A. C. Absorption Dynamometers

This is a single phase or three phase alternator, of special design, depending upon its capacity and application.The power developed by the prime mover is absorbed in a load bank. 

Load control is obtained partly by armature control(coarse), and partly by field control, (fine).

APPLICATION
AC Absorption dynamometers are ideally suited for testing petrol engines for mopeds and electrical F.H.P. motors. Their main advantage lies in the fact that they are self aircooled and hence water cooling or additional air cooling is not required. This advantage is particularly significant in case of moped engines and F.H.P.
