Under the same load by artificial way to change the speed of the motor, we will call this is speed regulation. todayThree-phase asynchronous motor manufacturersMori machineXiaobian will take you to understand how to speed regulate the motor, and what are the ways.

       There are three ways to change the speed of the motor, namely: frequency conversion speed regulation, pole change speed regulation and cascade speed regulation. We knowN=60*f/P,NIs the speed of rotation,60Is per minute (second); Then we just have to changefwithPThese two values,NIt will change.

       Here, let's talk about frequency conversion speed regulation . Variable frequency speed regulation of three-phase asynchronous motor refers to changing the motor speed by changing the frequency of the power supply. It uses a set of special frequency converter to change the frequency of the power supply to achieve variable frequency speed regulation. The frequency converter itself is more expensive, But it can achieve smoother stepless speed regulation in a large range, And has hard mechanical properties, It is an ideal speed regulation method. In recent years, With the development of power electronics technology, Ac motor speed regulation in this way is more and more common.

Frequency conversion speed regulation: by changing the frequency (50HZ), when the frequencyfhigherNThe higher the magnetic field speed, the higher the rotor speed.
