Abstract. The problem of centering spatial position of a rotor in mechatronic module used in high-precision processing equipment. The known methods of eliminating the unbalance of the rotating parts of electromechanical and mechatronic devices are analyzed. The main disadvantage of the methods is found to be the principle impossibility of achieving high accuracy in eliminating radial displacement of the rotor. A new approach to the problem of stabilization of a rotating part of the mechatronic module is proposed; the method is based on an active current correction of spatial position of the rotor. Design of the electromechanical part of the device is improved by introducing into it correcting electromagnetic coils and a magnetic system to control over the spatial correction of the rotor. A functional diagram of the proposed method and results of simulations are presented. Methods of synthesis of control loops for variables of the active correction system are discussed. The conclusion is made about technical prospects of the proposed method and on the general direction of the further research. 
Keywords: mechatronic module, automatic adjustment, active stabilization, electromagnet, balancing, unbalance
