ABSTRACT OF THE DISCLOSURE: This invention relates to an induction motor magnetic flux control method and apparatus in a vector control device in which a primary current is supplied to the induction motor in response to an excitation current command value and a torque current command value and the frequency is controlled as a function of the magnetic flux calculated from the voltage and current applied to the motor, in which the magnetic flux is calculated as a function of the voltage, current of the motor and a magnetic flux command signal by using a primary delay circuit, the time constant of the primary delay circuit is set equal to that of the secondary circuit of the motor. According to this invention, it is possible to minimize the phase error with respect to the true secondary magnetic flux included in the secondary magnetic flux value, which leads to an accurate torque control.
