Eddy Current Dynamometers (Dynos) Providing Precise Control and Low Maintenance

Eddy Current dynos are simple, moderately priced, torque measuring devices for a large spectrum of test purposes. The speed and torque characteristics are ideal for testing a wide range of applications including electric motors and many types of engines.

Midwest®
  • Originally established in 1922 by Midwest Dynamometer & Engineering Company
  • One of the original innovators that used eddy current technology to manufacture dynamometer technology
and
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, were 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
