This paper analyzes the stator winding currents of a three phase induction motor which is connected to the single phase supply. Two stator configurations, Steinmetz connection and modified Steinmetz connection, are respectively employed. In each case, the phase converter reactance at starting is determined using the condition of minimum voltage unbalance factor. By using this reactance, the stator winding currents of each connection are computed and compared with the results of three phase balanced operation.
