摘要： The invention concerns a connector for an electric motor, said motor comprising a magnetic ring (21) which is the source of a magnetic field relative to the engine operational parameters, which includes a magnetic current conducting member (35) forming an interposed magnetic current concentrator, when the connector is fixed on the motor (2), between the magnetic ring (21) and a Hall-effect sensor (33) adapted to measure the magnetic current conducted by the magnetic current conducting member (35). The invention is applicable to gear motors for window lift systems, seat or sliding roof actuators, in motor cars.

摘要： The invention relates to a device (10) which is used to determine the movement of a shaft, comprising a crankshaft (12) which is rotated around an axis (13) and which can move along the length of said axis (13), a multi-pole magnet (14) and a sensor (16), said sensor (16) or magnet (14) being rotated by the crankshaft (12). The magnet presents the sensor (16) with north and south poles (15) which alternate according to the relative angular position along the axis (13) of the sensor (16) and the magnet (14), the poles (15) being made from a magnetisable material. The movement of the shaft along the axis thereof can be detected according to the detected alternating poles. The invention also relates to a geared motor, a window regulator and a magnet.
