The present dissertation is focused on the methodology of modelling of the machine tool drive. The initial chapters contain a review of the current state of knowledge in the field of drive modelling with a focus on the electromagnetic part, thermal field and drive control. The acquired overview and orientation in the subject matter has enabled the development of a systematic analysis on the topic of modelling the machine tool axis drive. The follow-up work was aimed at obtaining the appropriate quality of the output parameters, according to the subsequent use of the results. The reason for this approach is to ensure only a minimum of input parameters. At the same time, the individual parameters must be readily available or easily measurable. The actual methodology of the drive modelling method was also based on the described strategy. The basic building blocks were chosen to be the warming of the machine, the energy balance, the setting of the control structure and, last but not least, the positioning accuracy. The applied methodology was also verified at the end of the thesis under different operating conditions, which were adapted to multiple drive variations.
