The overload protection of the asynchronous motor can prevent the increase of equipment damage due to excessive load.Three-phase asynchronous motorThere is an operating power, which we call the rated power, and if the actual power used in a certain situation exceeds the rated power we are also called overload.

       There will be a relay motor in the main circuit of the motor, which is the overload protector, whenThree-phase asynchronous motorOverload, it will produce action, normally closed contact will cut off the control circuit, normally open contact closed on the light; When the overload is eliminated, the contact of the thermal relay will be reset, so that the circuit will work happily, there are two ways of manual reset and automatic reset.

       The main symptoms of overload of three-phase asynchronous motor are: the increase of heat; The RPMS are down. They're even down to0; Accompanied by low chirping, but the vibration is generally not large; It may also be due to the drastic change of load, and the phenomenon of high and low speed.

       In actual production, the application of overload protection function can effectively prevent the safety risks caused by load overload.
