Highly efficient fans with highly efficient drive technology

The entire range with new drive
The entire product line of direct driven fans by Nicotra Gebhardt is now available with the particularly energy efficient brushless DC technology. These innovative motors achieve the highest efficiency and therefore cost less to operate than traditional
AC motors in every application.

Fit for the future with brushless DCs
The EU’s ErP Directive prescribes minimum levels of efficiency for electric motors. These levels of efficiency will be steadily increased in the coming years. Motors with brushless DC drives already exceed the requirements that will become compulsory in 2015 and 2017.

Why brushless DCs are effective

Higher efficiency
Brushless DC motors achieve significantly higher efficiencies than AC motors in all load ranges. Up to 50 % energy can be saved in partial loads.
Lower losses
Brushless DC motors work without slip. This results in significantly lower losses than when using induction motors.
Electrical energy is fully converted into torque
The supplied electrical energy is fully converted into available torque through the use of permanent magnets.
Harmonised control electronics
An electronic control takes over the speed control and regulation. The motor and the electronic control form one harmonised, coherent unit.
Higher power densities
The power densities of brushless DC motors are markedly higher than that of AC motors. This is why the size of the unit is smaller with the same output.
Improves system efficiency of fans
Due to their high efficiency, drives with brushless DC motors lastingly improve system efficiencies of fans and in this way assist in meeting the ever more stringent legal requirements.
