1. A drive system comprising:
a first electrical motor comprising a first rotor provided with a first rotor shaft developing along a rotation axis;
a second electrical motor flanking the first electrical motor and comprising a second rotor provided with a second rotor shaft coaxial and distal to the first rotor shaft; and
an interface configured to interface the first electrical motor and the second electrical motor;
wherein the interface comprises:
a first element coupled to the first rotor and developing circumferentially around the rotation axis towards the second rotor;
a second element coupled to the second rotor and developing circumferentially around the rotation axis towards the first rotor so as to overlap the first element in an overlapping area; and
at least one interfacing bearing radially interposed between the first element and the second element in said overlapping area.
