Abstract. A method of identification of electromechanical parameters of the electric drive, based on the method of least squares, is proposed. The method solves the problem of automatic acquisition of experimental data under the conditions of speed and rotation angle limitation. Algorithm realizing the method can be automatically adjusted during its operation to achieve high accuracy of the estimated parameters. An algorithm for servo tracking telescope is presented as an example. The proposed algorithm may be of interest for designers of electromechanical systems with limited motion. Experimental verification of the results on a two-mass bench with variable stiffness coefficient and variable moment of inertia of the second mass was carried out.

Keywords: movement restriction of electric drive, automation of identification, disturbance, precision electric motor, relay control
