The optimum motor control

NFO Drives develops frequency inverters with a unique patented technology used for motor control of electric motors. The company's technology differs from all other manufacturers in the following way: NFO Sinus reshapes the frequency of the sine curve while maintaining a pure sine curve. The main argument for choosing NFO frequency inverters is reduction of bearing damage due to the fact that the patented technology creates no bearing currents, which in turn means cost-effective, uninterrupted operation of motors.

A profitable investment

With the NFO Sinus frequency inverter you can control the speed of electrical motors for machines, fans and pumps and save energy. An investment often pays for itself within a year.

Product range

NFO comes in the following power ratings and housings:

Choose correct Inverter, Contact NFO Drives!

Choose the correct inverter dimension for the motor to be controlled: Read the motor’s nominal current from its rating plate and choose an inverter that is able to supply this current on a continously basis.

An NFO inverter can be used to control several motors by ensuring there is sufficient current.

Example: To control three motors with a nominal current of 2.1 A (6.3 A in total), choose a 3.0 kW inverter with a continuous discharge current of 6.7 A.
A smaller inverter can be chosen if you know that the motor will not be running at full current.
If you want to be able to load the motor above its nominal current, take this into consideration when choosing an inverter.
