YVF2 series is derivative from Y2 series so the frame NO. and installation size corresponding to the same power are consistent with Y2 series, but the overall shape is appropriately longer. The motor is equipped with a separate axial fan as the cooling air source to ensure the temperature rise of the motor at low frequencies. The motor can be matched with various kinds of frequency conversion equipment at home and abroad, and its constituting speed control system is characterized by remarkable energy conservation, wide speed range, strong overload capability and excellent low-speed performance. It is extensively used in metallurgy, mining, petrochemical, textile, light industry and paper-making industry, etc.
