Tips: How does a magnetic motor starter work?

A magnetic motor starter operates by controlling the electrical power supply to an electric motor. It consists of two main components: a contactor and an overload relay. When the motor is to be started, a start button is pressed, sending a signal to the magnetic motor starter. The contactor, an electromagnetic switch, is energized by a coil. As the coil receives power, it creates a magnetic field that attracts the contactor's movable armature, closing the contacts and allowing electrical current to flow from the power source to the motor.

Simultaneously, the overload relay monitors the current drawn by the motor. If the current exceeds a predetermined threshold, indicating a potential overload or fault, the overload relay trips, opening the circuit and disconnecting power to the motor. This serves to protect the motor from overheating and potential damage.

The combination of the contactor for motor power control and the overload relay for motor protection makes the magnetic motor starter a crucial component in ensuring the safe and efficient operation of electric motors in various industrial and commercial applications.
