During the conventional starter and alternator (generator) of an braking the ISG can convert the vehicle’s kinetic energy into automobile in a single electric device. It allows greater electrical electrical energy, and then feed this power back into the generation capacity and the fuel economy and emissions benefits electrical system. of hybrid electric automotive propulsion. The ISG requires As it fully supports the stop-and-start operation, electric contrary specifications, i.e. a high starting torque and a field- dr
