Experimental tests have been carried out on a small induction motor connected for six phases and for nine phases. These include torque measurements over the entire speed range and load tests with balanced source and with one phase open. Some of the machine impedances, including sequence impedances, were measured and these generally agree with predicted values. The motor was subjected to source voltages having harmonics and the measured currents show good agreement with theoretical values based on the analysis in a companion paper.
