The Swinburne's test on DC shunt motor is applicable to find the losses in the machine with no-load power. The losses in the motors are armature copper losses,To conduct Swinburne's test on DC shunt machine and to pre determine its efficiency. Apparatus: S.No Name of the Apparatus Type. Range. No. of required. Speed control of DC shunt motor and Swinburne's test on DC shunt motor in this position through out the experiment as its variation changes the field Since constant losses are known, efficiency of Swinburne's test can be pre- determined at any load. Procedure of Retardation Test on D.C Machines. Rheostats – to vary field current of motor and generator respectively. PROCEDURE : 1. Connect the two DC machines, coupled mechanically as per the circuit TITLE OF EXPERIMENT. PAGE NO. 1. 0.C.C. of Separately excited DC Generator. 2. Swinburne's Test on DC Shunt Motor. 3.
