Abstract (en)

The driver (19) includes, in series with the motor (11), a two-way solid-state switch (23), the trigger voltage of which is supplied via a resistor (27) connected between the control terminal (26) of the two-way switch (23) and the motor (11). When the safety lock is operated electrically, the supply voltage is supplied to one of the inputs (5, 6) of the driver (19) to trigger and so close the two-way switch (23) and supply the motor (11) normally. In the absence of the electric open/close command, the two-way switch (23) is open, and the motor (11) finds an open circuit at its terminals, so that, when the safety lock knob is operated manually, the motor (11) rotates without generating any counter-electromotive force and, hence, with substantially no resistance. <IMAGE>
