Dynamometer

Range: 10 nm to 5000 nm

A precise, low-maintenance, rapid response, and repeatable alternative to water brake technology, Aarohi’s Eddy Current Dynos provide low-inertia, air- or water-cooled operation for testing motors up to 720KW

This style of dynamometer produces braking torque using the principle of eddy currents induced in a rotating metallic disk, immersed in a magnetic field. A strain gauge load cell on all models provides torque measurement capabilities for precise test and development applications. The rugged design of the power absorbing system – further enhanced by nickel plating of critical components in contact with the cooling water – ensures a long operating life, even in the most demanding applications and environments.
