YVP series variable-frequency speed control specia

Overview YVP series variable-frequency speed control special three-phase asynchoronous motor with converter plant form speed control system, compared with the other speed control, evident effect of energy saving good, speed regulating performance, wide speed range, with low noise, little vibration. It can be widely used in light industry, textile, chemical industry, metallurgy, machine tools, etc. where speed control by constant power ,constant torque and fans, pumps and other energy-saving speed control, to realize automation control of speed control system. Conditions of Usage: Height above sea level≤1000m;Ambient air humidity changes with the seasons change,.but it does not exceed 40centi degree.Minimum not more than -15centi degree.Wettest monthly mean relative humidity was 90%, while the monthly average minimum temperature of no higher than 25 centi degree.. Structural Shape Protection Grade: IP44/IP54Cooling way IC416According to user requirements can take a variety of high-resolution sensors (photoelectric encoder, rotary transformers and speed generator)Depends from the shaft extension, electrical junction box located on the right seat, In accordance with user requirements can also be located on the left or top of the seat. Main technical performance The motor will operate continuously.Rated voltage 380V, rated frequency is 50Hz. It can also be required to determine the voltage and frequency Insulation Grade :FCenter height 80-255, constant torque speed 5-50Hz , Center height 250-355 , constant torque speed.3 --- 50Hz ,constant power speed 50 -100Hz ,it Can also determine the frequency range according to user requirements. Strong overload Low-speed performance is good Frame sizes 280 and 280 below for the Y connection,315-355 for thetriangleconnection
