High-tech for environment and controllers

At the heart of our innovative products is the EC technology integrated in the electric motors. EC stands for Electronically Commutated, the innovative commutation without wear-and-tear. The EC motor compares to the direct current shunt-wound motor but for the fact that the magnetic field is generated by permanent magnets inside the rotor.

You are no technician? No problem, for all you need to recognise the advantages this new technology offers is simple mathematics. Compared to conventional standard AC motors, our EC motors need an average of 30 % less energy – exceeding even 50 % in certain applications!

And what is more, they can be easily controlled, are maintenance-free, offer outstanding efficiency and have a considerably longer service life. On top of all this, the variable speed range possible in EC technology makes a multitude of individual models be a thing of the past, making your life a lot easier. Still, our R&D activities are not only focussed on saving energy. In terms of pressure build-up, air performance and low noise, our products meet toughest specifications.
