GreenTech innovations: That’s where the future lies!

GreenTech EC technology made by ebm-papst is the outstanding product of a consistent efficiency strategy. In technical terms, GreenTech EC technology can be referred to as “soft commutation”, representing as it does a combination of commutation strategy and motor design. The tangible result for customers is low-noise operation with no structure-borne noise. In other words, we employ various designs of permanent magnet motor to obtain the best possible performance for each application and for every power range required. Intelligent electronics provide compensation for synchronisation tolerances, leaving our customers to enjoy only the positive aspects.

The most significant advantage of fans and motors employing GreenTech EC technology as opposed to conventional asynchronous motors is that their efficiency level is up to 90 %. This means not only better utilization of primary energy, but also reduced heat loss and hence a longer service life.

The benefits in terms of efficiency are even more apparent in part load operation, as the integrated electronics of EC motors permit infinitely variable control. In this way the speed can always be adapted to the particular requirements. This feature offers added scope for potential savings in a variety of applications, whilst creating a more pleasant atmosphere – thanks to the greatly reduced noise levels for example.

Intelligent control and regulation functions are – alongside outstanding energy efficiency – some of the great benefits offered by ebm-papst GreenTech EC technology.

Fans can be controlled and monitored via MODBUS-RTU and/or 0–10 V / PWM, the parameters like speed, temperature of motor, operation and alarm display can be used for energy utilization optimization, load management and preventive maintenance etc.
