| Abstract |
Taking the equation of motion into account in a sensorless induction motor drive reveals
an apparent saliency in the motor impedance that is linked to the rotor flux orientation. The saliency
phenomenon can be explained based on the standard space-vector model of the motor, and it can be
used for sensorless rotor flux angle estimation down to zero speed and stator frequency. |
