The transient electric dynamometer construction consists of a cast housing and two end-shields with integrated mounting feet. Water cooling is the standard design. This dynamometer series is used for electrical vehicle motor testing and applications related to aviation and aerospace.
It is suitable for development and function tests of engines, transmissions, powertrains, and e-motors. 
 it adjusts the electromagnetic torque to change the load and speed of the engine, absorbs the mechanical work output from the tested engine, and converts it into electric energy.
