ELECTRIC MOTOR

摘要

The invention relates to a motor (1) provided with a secondary driving system including: a casing (2); a dented wheel (5) permanently rotating during the normal operation of the motor together with the rotor inside the casing; an endless screw (6) that can be brought into a clutch engagement position in which the screw meshes with the dented wheel and in which the rotation of the screw drives the dented wheel in a non-reversible manner and that can be removed from said position in order to allow the normal operation of the motor; a driving member (8) for manually rotating the endless screw, the driving member rotating about the same rotation axis as the endless screw and rotating the latter by direct engagement.
