Eddy Current Dynamometers

Complete line of eddy current dynamometers from five to four thousand horsepower is available from Midwest and Dynamatic DynamometersEddy Current Models from 5 to 4000 hp

Eddy Current Dynamometer Technology

An Eddy Current absorption dynamometer produces braking torque using the principle of eddy currents induced in a rotating metallic disk, immersed in a magnetic field. It is basically an eddy current brake mounted in trunnion bearings. Its advantages are maintenance, control, simple construction and desirable speed-torque characteristics. The speed-torque characteristics make the eddy current dynamometer ideal for engine testing, and its versatility also allows effective use in testing transmissions, turbines, electric motors, gears, pumps and many other machines.

New Dynamometer Manufacturing: Two Complementary Eddy Current Lines

Whatever the application, there is probably a Midwest or Dynamatic model that fits your requirements and will give many years of dependable service. The wide range of Midwest and Dynamatic eddy current dynamometer models can often be further customized for an even better fit with your application. In general, look at Midwest models for higher inertia applications, and Dynamatic models if your application requires lower inertia and higher speed.

Factory Warranty

All new Midwest and Dynamatic eddy current dynamometers come with a 2-year factory warranty. Remanufactured units receive one full year factory warranty as a measure of our confidence in the Midwest-Dynamatic OEM remanufacturing process.

Benefits of OEM Dynamometer Remanufacturing

Your company's ISO Certification may be adversely affected if your dynamometer is rebuilt by a non-OEM shop. As the OEM for Midwest and Dynamatic eddy current dynos, our remanufacturing process returns these units to a “like new” status and makes them fully compliant to OEM specifications. You know your dyno is repaired right when serviced by Midwest-Dynamatic.

Used Eddy Current Dynamometers

For a cost-saving option, check our inventory of pre-owned eddy current (and AC and DC) dynamometers that are ready to be remanufactured. We may have the unit that is right for your application.
