The working principle of the centrifugal switch is more special, and other switch products that play the role of control connection adjustment are different, you can see from the appearance alone, the following Xiaobian will take you to understand the working principle and function of the motor centrifugal switch.

First, the centrifugal switch working principle

The single-phase motor uses a rotor mounted on the motor, and the circuit is connected in series in the starting loop. When the rotor is stationary, the switch is on, and when it reaches a certain speed, the switch is off. The centrifugal switch is mainly used to control the starting coil of the single-phase motor.

Used by single-phase motors, mounted on the motor rotor, the circuit is connected in series in the starting loop. The switch is on when the rotor is stationary, and the switch is off when the rotor reaches a certain speed. When starting, the starting circuit starts through the centrifugal switch. When the centrifugal switch is off, the starting circuit is automatically cut off when the speed reaches a certain speed. When the starting ends, the motor becomes running.

The structure of centrifugal block is complicated, it is easy to fail, and even burn the auxiliary winding. And the switch is installed in the motor, the problem is not convenient maintenance. Therefore, the current single-phase asynchronous motors have less use of centrifugal switches as starting devices, and instead adopt various types of starting relays. The starting relay is generally installed on the motor housing, which is convenient for maintenance and inspection. Commonly used relays are voltage type, current type and differential type.

Second, what is the role of the centrifugal switch of the motor

When the motor is powered on, the starting winding and the starting capacitor are in parallel in the circuit to make the motor start at a low speed. When the motor speed reaches three-quarters of the normal speed, the centrifugal switch is forced to spring open, the starting winding exits, the running winding works, and the motor is started.

The working principle and function of the motor centrifugal switch are introduced here, more about the centrifugal switch related issues can pay attention to us, we will update more content regularly. If you need centrifugal switch, electronic centrifugal switch, all kinds of motor inverter, welcome to inquire.
