A soft starter is a thyristor voltage controller to smoothly ramp up the voltage at the motor terminals. Soft starters use a controller that allows a timed ramp of output voltage and current limit. When the soft starter reaches full voltage, the bypass contactor closes. The available motor torque, is proportional to the square of the voltage.

The motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?

In many cases, a motor labeled as "severe duty" falls between a standard TEFC motor and an IEEE 841 rated motor. A totally enclosed fan-cooled (TEFC) motor has a frame that prevents air exchange between the inside and outside of the motor, preventing airborne contamination — and to some extent, liquids — from entering the motor.

MOTOR AC synchronous motors are used for driving the roughing stand rolls in a rolling mill. Synchronous motors are used when power requirement is very high and speed of rolling is low. The R0/V0 stand motors of Hot Strip Mill of Rourkela Steel Plant are synchronous motor. These motors are driven by cyclo converter.

Each mills have two motors of 8000 kW at 13.8 kV. A: For large mills requiring variable speed, the wound rotor motor and SER drive are economical for a total rating of approximately 2MW to 16MW. Above 16MW, the gearless drive (cyclo-converter) is typically used because gearboxes and pinion gears reach their present limit in size.
