Abstract
A connector for an electric motor including a magnetic ring which is the seat of a magnetic field tied to operating parameters of the motor. A magnetic flux conduction member forms a flux concentrator interposed, when a connector is fixed on the motor, between the magnetic ring and a Hall-effect sensor to measure the magnetic flux conducted by the magnetic flux conduction member. The electric motor can be used with geared motors for window-lifting systems, seat actuation systems or sunroof systems in the automobile field.
