a dynamometer is a machine used to measure torque and rotational speed from which power produced by a motor can be measured the main components of a dynamometer are base provides a stable platform where all components are mounted pedestals provides support and transfers static and rotational forces to the base collection box collects the coolant discharged from the dynamometer after usage rotor shaft the rotating element that is turned by the unit being tested stator housing encases and supports the rotor also assists in cooling
