What is EC technology?

EC fans consume, on average, about 30% less electricity than conventional AC fans but what is an EC fan and what makes it more efficient?

EC stands for Electronically Commutated which means it’s a fan with a permanent magnet motor (PMM).  EC motors have been around for many years and are more efficient than AC motors because they use permanent magnets rather than induce a secondary magnetic field in the rotor.

Since 1995, ebm-papst has pioneered the development of EC fans, which can be connected directly to an AC mains supply rather than a separate DC power supply, making them easy to substitute for inefficient AC fans.

Benefits over traditional fan technology:

Reduced Energy Consumption
Significant noise reduction
Intelligent electronic control
No need for additional motor protection
Remote monitoring via ModBus
