Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, 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 mill shell. Drive motors In the case of ring gear drives, either wound rotor induction motors or synchronous motors can be used. Induction motors Wound rotor induction motors are usually equipped with starters for a controlled ramp up of mill speed with modest inrush currents. Motor speeds usually require the application of a speed reducer.
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor''s rotor can be either wound type or squirrelcage type.
answered. Depending on the mill size and type, the mill can be driven by several configurations of drive systems. The main options are single low speed motors connected to a pinion driving a ring gear, two low speed motors connected to two pinions and driving a ring gear, or a gearless motor mounted directly onto the mill. In addition, a gearbox
