Without a starting resistor the rotor current would reach up to 7 x rated current which would negatively influence the supply grids. Further it is possible to generate a smoother starting curve which protects electrical as well as mechanical components of the application and the motor and assures a smooth startup of the system.

Ore grinding mills are really just slowly rotating barrels, but barrels that are growing in size so fast that the application of electric drives for them is rapidly approaching a technology like that for wind tunnels or pumped storage drives. This application is particularly worthy of care because some 40% of the 75 megawatts of power used by a ...
Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% …
Typically, the three points on the curve of most interest would be the rated full-load torque (and speed), the starting or locked rotor torque, and the break-down torque. From the curve of Figure 2, it is seen that this motor develops its rated horsepower at 588 RPM, or just two percent slip.
For example, If the stator full load current was 250A (not sure what it is in this case) and the Stator start current was 400A (1.6x) then I would expect Rotor start current to be 1.6 x Rotor full load current = 775 x 1.6 = 1240A. Torque delivered would be around 1.6 x Full load torque, very typical for a ball mill or sag mill as Chris mentioned.

Ours is 4160v and the stator induces the rotor to about 1500vac through a slip ring to the resistor bank. The motor starts with all resistors in parallel, each contactor "step" has a contact in an oil bath to each resistor bank, each step takes like 5 seconds until all the resistors have been removed and the rotor is shorted.
mainly applied grinding ball mill motor starting curves. Grinding Mills Ball Mill Rod Mill Design Parts 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 1 An induction motor can therefore be made without …

motor, it has associated complications on a wound rotor induction motor, especially if driving a grinding mill. A locked rotor condition has been found more commonly at Mill Safe Start sites than would have been suspected, due to problems with barring/inching gear interlocks or main gear problems. Without the Mill Jammed protection, the

Wound-Rotor Motors The wound-rotor motors are normally used in loads with high inertia or high resistive torque at startup. They are also used when starting current limitations are present in the power supply system. They are used to drive loads such as: ball mills, cement mills, fans, exhaust fans,...

In wound rotor motors, the rotor is "wound" with wire similar to the stator, with their terminal ends connected to 3 slip rings on the output shaft. These slip rings are attached to brushes and variable power resistor banks, where operators can change the speed of the motor by varying the resistance through the rotor coils.
Without a starting resistor the starting rotor current would reach up to 7 x rated current which would neg-atively influence the supply grids. Further it is possible to generate a smoother starting curve which protects electrical as well as mechanical components of the application and the motor and assures a smooth startup of the system.
