Design of switched reluctance motor for integrated starter generator

This paper presents a design methodology of Switched Reluctance motor for Integrated Starter Generator in hybrid electric vehicle applications. An ISG is one of the recent research technology in automobile industries. The conventional vehicle needs a Starter motor to start the engine and an alternator to generate the power for battery charging. An ISG operates as the conventional starter motor and alternator in a single machine. With the help of an asymmetric bridge converter, the Switched Reluctance Machine starts up as a motor. The SRM functions as a generator with the switching of an asymmetric bridge converter once the engine starts and accelerates, and it is transformed into a DC supply and stored in the battery. Analytical calculations were used to develop the proposed SRM-based ISG design details, which are optimised for the required torque and speed. In a Finite Element Analysis (MagNet) simulation, the performance of SRM-based ISG is examined.
