When self-synchronization occurs in a system where multiple nonlinear self-excited oscillators with different natural frequencies are coupled, all oscillators vibrate at one specific frequency due to their interaction. While many researchers have examined characteristics of this phenomenon, the mechanism has not been completely clarified. In order to obtain new comprehensions into the occurrence mechanism, this paper considers a system consisting of two DC motors, and analyzes the energy condition necessary for synchronization, for the two cases of co-rotation and counter-rotation. It is seen that the derived condition is able to predict the range of synchronized frequency and the applied voltage where synchronization occurs.
