Eddy Current Dynamometers (Dynos) Providing Precise Control and Low Maintenance
Our eddy current dynos are simple, cost effective, torque measuring devices for a large range of test purposes. They are available in standard and high speed models with many speed and torque versions. This makes our eddy current line perfect for testing a wide range of applications. If you perform engine testing or electric motor testing, we have a system for you.
Dynamatic™
- Founded in 1931 to manufacture the “eddy current clutch”, originally intended for automobiles
- The idea for a self-contained drive with a motor and variable speed clutch is introduced shortly after the eddy current dynamometer
- Derived from the words “Dynamo” and “Automatic”, over the years, Dynamatic has become a highly recognized and respected trade name in both the US and abroad.
Time-honored and well-respected manufacturers of eddy current dynamometers, was acquired by Dyne Systems in 2002.
Features of Eddy Current Dynos include:
- Rated from 5 to 2,500 hp (4 to 1,864 kW)
- Wet and dry gap configurations
- Vertical and/or horizontal test configurations
- Custom options available
