Is an EC motor more energy efficient than an AC motor? | What The Tech?!

When we compare an electronically commutated EC motor with an electric motor driven by an alternating current (AC) one thing becomes evident: The EC motor has a greater energy-saving potential. An EC motor in combination with a fan has a higher efficiency level, safes energy and protects the environment.
Let's compare a light bulb and a modern LED. The LED saves 90 percent in terms of energy, which is good for the environment, and good for your wallet. The same applies to electric motors in fans. With the same air performance, the EC fan is not only more compact and lighter - its higher efficiency level makes it much more efficient than the AC fan. Its true energy-saving potential can be seen when several fans work together. AC fans usually have two states: on and off. If you want less air flow, you have to deactivate a few fans. EC fans are infinitely adjustable. If you want less air flow, you can run all the fans more slowly. And this is where the magic happens. Let's say we want 50 percent air flow. We switch off half of the AC fans and save half the energy. We control the EC fans at half speed. And since fans consume exponentially more energy under top load, we can thereby save 87 percent of the energy. Almost as much as with the LED bulb.
And, as with the LED, the higher procurement costs pay for themselves in a short time.
That's why, if you want to save, you should change over to modern EC fans - and you can play your part in protecting the environment at the same time.

EC Fans are the future of HVAC

Indeed

"It's higher efficiency makes it much more efficient."
Huh.

You could, say, explain what you mean with EC fan end EC motor. Because it honestly sounds to me a lot like you're talking about a DC motor. This is so vague it's not really useful.

Hi Lua 🙂 Thanks for your comment. An EC motor works with DC and is different in the electrical commutation - the exact explanation can be found here:
