101 BASICS SERIES STARTERS AND CONTACTORS - Newark

Welcome to Module 19, which is about starters, devices that control the use of electrical power to equipment, usually a motor. As the name implies, starters "start" motors. They can also stop them, reverse them, accelerate them, and protect them. Starters are made from two building blocks, contactors and overload protection:

Milling - Energy intensive and high maintenance - ABB

Squirrel cage induction motors are the most common motor used in the industry due to their versatility, reliability, robustness and simplicity. The maintenance is reduced to a minimum. Typically a 6 – 8 pole induction machine is used to turn the mill. The motors are generally forced cooled; this allows running the motor at very low

liquid rotor starters for slipring motors 550 to 20,000 kW

The EPM rotor starter is normally used to control the starting of a slipring motor, and the starting current is generally limit-ed to a maximum of 250% FLC. Optimal starting torque for each applica-tion is normally selected by the choice of the initial value of resistance. The principle of the EPM starter is that the

In order to limit the starting current of the motor, star-delta starting can be used for grid fed induction machines. The induction machine is started in star connection and later switched to delta connection. This reduces the starting peak current to one third (see Figure 9). However, the starting torque is also reduced to one third.

The overload protection device in the motor starter detects excessive over-current through the contactor's power control circuit. When an overload condition exists, the overload contacts in the lower power motor control circuit de-energize the contactor. The de-energized contactor opens the power control circuit, which removes power from the motor.
