Industrial control automation capacitive contactor: analysis of principle and function

Capacitive contactor in industrial automation, do you know its function and principle? Let’s talk about this topic today.

The capacitive contactor in industrial automation is an important device used to control the starting and stopping of electric motors.

Its working principle is to control the pull-in and disconnection of the contactor by changing the voltage of the contactor coil, thereby controlling the start and stop of the motor.

Capacitive contactors usually consist of a static contact and a movable contact.

When the coil of the contactor is energized, an attractive force will be generated between the static contact and the movable contact, causing the movable contact to attract the static contact.

This turns on the power to the motor. When the contactor's coil is de-energized, the attractive force disappears and the spring pulls the moving contacts apart, disconnecting power from the motor.

In industrial automation, the role of capacitive contactors is very important.

It can quickly start and stop the motor and improve production efficiency and product quality.

By understanding the working principle and function of capacitive contactors, we can better understand and use it and improve production efficiency and product quality.
