What is a drive?

A drive, also called a frequency converter or frequency drive, is used to control the speed of an electric motor. You can regulate the axle revolutions (the speed) of a motor using a frequency drive. When you increase the frequency, the axis (rotor) of the motor will run faster. Conversely, if you lower the frequency, the axis (rotor) of the motor will spin slower. UNIS Group specializes in repairing frequency drives, servo drives and softstarters.

What is a drive used for?

A frequency drive is now used in many industrial sectors. The drive is for instance used in controlling the speed of conveyor belts and fans, in hoisting and in pumps, as well as in the processing of various materials such as wood and metal, where variable speed is important. It is possible to vary this speed using a drive.
