Nowadays computer aided design is an indispensable resource in engineers’ work. Over the years more and more accurate models have been worked out, which lie closer to devices’ or systems’ real behavior. As a result money and time can be saved.

During the last decades many studies have dealt with switched reluctance machines and drive technology. Semiconductor devices appeared in the mid 1900’s and widespread in the next decade was one of the main reasons. This had a positive impact on performance, so this was again to the fore. Based on the results worth dealing with this area and investing in the developemt.

My thesis is about simulating and testing the properties of a switched reluctance motor. In the first part I will present its operation in detail and explain the possible constructions. I emphasize the salient features and list some applications with the manufacturers.

Even though all the considerations cannot be exhaustively listed, I expaund some used converter topologies with advantages and disadvantages, then I discuss the control strategies. The differences between the SRM and the conventional DC and AC machines will be highlighted in the field of motion control.

Through modeling methods of the drive system the Matlab/Simulink environment and the model used will be presented. Furthermore I evaluate the system and the simulated waveforms.
