Device for generating magnetic flux in induction motors

摘要

The device contains a stator magnetic flux generator (101) which produces a stator magnetic flux from the current and voltage of an entered static coordinate system and a compensation voltage. A rotor magnetic flux generator (102) outputs a rotor magnetic flux from a current of a static coordinate system entered into the static flux generator and a stator magnetic flux output to the stator flux generator. A reference magnetic flux generator (103) generates a reference flux from a current a current of an entered rotary coordinate system and one phase of a magnetic flux. A compensation voltage generator produces a compensation voltage to compensate a magnetic flux error between the reference and rotor magnetic flux values, with final output to the stator flux generator.
