To start there are many things that variable frequency drives are called, a few of the popular ones include:
VFD (variable frequency drive), adjustable frequency drives, inverters, phase converters, variable speed drives, speed control drive and AC drives
Basically what all of these VFD'S do is vary the speed of industrial electric motors. Variable frequency drives can do more than just speed control, they can also convert single phase into three phase power.
From home hobbyists running a lathe or milling machine to high tech automated factory lines, high performance AC drives have their place in your application.
