The first and second digital processing units (32a, 34a) of the first and second driving sub-systems (32, 34) implement a synchronization algorithm to determine a synchronism between an operation of the first driving sub-system (32) and a corresponding operation of the second driving sub-system (34), said synchronization algorithm including operations that are independent of the use of a common reference clock and are based on a set of predefined signals exchanged between the first and second digital processing units (32a, 34a).

An electric machine rotor (1), in particular for an electric motor for traction of motor vehicles, has two shaft portions (4,5) opposite one another and supported by respective bearings; one of said shaft portions (4) defines an inlet (7) and an outlet (8) for a heat exchange liquid, for cooling an annular wall (10) supporting a plurality of permanent magnets (13), and radially delimits an inner cavity (23) engaged by a core (24); the latter has an axial hole (45) communicating with the inlet (7) to supply a plurality of heat exchange channels (28) through delivery junction channels (44), which are separate from one another and are configured so as to divert the liquid into a radial direction; the liquid is then diverted into an axial direction towards the outlet (8) by return junction channels (38), which are also separate from one another; the delivery junction channels (44) and/or the return junction channels (38) are defined by two surfaces (43,42; 35,36), which axially face one another and define part of the core (24) and of a body distinct from the core (24), respectively.

A motor vehicle (1) includes a body (2), a side door (4) hinged to the body (2) so that it can rotate about an axis towards a side of the motor vehicle (1) between a closed configuration and an open configuration; a motorized opening device (5), which is controllable to move the door from the closed configuration towards the open configuration; command receiving means (7) to receive an opening request command for the door (4) from the outside of the motor vehicle (1); and a control unit (ECU) configured to control the opening device (5) so that the door (4) rotates from the closed configuration towards the open configuration in response to the opening request command.
