A Basic Analysis of the Commutatorless Primitive Machine of Kron

This paper, a result of inspiration and motivation given to the author by the equivalent circuits of the induction machine in all its forms. It starts from the differential equations of the primitive machine and then obtains the steady-state solutions of these equations for the various modes of operation. The equivalent circuits are drawn so as to satisfy the steadystate solutions. The physical model of the primitive machine used here is one descrabed by White and Woodsonl1. The Physical parameters of the actual machine are used throughout the paper. The three main cases are considered: 1. The machine symmetrical only on stator side of the air gap. 2. The machine symmetrical only on the rotor side of the air gap. 3. The machine asymmetrical on both sides of the air gap. The equivalent circuit for the last case differs significantly from that of Kron´s. The emphasis is placed on logical continuity in the analysis.
