The present paper shows the condition for which three motors working on the same plate can enter into synchronization with the phase difference equal to 0, π/5, 2π/5, 4π/5, π8π/5, or 2π depending on the physical characteristics of the motors and the plate. The motors are considered as non-ideal oscillators and act as external excitation on a specific area of the plate. The analysis of the vibration of the plate indicates through numerical simulation that one can obtain a reduction of vibration when the motors are different and rotates in opposite directions.
