Re - Rolling mill motors
These types of motors have been designed basically for heavy duty use with driven machine imposing overloads and severe mechanical shocks and vibrations. These motors are equally suitable for smooth constant loads since the motors are also designed with high efficiency and power factor. Because of optimum utilization of materials, with improved ventilation techniques the motors are 10 - 15% lighter in weight and yet more rugged because of their inherent special construction.
Because of high pull out torque and inherent thermal margin kept for high slip operations these motors are ideally suited for re-rolling mills and ane cutter / cane crusher / care leveler / cane fiborizer applications pertaining to sugar industries, because of high efficiency and power factor these motors are also suitable for pump / fan applications.
