gearless mill drive optical systems

  • Gearless mill drives Grinding ABB

    Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. The motor is fed by a fuse-less cycloconverter that is connected to the MV network through three special cycloconverter transformers.
