Abstract[English]
An electrical machine is disclosed, the electrical machine comprising a plurality of rotors (12) and a common stator core (14). The rotors (12) have axes of rotation which are spaced apart. The common stator core (14) comprises a plurality of chambers (16), each chamber accommodating one of the plurality of rotors. Each of the chambers (16) comprises a plurality of stator slots (18) which accommodate stator windings. Each of the rotors is arranged to interact with the stator windings of the chamber within which the rotor is accommodated. A torque transmission mechanism (24, 26) may be provided to transmit torque between each of the rotors (12) and a common shaft (44).[French]
L'invention concerne une machine électrique, la machine électrique comprenant une pluralité de rotors (12) et un noyau de stator commun (14). Les rotors (12) ont des axes de rotation qui sont espacés. Le noyau de stator commun (14) comprend une pluralité de chambres (16), chaque chambre contenant l'un de la pluralité de rotors. Chacune des chambres (16) comprend une pluralité de fentes de stator (18) qui reçoivent des enroulements de stator. Chacun des rotors est agencé pour interagir avec les enroulements de stator de la chambre à l'intérieur de laquelle le rotor est logé. Un mécanisme de transmission de couple (24, 26) peut être prévu pour transmettre un couple entre chacun des rotors (12) et un arbre commun (44).
