Abstract
This paper offers a new method to analyze the performance of three-phase synchronous machines operating with an unsymmetrical stator winding caused by cut-out and bypassed coils. The resulting unsymmetrical current distribution in the stator winding tends to produce overheating of parts of the winding at full load and torque pulsations. Thus, the main objective of this study is to determine the maximal load, under which the unsymmetrical machine may operate without exceeding the permissible temperature limit. Based on the multiloop method, a mathematical model of a synchronous machine with missing coils in the stator winding is developed. In order to determine the current distribution, the machines' system of differential equations is solved by using a numerical integration method (Runge-Kutta method). In this case, both the circulating current within parallel branches and the line currents of the different phases as a result of coil or coil group cut-outs are analyzed.
