Abstract

The method involves a control and regulating circuit (5) determining a stator voltage vector, measuring the stator winding current vector, deriving an estimated or model stator flux vector from the current and voltage vectors, deriving a stator curren vector demand value from the flux vector and feeding to a current regulator with the actual stator current vector. The current regulator produces a value for the stator voltage vector so that the stator current is regulated to the demand value. An Independent claim is also included for a converter with a control and regulating unit.
