Abstract :
Two test methods for the determination of stray load losses in d-c machines are described. Application of the loading-back principle permits measurements to a high degree of accuracy. A technique is developed for stabilizing no-load losses so that consistency of results is improved. Results of tests of several machines are presented, together with an analysis of the relation of loss to operating conditions of the machine.
