Abstract
A polyphase electric motor () of a motor vehicle which includes a rotor () and a stator () surrounding the rotor and including a plurality of stator windings () around stator teeth () defined by notches () in a stator magnetic mass (). According to the invention, the motor includes a device for determining an angular position () and/or the speed of rotation of the rotor, including a plurality of magnetic field sensors () which are stationary relative to the stator. The sensors are arranged in notches () and comprise large casing surfaces extending in planes that are tangential to the stator magnetic mass, such that the sensors detect only a radial component of the magnetic field inside the stator magnetic mass.
