Dispositif d'entraînement pour une porte de véhicule motorisée pourvu d'un détecteur de mouvement

摘要

A drive assembly (42) for a vehicle door (14), comprising: a motor (60) having a driving member (62); a housing having a shaft (68) rotatably received therein; an input member (64) being rotatably received upon the shaft, the input member being operatively associated with the driving member, wherein rotation of the driving member causes rotation of the input member; an armature (73) mounted on the input member; a rotor (72) fixedly secured to the shaft, the rotor being cylindrical in shape and has a plurality of teeth (75) positioned along the periphery of the rotor, the teeth being positioned in an equidistant manner; a coil (70) mounted to the housing, the coil providing magnetic flux lines through the rotor to attract the armature when the coil is energized; and an inductance sensor assembly (80) mounted to the housing in a facing spaced relationship with respect to the plurality of teeth of the rotor, wherein rotational speed and direction of the rotor is detected by the inductance sensor assembly.
