N2 - Temperature rising test is one of the most important electrical machine tests which used to determine the name plate values of an electrical machine and is a key element in confirming that the machine is designed for use within its designed operating capability. As defined in standards, an induction motor is loaded gradually and winding temperature is measured time steps in temperature rising tests. Generally, dynamo brakes and resistive load banks which needs additional effort to adjust settings during the tests. During the test, winding resistance change depending on the rising temperature resulting in a change in motor torque and extra effort is needed to keep the torque unchanged. In this study, a current controlled eddy current brake is used for loading an induction motor instead of traditional dynamo brakes to perform the temperature rising test with a constant load torque. A closed loop control system is designed with conventional PI controller to obtain constant braking torque.
