AC Variable Frequency Drives

The easiest way to learn all about AC Variable Frequency Drives and get Certified

Are you interested in knowing more about AC Variable Frequency Drives (known as VFDs for short) ? VFDs are also referred to as Variable Speed Drives, AC Drives, Inverter Drives, Frequency Drives, Adjustable Speed Drives and other similar terms.

VFDs are growing in importance every day. You see them being increasingly used in all kinds of places, not just manufacturing plants and industries, but also in office buildings, warehouses and other commercial places. The reason is easy. They are the best thing that ever happened to the ac induction motor, as you can now control these motors in a variety of ways, which were not at all possible earlier. For years together, the ac induction motor, the workhorse of all manufacturing as well as all kinds of activity of any kind, was labeled as a "constant speed machine". But with the advent of this new technology, we could easily adjust speed as well as other parameters of these motors easily.

However, the information that is available on how to use these drives is not very easily available. Of course there ARE several sources of information, but are problematic. Why? Read on below:

Source 1: The internet

Of course, there is a lot of "free information" out there that is on the internet, but it is difficult to verify, collate and understand. To do this would also require literally spending endless hours surfing, and trying to find something that can actually be used in your work. What is your time worth? Multiply that by the hours that you would have to spend collecting all this information. Also some of this information may be incorrect as well as outdated. You also don't get a Certificate for your labors.

Source 2: Textbooks

You could buy a textbook on the subject from any of the bookstores; the only problems being that the information is very likely outdated and secondly many of these are written in a way that is difficult to understand for the practising engineer or technician like you. Seriously do you have the time to solve some complex vector mathematics, differential equations and the like? Or would you want to find out quickly how to select and use a commercially available VFD for your application? No Certificate gets issued if you read the book.

Source 3: Vendor literature & training courses

Would you ask a barber whether you need a haircut? What would be the answer? No prizes for guessing! If you ask a vendor (nothing against them, they are the ones who develop the technology behind these wonderful devices), the chances are that you will not get UNBIASED answers. Suppose a standard V/f drive is good enough for your application. Would a typical vendor tell you that? Or would he/she try to "upsell" you to a more advanced one? I think you get the point....
Vendor specific training programs will cover only the models and types of VFDs that the vendor sells.

So, we at Abhisam Software (who develop a lot of e-learning courses for engineers and technicians) thought about it and decided that we should have an UNBIASED, VENDOR NEUTRAL, COMPLETE  TRAINING COURSE WITH CERTIFICATION about this wonderful technology which is also

a) Easy to understand with graphics and animations to explain key concepts

b) Having a complete, unbiased and current vendor neutral information

c) Not too long winded and boring, without skipping anything important

d) Easily accessible- Either download it to your PC/laptop or access it online based on the version that you select

d) Having an associated exam and Certification with an electronic badge- display your competence to the world!

So we decided to make this software based training program for it,  which we call an XPRTU. (It makes and expert out of you).
