VMF Series

The VFM series variable frequency three-phase asynchronous motor is a fullyenclosed independent cooling fan structured motor produced by our company.The frequency converter can achieve stepless speed regulation of the power supply.achieving the purpose of energy conservation and automation control. lt is currentlyone of the advanced AC speed regulation systems, and its power and installation sizecomply with lEC standards. lt is the same as the EM2 series three-phase asynchronousmotor and can be matched with various SPWM frequency conversion devices athome and abroad.

Product Features

1) The novel style of the junction box, base, end cover, and fan cover is conducive to noisereduction and ventilation

2) The motor adopts a thermal rating of 155 (F)insulation system to extend its service life

3) The working system is S1, the cooling method lC411, and the shell protection level lP55 or lP56

4) lt bears excellent starting characteristics.

5) lt features low temperature rise, high reliability, high efficiency, strong energy conservation,good safety, strong environmental protection, and nice appearance.

6) lt also features high speed regulation accuracy, wide speed regulation range, low vibration.and easy to achieve various automatic controls.
