When synchronization occurs in a system where several nonlinear self-excited oscillators with different natural frequencies are coupled, the frequencies of all the oscillators are entrained due to the interaction. While to date many researchers have examined characteristics of this phenomenon, its mechanism has not been completely clarified. In order to provide new insights into the mechanism, this paper considers a system consisting of two DC motors and analyzes the energy condition which needs to be satisfied in a synchronized state. It is seen that the derived condition is able to predict the range of synchronized frequency and the applied voltage where synchronization occurs.
