Abstract: The measurement theories for rotational inertia were summarized,including single pendulum method,mass line method and falling method.The reasons for the inaccuracy of the permanent magnet rotor of micromotor underaloover-mentioned measurements were analyzed. Demagnetization method and shielding geomagnetic method were proposed. The demagnetization method was verified by experiment, and the shielding geomagnetic method was analyzed.

Key words: rotator inertia, permanent magnet rotor, measurement
