YVF2 series motor can be used in inverter, which is a typical motor of energy-saving, advancedelectromagnetic calculation and special insulation system ensure the motor fits for the inverterpower supply system. in general the rated voltage is 380V,frequency is 50Hz, constanttorque with frequency 5(3)~50Hz, constant output with frequency 50 ~ 100Hz. The voltage andfreguency of the rated point can be ensured according to the customers’requirement, and Yconnection can be used if theframe size is 250 and below. Above 250 isAconnection, and thecooling method can be lC411 or lC611.
