Motor relay

A motor relay is an electrical component used to control the operation of an electric motor or motor. It usually consists of an electromagnetic relay and a switching circuit used to control the motor.

The working principle of the motor relay is to control the switch of the motor by using the electromagnetic attraction and release characteristics of the electromagnetic relay. When the current in the control circuit passes through the coil of the electromagnetic relay, the iron core of the electromagnetic relay will be attracted by the magnetic force, making the contact of the relay close, so that the motor is energized. When the current in the control circuit stops flowing, the coil of the electromagnetic relay loses its electromagnetic attraction, and the contact opens, stopping the motor.

Motor relays are widely used in various motor control systems, such as industrial automation equipment, elevators, air conditioners, electric vehicles and so on. It has the characteristics of easy control, high reliability, long life and so on, and can effectively protect the motor from overcurrent, overload and other faults.
