FIELD: electrical engineering.
SUBSTANCE: design of AC starter generators and methods for supplying electric power in a vehicle and engine rotation are disclosed. For example, alternator starter-generator can ensure maintenance of some torque at input side of AC generator at simultaneous change of rotation frequency on output side of alternator. Starter alternator comprises two windings of armature and two excitation windings. At that, the first excitation winding and the first winding of the armature are at least partially enveloped with the second excitation winding, and the first excitation winding and the first winding of the armature are at least partially enveloped with the second armature winding.
EFFECT: technical result is improvement of weight and size characteristics.
