Abstract
This final project deals with the modelling of a vector-controlled bearingless synchronous reluctance motor (BSyRM) drive. The goal of this project is to develop the dynamic model of a BSyRM. A brief introduction going through the advantagesand disadvantages of conventional machines shows the importance of BSyRMs development. An explanation about the general aspects and operating principles of BSyRMs is presented together with the general dynamic model equations of the permanent-magnets synchronous machine. Several assumptions are considered toadapt the permanent-magnets machine model to the BSyRM model desired. The description of the controllers employed in the vector control implementation is also included. The study is made through a literature review and by simulation using the Matlab/Simulink software. The implementation of the BSyRM dynamic model and vector control and the simulation results are presented. Simulations show that the model developed is well suited for the BSyRM.
