Swinburne Test on DC Shunt Motor. 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, iron losses in the core, friction losses, and winding losses.
Swinburne’s test (named after James Swinburne) is an indirect method of testing a DC shunt or DC compound motor. During this test, the motor is not loaded. Therefore, this method of testing is also known as No-load Test.
Swinburne’s Test is an indirect method of testing of DC machines. In this method, the losses are measured separately and the efficiency at any desired load is predetermined. Machines are tested for finding out losses, efficiency and temperature rise. For small machines direct loading test is performed.
The Swinburne test is a no-load test used to predict the efficiency and performance of a machine. However, it does not provide accurate results for temperature rise and commutator segments. An alternative test involves two mechanically coupled machines operating as a shunt motor and a generator.
