Patent ID: 7330010

Claim:
A method for operating a rotating electrical machine, which machine has at least two sets of stator windings (A, B) and each set of stator windings (A, B) comprises n phase windings, where n≧3, in each case one associated converter unit being provided for each set of stator windings (A, B), in which the respective set of stator windings, (A, B) is fed by the associated converter unit, wherein the currents (i A1 , i A2 , i A3 , i B1 , i B2 , i B3 ) of at least n−1 phase windings of each set of stator windings (A, B) are measured, wherein in each case one associated regulating device is provided for each converter unit and each converter unit is driven by means of a drive signal of the associated regulating device independently of regulating devices of the respective other converter units, and wherein the drive signal (S) is formed in the respective regulating device from the measured currents (i A1 , i A2 , i A3 , i B1 , i B2 , i B3 ) of each set of stator windings (A, B).
