Dynamatic™ and Midwest® Dynamometers

Eddy Current Dynos

Midwest and Dynamatic, time-honored and well-respected manufacturers of eddy current dynamometers, were acquired by Dyne Systems in 2002. With today’s materials, technology, engineering and manufacturing techniques, significant improvements in eddy current dynamometer design and manufacturing have been achieved. Midwest and Dynamatic dynamometers offer a wide range of choices in torque, speed and horsepower, and are a natural fit with Dyne Systems controls, test automation and data acquisition products. Having all components produced under one roof, with collaboration between departments, is an obvious advantage when integrating a system.

  • Speed-torque characteristics ideal for engine testing and a wide range of other applications
  • Midwest and Dynamatic models rated from 5 to 2,500 Hp provide a wide range of speed and torque ratings and combinations
  • Dry Gap and Wet Gap models cover every application
  • Vertical and/or horizontal configuration available on virtually any dry gap model, up to 2,000 Hp
  • Two-position vertical/horizontal tilt stand rated for engines or motors from 3 to 75 Hp, and multi-position tilt stands rated for 1 to 40 Hp
  • Custom horsepower and speed ratings available upon request
  • Used eddy current dynamometers in stock, ready to be remanufactured
  • Remanufacturing and repair of your current Midwest or Dynamatic dynamometer to OEM specifications
  • New manufacturing and remanufacturing of used units performed by the same team of dynamometer experts at the Dyne Systems plant in Jackson, Wisconsin
  • Standard one year factory warranty for both new and remanufactured eddy current dynamometers
