The device comprises a stator (2) including a winding (5) disposed around a stack (3) of laminations and with which is associated a permanent magnet rotor (4). Controlled conductor devices (12) are connected to the stator winding (5) and to an AC source (13, 14). One or more position sensors (10) determine the application to the control inputs of the said controlled conductor devices (12) of electrical control signals having to states which vary as a function of the angular position of the rotor (4). The arrangement is such that the current is caused to flow in the stator winding (5) in a direction which depends only on the polarity of the voltage of the source and the instantaneous position of the rotor (4). <IMAGE> |
