Parameter identification for standardization of motor loss distribution measurement using thermographic camera

Accurate measurement of the distribution of losses in the motor core is crucial to increase motor efficiency. However, detailed analyses of factors contributing to increased iron losses have not been conducted. Therefore, existing approaches cannot be used as reproducible measurement methods. This study proposes a procedure to measure the loss distribution and identify parameters for improving the reproducibility of measurements. A designer can visualize the iron-loss distribution to compare the actual and designed iron losses and increase the efficiency of the motor. Results indicated that the number of repetitions was a major parameter affecting the measurement accuracy.
