Abstract
This paper compares direct, by calorimeter, and indirect, by harmonic injection, methods for measurement of inverter induced, harmonic power loss across a range of induction motors from 1.1 to 30 kW. Techniques to obtain the necessary experimental precision are described. Comparisons between segregated losses for the machines operating on sinusoidal supplies show a link between iron loss and high frequency PWM induced loss. Iron loss is not a constant proportion of total loss for all machines so that neither is harmonic loss independent of machine design
