Abstract
A motor includes a magnetic ring which is the seat of a magnetic field related to operating parameters of the motor. A connector for the motor includes a magnetic flux conduction member forming a flux concentrator interposed, when the connector is fixed on the motor, between the magnetic ring and a Hall-effect sensor adapted so as to measure the magnetic flux the magnetic flux conduction member. Application to geared motors for window-raising systems, seat actuation systems or sunroof systems, in the automobile sector.
