The purpose of the present invention is to provide a torque command generation device for generating a motor-generated-torque command that makes it possible to maximize excitation force while ensuring necessary acceleration, and the like, within a limited motor torque range. A torque command generation device (6) is provided with: a maximum torque calculation unit (633) for calculating, according to a motor speed, a maximum torque value for a motor-generated-torque-command signal value; a DC component limiter (635) for calculating a DC signal value; a surplus amplitude calculation unit (637) for calculating a surplus amplitude by subtracting the maximum torque value from the sum of the DC component value calculated by the DC component limiter (635) and an externally input excitation amplitude; a sine-wave transmitter (639) for generating a sine wave having an amplitude obtained by subtracting the surplus amplitude from a base amplitude; and a summing unit (640) for calculating the motor-generated-torque-command signal value by adding the DC component value and the sine wave value.
