  • Method for determining rotor position angle of synchronous machine
    Patent number: 7067997
    Abstract: A method for determining a rotor position angle of a synchronous machine, the method comprising the steps of determining inductances (LA, LB, LC) of the synchronous machine in stator phase directions; generating an inductance vector (L) on the basis of the determined inductances (LA, LB, LC); and determining the rotor position angle (qr) on the basis of the determined inductance vector angle.
    Type: Grant
