A simple understanding of field-orientation for AC motor control
E.S. Tez · 1995
In the AC motor field, vector has now become a grossly abused term causing confusion e.g. as to whether it signifies an alternative to pulse-width-modulation (i.e. DC-to-AC power conversion) or a technique for AC motor torque control. To emphasise the latter meaning, the term control is now widely accepted, but the confusion still continues with phrases like 'sensorless flux-vector control'. Hence, the term is used here in an attempt to provide a simple understanding of field-orientation for AC motor control.
