The dynamometer has always been part of the performance measurement because the presence of horsepower is usually accompanied by four hooves and a tail. This versatile tool is used around the world, just like a company from

Based on past innovations, new breakthroughs have been made in data collection and system control technologies.
- In 1828 Gaspard de Prony invented de Prony Brake, one of the earliest dynamometers
- In 1838, historian called the father of computers, Charles Babbage, introduced a dynamometer to measure the traction of British railway locomotives.
- In 1877, William Froude of the United Kingdom entered the first hydraulic dynamometer, and in 1881 produced the first commercial models.
- In 1921, Professor EV Collins of Iowa State University developed a horse-type dynamometer to measure the era of horses pulling heavy metal tools.
- In 1930, John Taylor used the design pioneered by Rudolf Diesel to form a Taylor dynamometer and machinery company to produce engine dynamometers.
- Martin and Anthony Winther launched the first eddy current dynamometer in 1931

How the dynamometer works
All dynamometers perform the same basic functions to measure torque, speed and power output from internal combustion engines, electric motors or other power sources. Although the output is the same, many techniques are used to achieve the desired result.
Two main types
Most dynamometers can be placed in two different categories. The engine dynamometer is designed to be directly connected to the drive shaft of the engine under test, and the chassis dynamometer measures the power output of the drive train by using a roller that rotates the tire of the vehicle under test. In addition to the two traditional types, Taylor offers a range of portable dynamometers that can be directly connected to the flywheel of the engine. This allows accurate measurement of engine output without removing the engine from its driveline.
The process of processing and measuring input power is performed by instruments with a variety of different designs:
o The eddy current dynamometer provides measurable resistance to the engine under test by utilizing the magnetic flux between the fixed and rotating electromagnets that the engine is being tested to rotate.
o A variant of the eddy current design in which a powder dynamometer produces magnetic flux by applying fine magnetic powder between the rotor and the coil
o Motor/generator type is a variant of an adjustable speed drive that uses a physical relationship between solid components rather than electromagnets to produce measurable power transfer
o Fans, hydraulic and water brakes use air, water or hydraulic fluid to provide physical resistance to the power applied by the engine or the motor under test. Measuring the amount of resultant force absorbed by the fluid to provide an indication of the power applied to the system

Eddy current dynamometer history
The story of the eddy dynamometer tells the story of two Danish boys from Wisconsin who grew up in the era of innovation that required spiritual and mechanical processing rather than supercomputers and doctorates. Martin Phillip Winther arrived in Ellis Island, New York, from his native Denmark in 1892. The family settled in Kenosha, Wisconsin, where Martin and his brother Anthony, who was born in the United States, began their work and life as an employer of the car manufacturer Jeffrey. At Jeffrey, the brothers participated in the design of the four-wheel-drive truck, which led them to leave and found the Winther Motor and Truck Company in 1917. Winther Motor and Truck manufactures several types of cars [including luminaires], trucks and sports vehicles. The company's main product is innovation. Since about 1920, Martin and Anthony Winther have patented nearly 300 mechanical devices. These include the first successful Pullman railcar air conditioning system, a four-wheel drive rear boring machine for AT&T, the first inductive coupler, a magnetic clutch, a bicycle, variable speed drive gear, and the oilfield industry. Giant presses, brakes and couplings.

Although prolific, only one Winther brother ' invention has proven to have lasting effects. They are mainly used in the invention of eddy current dynamometers, which are high-speed, high-power dynamometers that can far exceed the products available at the time in terms of power handling capabilities. The eddy current motor is able to rotate quickly to test the turbine engines used in airplanes, wind tunnels and high-speed cars that day. The eddy current dynamometer is the main product of Dynamical, founded by Winthers in 1932. The company succeeded years before and after the brothers sold their interest to Eaton in 1946. Changes in eddy current design are still valid. As the basis of today's dynamometer. The continued use of these designs demonstrates the ingenuity of two men who have never exceeded eighth grade in formal education, but they have fully demonstrated their insights in the long-term nationality of technical achievement.
