An electric drive comprises a multiphase source (1) of sinusoidal voltage with a pick-up (3) of the angular position of the rotor of the synchronous motor (6). The stator windings (19) are connected, through an adjustable current source (17), to a unit (11) of phase-sensible rectifiers. Steering inputs (25) of the unit (11) are connected, through a unit (20) of multipliers, to a current pre-setting device (23). The electric drive comprises as well a reference signals former (7) connected with its output to the inputs (10) of the unit (11) and with its input to the output (8) of he pick-up (3) of the angular position of the rotor.
