STARTER-GENERATOR SYSTEM FOR COMBUSTION ENGINE Russian patent published in 2014 - IPC F02N11/00 

FIELD: electricity.

SUBSTANCE: invention refers to electric engineering, and namely to starter-generator devices for vehicles with combustion engines. In result of this invention comfort of vehicles will be improved and influence of vibrations on durability of the system components will be reduced. The substance of invention consists in the following: starter-generator system for combustion engines contains accumulator of electric energy, for example, capacitance accumulator or accumulator connected electrically to control system including pulse-width converter of voltage, commutator switch and valve electrical machine, which stator is fixed rigidly at combustion engine crankcase and rotor is combustion engine flywheel, and rotor position sensor, which output is connected electrically to commutator switch. According to the invention the system is equipped additionally with the second-order differential section, which input is connected electrically to output of rotor position sensor, and output of the second-order differential section can produce negative feedback signal against the second derivative of rotor turn angle to input of the control system.

EFFECT: reducing irregular rotation of combustion engine crankshaft in result of torque pulsation of combustion engine and vibratory electromagnetic unit.
