Apparatus for generating magnetic flux of induction motor

Abstract

An improved apparatus for generating a magnetic flux of an induction motor, which is capable of more accurately generating a magnetic flux by operating a rotational coordinate system-based current and a phase of a magnetic flux for generating a reference magnetic flux, compensating a magnetic error value which is referred to a difference value between a reference magnetic flux and a really generated magnetic flux, which includes a stator magnetic flux generator for outputting a stator magnetic flux by operating a current of an inputted static coordinate system, a voltage of a static coordinate system, and a compensation voltage; a rotor magnetic flux generator for outputting a rotor magnetic flux by operating a current of a static coordinate system inputted to the stator magnetic flux generator and a stator magnetic flux outputted to the stator magnetic flux generator; a reference magnetic flux generator for outputting a reference magnetic flux by operating a current of an inputted rotational coordinate system and a phase of a magnetic flux; and a compensation voltage generator for generating a compensation voltage so as to compensate a magnetic flux error value which is referred to a difference value between a reference magnetic flux outputted from the reference magnetic flux generator and a rotator magnetic flux outputted form the rotor magnetic flux generator, and then for outputting to the stator magnetic flux generator.
