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.

基于感应机的启动器/发电机系统：技术，发展和进步

起动机/发电机（SG）系统广泛用于各种应用中，包括更多电动/混合动力飞机（MEA / HEA）和混合动力汽车（HEV）。电机作为电动机运行，以提供启动发动机所需的扭矩。发动机启动后，同一台电机将转换为发电机以产生电能。笼式感应电机（IM）具有结构简单，坚固，成本低，维护成本低以及过载能力强等优点，是SG系统的有力竞争者。
