Title (EN) COMBUSTION ENGINE STARTER WITH IMPROVED PERFORMANCE
(FR) DEMARREUR DE MOTEUR THERMIQUE A PERFORMANCES AMELIOREES
Abstract: front page image
(EN) The invention mainly relates to a combustion engine starter for a motor vehicle, comprising: - an electric motor (DCM) comprising wound poles and/or permanent magnets and a separate assembly of windings (Wm), - a device for increasing the torque (DAC) equipped with a first coil (W1), termed the transformation coil, mounted in series with said separate assembly of windings (Wm) connected to earth, and with a second coil (W2), termed the accumulation coil, for storing a magnetic energy and returning said magnetic energy to said transformation coil (W1) so that said transformation coil (W1) transforms said magnetic energy into a current circulating in said separate assembly of windings (Wm).
(FR) L'invention porte principalement surun démarreur pour moteur thermique de véhicule automobile comportant: -un moteur électrique (DCM) comprenant des pôles bobinés et/ou à aimants permanents et un ensemble d'enroulements séparés (Wm), -un dispositif d'augmentation du couple (DAC) muni d'une première bobine (W1), dite de transformation, montée en série avec ledit ensemble d'enroulements séparés (Wm) connectés à la masse et d'une deuxième bobine (W2), dite d'accumulation, pour emmagasiner une énergie magnétique et restituer ladite énergie magnétique à ladite bobine de transformation (W1) pour que cette bobine de transformation (W1) transforme cette énergie magnétique en un courant circulant dans ledit ensemble d'enroulements séparés (Wm).
