The Prony brake is a simple type of dynamometer used to measure the amount of torque produced by a motor or engine in order to determine its brake horsepower rating. The device was invented in 1821 by a French engineer named Gaspard de Prony, and continues to be widely used by tractor and heavy equipment manufacturers.
A modern Prony brake usually consists of some type of brake drum along with a pulley that is connected to an engineâs output shaft on one side, and a brake lever on the opposite side. A device used to measure the amount of force being applied to the brake arm is also attached to the Prony brake as well. An additional device is utilized to measure the number of revolutions per minute (RPM) that the engineâs output shaft is turning during the test.
