YVF series vector dutys motor is an AC high-efficiency energy-saving speed regulating motor, which can be used with domestic and foreign frequency converters. The product has reliable operation and convenient maintenance. The motor is equipped with an axial flow fan alone, which has a good cooling effect at different speeds. The power, installation size and appearance of the motor are the same as those of the YE3 series three-phase asynchronous motor (the wind hood is slightly longer than the YE2 series).
