In Swinburne's Test on D.C.machines, why the efficiency is
more when the machine runs as generator than when it runs as
motor???
Answer Posted / n.dinakar
Swinburne's test is the most commonly used and simplest method of testing of shunt and compound wound DC machines which have constant flux. In this test the efficiency of the machine at any load is pre-determined. We can run the machine as a motor or as a generator.
