Modelling and simulation of SRM based automatic transmission system for hybrid vehicles in Ansys Maxwell

Abstract

The automobile industry is a rapidly developing sector. Technological innovations are advancing in this field. As a measure of controlling environmental pollution, several bills have been passed by different governments such as banning production of diesel vehicles which shows a chance for electric vehicle sector to become the future of automobile industry. So, new and improved technologies are required in this sector for improving the performance of different kind of electric vehicles. Gear transmission system is used in vehicles in order to control its speed and torque. Many electrical motors can be used for hybrid electric vehicles which can be in-cooperated with gear transmission system. Under recent studies, it has found that Switched Reluctance Motor (SRM) a special electric machine is more useful and cost effective for using them as prime mover which can itself used as gear transmission system, but it needs a control circuit for proper working. For transmission purpose, a multi-stack SRM has to be developed. For an automatic transmission system, there is a requirement of an improved structure for the SRM which can provide both linear as well as rotary motion. The modelling and simulation of such a kind of machine will be done in Ansys Maxwell 3D, in this thesis work.
