PROBLEM TO BE SOLVED: To provide a torque ripple measuring device for measuring the torque ripple data depending on an angle generated by a motor without being influenced by friction or the like independently from the torque ripple increased in proportion to the torque ripple independent of the generated torque of the motor. SOLUTION: This measuring device includes a learning control device 2 for repeatedly correcting the control input so that a motor is rotated at a constant speed and finally realizing the constant-speed drive, taking a torque command, a speed command or a position command as the control input, and memories 4, 5 for collecting the torque command data Tr (θn) (N=1, 2, ..., N) corresponding to the motor angle (0 deg.<=θn<360 deg., n=1, 2, ..., N) for one rotation during constant speed rotation realized by the learning control device 2, and determine the torque ripple data from the torque command data by an operating device 3 and store the same.
