How AC Drives Can Save Money & Improve Your Power Factor

 

Hi, my name is Andy with Innovative-IDM. A lot of the time, when I’m out visiting customers, they have a variety of issues. One of the primary ones they have is: money. This money is basically due to, high energy cost from their utility company. And the main reason, this problem is occurring, is because their power factor is low.

Now, whenever we talk about power factor, really, what is it? Technically it is the ratio of the real power flowing to the load, to the apparent power in the circuit. Now, basically, all this is meaning is that, are you efficiently using the power coming in to your plant? Now, a lot of plants, back twenty, thirty, forty years ago were only using DC drives, DC motors, etc.

Now, these machines or these motors, these drives are inherently low on the power factor rating. Generally somewhere between 0 – 0.85 on the power factor rating. Now, An AC drive, for example, is usually between 0.85 and all the way up to 0.96 on the rating. What does this mean? AC drives are more efficient, they are extremely efficient in energy utilization compared to a DC motor or a DC drive.

Now, whenever you have, for example, a motor that’s running across the line with no drive at all, that power factor is directly related to the type of motor that it is, it’s duty cycle, etc. In general terms, putting a drive in front of a motor is always a good decision, because it will, more efficiently control the current traveling through that motor, end case is, savings.

Now, Yaskawa; for example, one of our manufactures of drives, actually provides a free download from our knowledge center at innovative-idm.com. Just click on knowledge center and you’ll find it. This energy savings predictor will allow you to input your motor, nameplate information, your drive name plate information and then, it’ll give you a graphical representation of, on average, what your power factor is, and how much you are capable to save. My suggestion to you is, to speak with your energy provider, as well as your local retrofit provider; Innovative-IDM and talk about how you can increase your power factor, thereby, saving more money.
