Motor core losses are usually evaluated as the total loss minus known losses, including copper and mechanical losses. However, it is difficult to identify the main cause of core losses based on this evaluation method. In our previous study, we proposed a method for directly evaluating core loss distribution based on heat measurements using a thermographic camera. In this paper, we examine the reliability of thermal measurements using a device that can simultaneously measure core loss both by the general magnetic method and by the thermal measurement method. In the comparison method, the magnetic loss and thermal measurements are conducted simultaneously using an open magnetic path single sheet tester that permits simultaneous direct imaging of a sample with a thermographic camera, and the core loss values are compared and examined. We demonstrate a good agreement between the thermal and magnetic measurement below 10% difference for flux densities higher than 1T.
