For the clear specification of the electromagnetic processes in 3-phase AC machines and as a starting point for control design, equivalent circuits which are based on the representation of the physical quantities as complex space vectors in a stator-fixed coordinate system will be a very useful tool. A first starting-point and also a base for start values of a more exact estimation will be provided by the name plate or by the rated data of the motor. For a more exact parameter setting off-line identification methods which provide estimated values of motor parameters during a test run in standstill are discussed.
