotary system,[1] found in electric generators, electric motors, sirens, mud motors or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature; in a generator
