Eddy Current Dynamometer

Overview

The Eddy Current Dynamometers offered by Dynomerk are advanced dry gap type rotor machines, available with single or twin rotors. These dynamometers possess inherent bi-directional operation capabilities.

One of the key advantages of our dry gap eddy current dynamometers is their exceptionally wide performance characteristics. They offer a broad speed range relative to power, making them suitable for both low and high-speed engines with similar maximum power requirements.

With a dry gap unit, the rotor’s movement is primarily opposed by bearing friction and minimal windage effects. By reducing excitation to zero, we can achieve nearly no-load conditions across the entire speed range. This unique characteristic has enabled us to meet diverse and increasingly stringent global standards mandated by legislation.
