Determination of the efficiency of a dc motor by loss summation method(Swinburne's test)
  1. To know what are the various power losses which take place in a d.c machine.
  2. To understand the factors on which various losses depend upon.
  3. To know how to calculate efficiency.
  4. To know how to estimate and predict efficiency of a d.c shunt motor by doing simple tests.
