Abstract
A device for determining the position of the rotor of a rotating electrical machine. The invention is characterized in that the device comprises a plurality of magnetic field sensors stationary relative to the stator and adapted to deliver multiphase electric signals representing a magnetic field detected by the sensors, and means for processing the multiphase electric signals by an operator capable of providing diphase signals depending on the position of the rotor. The invention is applicable to rotating electrical machines used in the automotive industry.
