What is the primary function of a motor starter?

Explanation:
A motor starter is designed to start and protect electric motors. When a motor starts, it draws a large inrush current that can stress electrical circuits and cause voltage dips or overheating. The starter provides a controlled way to apply power using a contactor to switch the heavy motor current, and an overload protection device to monitor current (and often temperature) and interrupt power if the motor is overloading. This combination lets you safely start, stop, and automatically control a motor while guarding it against damage from overloads or faults. It’s not about reducing friction, encoding rotation, or controlling lighting.
