What is a drive?

The driver is also called a frequency controller, and the speed of the motor is controlled by adjusting the rotation speed (speed) of the rotating shaft of the motor. As the frequency increases, the motor shaft (rotor) rotates faster. On the contrary, the frequency is reduced, that is, the motor shaft (rotor) rotates more slowly. UNIS Group specializes in repairing inverters, servo drives and soft starters.
