Induction-Machine-Based Starter/Generator Systems: Techniques, Developments, and Advances

The starter/generator (SG) system is widely used in various applications, including more-electric/hybridelectric aircraft (MEA/HEA) and hybrid electric vehicles (HEVs). The electric machine operates as a motor to provide the required torque to start the engine. Once the engine starts, the same electric machine transforms to a generator to produce electrical power. With the advantages of a simple and robust structure, low cost and maintenance, and a good overload capability, the cage-type induction machine (IM) is a competitive candidate for SG systems.
