| 摘要 |
<p>The invention relates to an electric machine (1) comprising a rotor (2) including on the surface thereof at least two separate areas of magnetic permeability (7), and a stator (5) including at least two power coils (4A-4A', 4B-4B', 4C-4C) capable of generating a main magnetic field, as well as at least one sensor (6A, 6B, 6C, 46A, 56A) generating a signal representing the angular position of the rotor relative to the stator, characterised in that the sensor is secured to the inner surface of the stator and comprises: a substrate (10) made of a ferromagnetic material with an elongate shape, wherein the longest axis of the substrate is substantially parallel to the axis of rotation of the rotor (2); and an electric circuit forming at least one pick-up coil (15A, 15B, 15C) wound around the substrate.</p> |
