    Abstract: An integrated position resolver for hybrid synchronous electric motors. The present invention represents new improved integrated position resolver for hybrid synchronous electric motors which uses the magnetic flux of the motor also for operation of the resolver. The solution is achieved with an additional measuring coil in the motor and with a small change in control electronics. The measuring coil (1) measures changes of the magnetic flux through the parmanent magnet (4) and the control electronics provides the phase shift of the PWM pulses in successive phases.

    Abstract: The invention concerns a method which consists in supplying a first alternating signal to one end of at least a stator winding, at a specific frequency, and in recovering a measurement signal at the other end of said winding, said measurement signal being supplied to electronic processing means adapted to extract an information concerning a periodic variation of the stator winding effective inductance. Said variation is a function of the rotor angular position. By alternatively performing such measurement on the stator windings, it is possible to extract three periodic curves (SPCA, SPCB, SPCC) defining a zigzag curve (70) for accurately determining the rotor angular position.
