The invention relates to an electromagnetic coupler for a motor vehicle. The inventive coupler consists of: a first electric machine having an axis A and comprising a first stator (50) bearing a first coil (52), an input rotor (20) and a first part (23; 157) of an output rotor (30); and a second electric machine comprising a second stator (40) bearing a second coil (100) and a second part (44; 177) of the output rotor (30). The input rotor (20) comprises an inner drum (77) which is spaced apart from the first part (23; 157) of the output rotor (30) and from the first yoke (60), while the second yoke (43) is spaced apart from the second part (44; 177) of the output rotor (30) by a second air gap (98; 106). According to the invention, the first coil (52) is wound onto the yoke (60) of the first stator (50) around axis A. Coupleur électromagnétique pour véhicule automobile, comportant - une première machine électrique d'axe A comportant un premier stator (50) portant une première bobine (52), un rotor d'entrée (20), et une première partie (23 ;157) d'un rotor de sortie (30), - une deuxième machine électrique comportant un deuxième stator (40) portant une deuxième bobine (100), et une deuxième partie (44;177) du rotor de sorbe (30), le rotor d'entrée (20) comportant un tambour intérieur (72) écarté de la première partie (23;157) du rotor de sortie (30) et de la première culasse (60), la deuxième culasse (43) étant écartée de la deuxième partie (44 ; 177) du rotor de sortie (30) par un deuxième entrefer (98 ;106). Selon l'invention, la première bobine (52) est enroulée sur la culasse (60) du premier stator (50) autour de l'axe A.
