| titleOfInvention | Method for determining angular position of a permanent magnet rotor of a polyphase electric motor |
| abstract | This method consists in supplying at least a first alternating signal, at a determined frequency, to one end of a stator coil and recuperating a measurement signal at a second end of said coil, said measurement signal being provided to electronic processing means, which are arranged to extract data relating to a periodic variation of the effective inductance of the stator coil. This variation is a function of the angular position of the rotor. By alternately carrying out such a measurement on the stator coils, three periodic curves can be extracted (SPCA, SPCB, SPCC) defining a zigzag curve (70) allowing the angular position of the rotor to be determined. |
