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 is provided with: a maximum torque calculation unit for calculating, according to a motor speed, a maximum torque value for a motor-generated-torque-command signal value; a DC component limiter for calculating a DC signal value; a surplus amplitude calculation unit for calculating a surplus amplitude by subtracting the maximum torque value from the sum of the DC component value; a sine-wave transmitter for generating a sine wave having an amplitude obtained by subtracting the surplus amplitude from a base amplitude; and a summing unit for calculating the motor-generated-torque-command signal value.
