Regenerative Dynamometers Using D. C. Machines 800410
Developed in the general industrial field the d.c. machine with S.C.R. control is being increasingly applied to engine testing. The versitility of the system allows the use of a foot-mounted machine with shaft torque determination by on line calculation methods and variable effective inertia. Coupled with this, its ability to regenerate energy directly into the factory supply is used to recover the engine out-put in a directly usable form.
