In this paper, the pulling-into performance of synchronous motors taking account of influence of field circuit is analyzed using Lyapunov's direct method. The method enables one to directly judge the stability without solving the nonlinear differential equations representing motor involved. The influence of all machine constants on synchronization of synchronous motors is assessed. The analyzed results show that field constants have effectively large influence on the pulling-into performance.
