How Dynamometers Work

All dynamometers perform the same requisite function, measuring the torque, rotational speed and power output of a combustion engine, electric motor or other power source. While the outcome is the same, many technologies are used to perform the desired result.

Two Main Types

Most dynamometers can be settled within two safe bet categories. machine dynamometers are designed for coupling directly to the driveshaft of an machine under test, and chassis dynamometers quantum the power output of a drive train by using rollers turned by the tires of a vehicle under test. In increasing to the two former types, Taylor offers a line of portable dynamometers that attach directly to the flywheel of an engine. This allows literal, measurement of machine output without extraction of an machine from its drive train.

A collection of Designs

The work of handling and measuring input power is performed by instruments with a collection of dissimilar designs:

o Eddy current dynamometers gift a measurable resistant force to engines under test by harnessing the magnetic flux in the middle of fixed and rotating electromagnets spun by the machine under test.

o A variant of the eddy current design, powder dynamometers create flux straight through the application of a fine magnetic powder in the middle of the rotor and coil

o electric motor/generator types are a discrepancy on the adjustable speed drive, using solid state components rather than the physical association in the middle of electromagnets to create measurable power transfer

o Fan, hydraulic and water brakes use air, water or hydraulic fluid to deliver physical resistance to the power applied by an machine or motor under test. The estimate of resulting force absorbed by the fluid is measured to supply an indication of the power applied to the system

Eddy Current Dynamometer History

The story of the eddy current dynamometer is a tale of two Danish boys from Wisconsin, growing up in a time when innovations required an inquiring mind and a machine shop rather than a supercomputer and a doctoral degree. Martin Phillip Winther arrived at Ellis Island, New York in 1892 from his native Denmark. The family ultimately settled in Kenosha Wisconsin, where Martin and his American-born brother Anthony began their working lives as laborers at the Jeffry Company, makers of the Rambler automobile. At Jeffry, the brothers were complex in the engineering of a four-wheel-drive truck, which led them to break away and found the Winther Motor and Truck company in 1917. While Winther Motor and Truck made several types of motor vehicles (including light trucks, fire engines and a sporty automobile) the firm's chief goods was innovation. Beginning nearby 1920, Martin and Anthony Winther were granted patents for approximately 300 mechanical devices. These included the first flourishing air conditioning principles for Pullman hasten cars, a four-wheel-drive post hole digger for At&T, the first induction coupling, a magnetic clutch, a cycle-car, variable-speed transmission gears, as well as a giant press drive, brakes and couplings for the oil field industry.

Although prolific, only one of the Winther brothers' inventions proved to have continuing impact. They are chiefly known for the invention of the eddy current dynamometer, a type of high speed, high power dynamometer capable of far surpassing the products then available in terms of power handling capability. The eddy current dyno was able to turn fast sufficient to test the turbine engines used in aircraft, wind tunnels and high speed automobiles of the day. The eddy current dynamometer was the chief goods of the Dynamatic Corporation, founded by the Winthers in 1932. The firm was flourishing for many years both before and after the brothers sold their interest to Eaton Corporation in 1946. Variations on the eddy current originate still serve as the basis for dynamometers today. The designs continued use is a testament to the ingenuity of two men who never rose above the eighth grade in formal education, yet parlayed their requisite on-the-job understanding into a continuing inheritance of technical achievement.
