Roller mills are constructed of major mechanical components that can be easily damaged by high mill vibrations. It is very important that a mill is operated in a stable manner and that corrective actions are taken to prevent damage to mechanical equipment and mill outages that result in lost production. Unfortunately, high-vibration scenarios
Specific applications for such motors are rolling mills, rice mills, paper mills and cranes etc. for one or more of the following reasons 1. To contain the start-up inrush current, as a result of low start-up impedance and to control the same as needed through external resistance in the rotor circuit. 2. To provide a smoother start. 3
