ABSTRACT:
In accordance with certain embodiments, the present technique provides a reduced current field-oriented-control scheme. For example, the present technique provides a method of controlling an induction device in which a predetermined reduction factor is employed to reduce the flux-current vector of a field-oriented-control scheme. By reducing this vector, less current and less power are drawn by the induction device, in turn reducing resistive heating and stator core losses, for instance.
