1. AC Induction Asynchronous Motor. The majority of motors used in industries are three-phase AC motors. Since these motors are highly-reliable and of low cost, they are the preferred choice for industrial applications. The electric current in the stator generates a rotating magnetic field that induces an electric current in the rotor.

Rolling Mill Motors Used in the steel and aluminum industries, rolling mill motors generally operate at low speeds and are designed for constant torque with a speed range of up to four to one. Some applications include continuous cold mills, continuous hot strip mills, and reversing hot mills.
III. AC DRIVE FOR ROLLING STAND 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.
