The article analytically establishes the power of drives to ensure stable vibrations of vibration machines of various types of disturbances with a simple and complex movement of the working element. The parameter of the phase shift between displacement and the perturbation force is used as the determining parameter characterizing the power costs. This approach ensures the power of the drive at maximum load, laying, a priori, a certain margin for energy costs. Specific analytical dependencies are proposed to establish the power of single-mass vibration machine drives with inertial, crank-conrod and inertial drives. The proposed analytical dependencies are extended to multimass 

systems.
