The optimum motor control
NFO Sinus is the obvious choice for motor control of electric motors. As the only product on the market, NFO Sinus transforms the frequency of the sine curve while maintaining a pure sine curve. This technology allows you to reduce bearing damage as no bearing currents occur. This in turn means cost-effective, uninterrupted operation of engines. At the same time, the motor can be operated quietly and without the need for expensive shielded cables. Overall, this makes the NFO inverter a profitable investment that often pays-off within 1 year. In addition he low energy consumption helps you reach your sustainability goals.
