An investigation into the suitability of unbalanced motor operation, the Eh-star-circuit for stray load loss measurement

The concept of obtaining stray load loss results from a test on an unbalanced motor is examined and its advantages shown. Computed results are presented which confirm the potential of the method. Experimental results also support the idea that this type of test may have merit particularly for purposes of checking on quality of production where expensive test facilities are undesirable.
