YVF2 variable frequency adjusting speed three phase asynchronous motor use converter as power supply . The speed is smoothly adjusted by changing the power frequency to realize saving energy and automatic control purpose.

YVF2 series have advantages as high efficiency, wide speed range, high precision, stable running, convenient operation and maintenance. The outline and Installation dimensions confirm to IEC standard. Enclosure protection degree IP55, equipped with enforced cooling fan, work duty S1, insulation Class F , rated voltage 380V, rated frequency 50HZ. It runs with constant torque at frequency 3HZ-50HZ, and 2 poles electric motors run with constant power at frequency 50-60HZ, 4 poles and 6 poles  electric motors run with constant power at frequency 50-100HZ.

YVF2 series Can be widely used in dry CNC machine tool spindle drive, textile, chemical, metallurgical and other industries for constant torque, constant power speed regulation, as well as fans and pumps, and other occasions of energy-saving speed regulation.
