NFO Drives Frequency Inverter

Speed control of three-phase asynchronous motors. Patented technology provides an output voltage in the form of pure sine wave. EMC: interference free - no need for filters (RFI, motor choke, sinus filter). Installation with unshielded cable approved. Existing cable can normally be used. Unlimited cable distance between inverter and motor. Quiet - no switching noise from the motor. No ground currents - maximum of 2 mA. Residual current device (30 mA) can be used. No bearing currents - causes no bearing damage. 5 year warranty on ball bearings. Full torque at all engine speeds - even from a standstill. MODBUS integrated.
