Midwest Eddy Current Dynamometers

Durable, Dependable, Proven Design

Midwest Dynamometer & Engineering Company was founded in the early 1920's and served the growing internal combustion engine industry. It gained a reputation for providing robust and reliable eddy current dynamometers, which it still enjoys today. Models range from 5 to 4000 horsepower, and are available with both wet and dry gap construction.

Why Eddy Current?

The development of the eddy-current dyno has made available to the industry simple, low cost, compact torque measuring equipment for a large spectrum of test purposes. The speed-torque characteristics of these dynamometers are ideal for engine testing and their versatility also allows effective use of these units in testing transmissions, turbines, electric motors, gears, pumps and many other machines.

Model 932 ranges from 775 to 4000 HP and from 11,971 to 31,512 ft. lb. of torque

Model Specifications

Speed, horsepower, torque and inertia specifications will determine which model is correct for your application. This data for all Midwest and Dynamatic models are listed in the dynamometer specifications table, organized by horsepower. From this listing, you can also view all speed-torque curves.

Backed by Factory Warranty

All new Midwest™ eddy current dynamometer models are manufactured (and tested when possible) in our production plant, and carry a two year factory warranty.

Horizontal or Vertical Shaft Configuration

Virtually any Dry Gap (DG) model Midwest or Dynamatic dynamometer can be configured for vertical shaft applications (see example in the photo at right). And, for the ultimate in small engine (from fractional to 75 HP) dynamometers, check out our multiple-position “tilt stands” which utilize shaft orientations that imitate the angles in which an engine might operate under real-life conditions.
