YVF2 series (IP54) frequency-variable speed-regulation three-phase asynchronous motor is the latest unily design in our country, which is derived from Y2 series (IP54). It not only looks beautihul and dignified, but also has low noise and weak vibration. it has wide scope regulate and it is so steady that has no class, This motor has independent and well ventlated cooling system, and can run at low speed over a long time. It is matched with all transducer, have the fast dynamic responding with vector control mode, no torque wave at low speed and no resonance. This series motor frame number is from 80 to 355, total 13 frame numbers and 30 specifications. At present, our factory produce motor at the frame number from 80 to 280, totaly 11 frame numbers and 23 speclfications. This series motor is made according to the JB/T7118-2014 《The technical condlitions for YVF2 series (lP54) frequency-varlable speed-regulation three-phase asynchronous motor》 . We can also produce YVF,EJ seres frequency-varable speed-regulation electromagnetic brake three-phase asynchronous motor.
