This paper analyzes the performance characteristics of a three-phase induction motor operating according to the steinmetz connection in which the capacitor is connected across the leading phase winding. The two capacitive reactances of capacitor are determined at the starting and rated speed using the condition of minimum voltage unbalance factor of steinmetz connection. The applicability of these capacitors is investigated by comparing the computed results in the whole slip range with the balanced three-phase operation. It is found that the capacitive reactance at the starting is more suitable for single phase operation.
