Brief introduction: 

      YVF series variable frequency adjustable-speed converter-fed three phase induction motor is a kind of special motor which driven by frequency converter, rotating speed of the YVF series three phase electric motors can be regulated steplessly by frequency converter, thus enable energy saving and automatic control of the motors. YVF series electric motors are fitted with ventilation fan which provide better cooling effect to ensure motors running at various speed. To be convenient for users, dimensions and rated output of YVF series electric motors are same as those of Y series electric motors, also in conformity with  IEC 60072-1:1991.

       YVF series three phase induction motors are suitable for transmissions by which speed-regulation is needed, are widely used in light industries, metallurgy industries, textile industries, chemical industries, machine tool industries etc. while fitted with highly accurate sensor, the motors can achieve highly accurate operation of closed loop.
