摘要：

Capacitor start, capacitor-run single-phase induction motors are analyzed by means of the rotating field theory using the method of symmetrical components. The novel approach of this paper is based on the current ratio -γ, relating the backward and forward rotating components of the main and auxiliary-phase winding currents. Since the losses of such a machine are greatly dependent upon the elliptic shape of the rotating field such an analysis in terms of γ will be of value for any efficiency optimization. The dependency of the efficiency on the run capacitor capacitance is investigated. Since the parameters of the equivalent circuit are slip, temperature and saturation dependent, a computer program was developed which determines in an iterative manner the performance of such machines. A large number of tests were performed for a 4 pole, 2 Hp, 115/230 V motor. The experimental data corroborate the calculated characteristics which show that the maximum efficiency is reached for a nonzero but small value of γ. © 1990 IEEE
