<p>For controlling the starting of a synchronous electric motor (20), a control unit (10) includes a non-return device (30) which provides a seat (31) for accommodating a rotor shaft (22) of the electric motor (20) and which is adapted to prevent rotation of the rotor shaft (22) in a first direction of rotation by exerting a rebound torque (CR) on the rotor shaft, at least at the time of starting of the electric motor (20), in a second direction of rotation; an amplifier device (40) being provided for amplifying the rebound torque (CR) to a value which is at least greater than a value of a magnetic rotation torque (CEM) of the rotor shaft (22) in the first direction of rotation.</p> |
