Assembly, operating method and circuit for a mill driven by a ring motor

摘要: An assembly is provided for receiving characteristic data of a mill including rotating sleeve having rotor coils and stator coils, wherein oscillations the are transmitted to and/or measurement on stator. The may include coil(s) configured tap power supply induction voltages detect sleeve, designed positioned in sector which large expected based scale sleeve. Further, method includes determining voltage induced by tapping at least one coil coil, deriving status variable(s) milling that reflect fill level respective coil.
