METHOD TO OPERATE ELECTRIC ROTATING MACHINE, AND EQUIPMENT TO IMPLEMENT ITS METHOD

PROBLEM TO BE SOLVED: To provide a method to operate an electric rotating machine (1). SOLUTION: Currents (iA1, iA2, iA3, iB1, iB2 and iB3) of windings of at least an (n-1) phase of each set of stator windings (A, B) are measured in order to enable to adjust redundantly and independently electric variables of each set of the stator windings of the electric rotary machine, and at each converter unit (2), corresponding one adjusting device (3) is provided, respectively. Each converter unit (2) is driven by a drive signal (S) of the adjusting device (3) independently from the adjusting device (3) of the other converter unit (2). In addition to this, the drive signals (S) are formed of the measured currents (iA1, iA2, iA3, iB1, iB2 and iB3) of each set of the stator windings (A, B) in each adjusting device (3). Moreover, equipment to implement the method is included. COPYRIGHT: (C)2007,JPO&INPIT
