AC Inverters Will Save You Money!

Cost hikes by suppliers of energy are just not stopping, in fact recently all the main suppliers have put their prices up, and the latest reports suggest that by the end of the year, most energy bills will go up again.

Fitting AC Inverters to three phase motors is not new news, and people already know that an Inverter can save energy. However, most people are still surprised by just how much money they could be saving by reducing the speed of their motors, whether it be a one large motor or lots of smaller ones.

To get a rough indication of any saving, the maths is actually very simple.
As it is a cube law curve then any reduction in speed will have the cube affect on the load!
ie. if the running speed is 90% then the middle part of the equation below is
0.9 cubed so 0.9x0.9x0.9 = 0.729

So for example, if you can reduce the speed to 90% (therefore 0.9),
then just simply say (1-(0.9x0.9x0.9))*100 = 27.1% Energy Saving.

So imagine if you could reduce to about 80% (0.8)
then it would be (1-(0.8x0.8x0.8))*100 = 48.8% Energy Saving!

Obviously this is purely a rough guide as this doesn't take into account any efficiency
issues of the motor etc but it is a good rule of thumb.

Also you must consider that by fitting an AC Inverter you have a soft start facility, so no large starting currents and you can therefore even switch it off at certain times without any re-starting issues. This will help with the motor and mechanical system giving long life.

Whether you have just one fan or pump or a complete factory with multiple HVAC fans,
the savings can be amazing.
