An induction motor control apparatus for controlling an operation of an induction motor by controlling an operation of an inverter apparatus that converts direct-current power into alternating-current power and supplies the alternating-current power to the induction motor, wherein the induction motor control apparatus is configured: to deactivate the operation of the inverter apparatus after an operation in which the induction motor control apparatus controls the inverter apparatus to output a zero voltage to the induction motor for a predetermined time, such that a magnetic flux in the induction motor is caused to decay before the operation of the inverter apparatus is deactivated; to control a voltage command for the inverter apparatus in a period before the inverter apparatus outputs the zero voltage and before the inverter apparatus starts a decrease in a torque current and an excitation current for the induction motor, whereby the voltage command for the inverter apparatus is calculated using a calculation equation including a first time constant calculated from a secondary resistance (R2') of the induction motor and a secondary self-inductance of the induction motor as parameters; and to control the voltage command for the inverter apparatus in a period after the start of the decrease in the torque current and the excitation current and until the torque current and the excitation current become zero such that the zero voltage is output by the inverter apparatus, whereby the voltage command for the inverter apparatus is calculated using the calculation equation, wherein the first time constant included in the calculation equation is changed to a second time constant calculated from a resistance value (Rσ) converted to the primary side of the induction motor and a leakage inductance value (Lσ) converted to the primary side of the induction motor. to deactivate the operation of the inverter apparatus after an operation in which the induction motor control apparatus controls the inverter apparatus to output a zero voltage to the induction motor for a predetermined time, such that a magnetic flux in the induction motor is caused to decay before the operation of the inverter apparatus is deactivated; to control a voltage command for the inverter apparatus in a period before the inverter apparatus outputs the zero voltage and before the inverter apparatus starts a decrease in a torque current and an excitation current for the induction motor, whereby the voltage command for the inverter apparatus is calculated using a calculation equation including a first time constant calculated from a secondary resistance (R2') of the induction motor and a secondary self-inductance of the induction motor as parameters; and to control the voltage command for the inverter apparatus in a period after the start of the decrease in the torque current and the excitation current and until the torque current and the excitation current become zero such that the zero voltage is output by the inverter apparatus, whereby the voltage command for the inverter apparatus is calculated using the calculation equation, wherein the first time constant included in the calculation equation is changed to a second time constant calculated from a resistance value (Rσ) converted to the primary side of the induction motor and a leakage inductance value (Lσ) converted to the primary side of the induction motor.
