| 摘要 |
<p>The invention concerns a device for determining the position ( (t)) ofthe rotor (4) of a rotating electrical machine. The invention is characterizedin that said device comprises a plurality of magnetic field sensors (52u, 52v,52w) stationary relative to the stator (8) and adapted to deliver multiphaseelectric signals (su, sv, sW) representing amagnetic field detected by said sensors, and means for processing (MC) said multiphaseelectric signals by an operator ([M]) capable of providing diphase signals (sin (t),cos (t)) depending on said position. The invention is applicable to rotatingelectrical machines used in the automotive industry.</p> |
