The disadvantages of frequency control implementation on standard asynchronous electric motors
Annotation
The article discloses the structure and operation of variable frequency drives (VFD), is a block diagram of this drive, shows the influence of the rotation speed of the rotor of the electric motor from the pairs of poles, will give a General description of the conditions under which can provide frequency regulation. A comparison of a typical induction motor and engine, specially designed for frequency control. Marked disadvantages of the VFD.
