Device for determining the angular position of a rotor of a multi-phase rotating electric machine and rotating electric machine comprising such a device

摘要

The device (2) has a tracking loop and a determination unit (221) that determines an estimated value of an angular position of a rotor including two analogue multiplication units (208, 209), rotating magnetic field representing signals, and three sinusoidal signals. A subtraction module (210) subtracts results of multiplications such that a following relationship is satisfied. The relationship comprises specific parameters such as real and estimated angular positions, phase differences of the two of sinusoidal signals with respect to a reference mark related to a stator.
