5. Hard start of mill motor, throwing ball charge. Most mills are designed with a soft starter arrangement; a typical mill starter system could include a Liquid Resistor Soft Starter (LRS) or Variable Frequency Drive (VFD), or it could be a clutch. Regardless of the system used, it is important to use
motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build-up generated during motor start-up. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances.
