Brief Introduction

Variable frequency speed regulation motors follow Chinese standard, GB755-2008 Rotating electrical machines-Rating and performance , which equals to IEC60034-1:2004.

The so-called variable frequency speed regulation motor mainly refers to an efficient motor that is suitable for being powered by a frequency converter. The motor can achieve different speeds and torques under the drive of a frequency converter to adapt to changes in load demand. Variable frequency motors have evolved from traditional squirrel cage motors, replacing traditional motor fans with independent fans and improving the insulation performance of motor windings.

With the increasingly widespread application of frequency converters in the field of industrial control, the use of YVF2 series vfd blower motor is also becoming more and more widespread. It can be said that due to the superiority of variable frequency motors over ordinary motors in frequency control, we can easily see the presence of variable frequency motors wherever frequency converters are used.

From motors' outlook, there will be one obvious difference compared with normal AC motor. On the fan cover of motor NDE side, there will be one extra junction box, in which there will be cables for connection separate fan motor. Here is one chart for fan motor parameters.

In order to meet the needs of variable frequency speed control systems, novel electric motors continue to emerge, characterized by breaking away from the concept of conventional rotating magnetic fields and utilizing the mechanism of magnetic field deformation generated by the combination of motor structure and control to drive rotor rotation.
