Weg (Marathon) SPDP Motor

Overview

The type RW 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 operation these motors are ideally suited for rerolling mills and cane cutter/cane crusher/care leveller/cane fiborizer applications pertaining to sugar industries. Because of high efficiency and power factor these mtors are also suitable for pump/fan applications.
