This paper shows the results of the study to obtain the transfer function of a DC motor, based on the response between the armature voltage and the angular speed, as input and output signals. In the second part, it is shown how two of its parameters, the armature current and the angular speed, change with the variations of the armature voltage; these data have been taken by measurements made in the motor. The task is made on three different motors, two of permanent magnet and one of winding stator. In the third part, it is made an analytical model of the motor based on its electromechanical model representation and the function of transfer is defined as well. In the fourth part, measurements are made to determine the motor parameters by experimental methodology and find the transfer function based on them. In the fifth part, MATLAB «Ident» toolbox is used to find the transfer function of the motor and compare it with the obtained through experimental methods. In the sixth part, there are given the conclusions on the results obtained.
