The work is devoted to development of a controlled unbalanced vibratory drive of directed action with adjustment of the angle of the vibration direction. As a result of researches of the existing constructive decisions of the controlled vibrating drives, the constructive decision which allows to adjust in the adaptive mode optimum from the technological point of view value of an angle of application of cyclic forcing force and to carry out its correction at change of weight of loading of a working body medium that is transported, separated or in which vibration is used to intensify a number of technological processes (e.g. drying in vibration "boiling" layer or etching of grain ...). The design features of the developed vibratory drive allow in automatic mode separately (regardless of the angle of direction and amplitude) to control the frequency of cyclic forcing force in order to ensure and maintain a constant resonant mode and as a result of minimal energy consumption for the vibratory drive. Separate (independent of the angle of direction and frequency) control of the amplitude of the cyclic forcing force of the unbalanced vibrating drive at the resonant (natural) operating frequency of the adaptive vibrating machine allows for automatic adaptive adjustment of the amplitude of body of the vibrating machine (for example, specific power of the vibrating field, specific work of the vibrating field, overload factor).
