For the structure of the motor, it repeats fine acceleration and deceleration such as in a constant speed. Because of this, it would cause revolution fluctuation and vibratory forces. The vibratory forces of the motor cause the vibration and the noise. In order to measure the vibratory forces, the rigid-body vibration needs to be measured, and we make the motor to be free support. However, depending on the size of the motor, it is difficult to make it be free support. In this study, we formulate a way to measure the vibratory forces of motor without free support and aims to establish it through experiments. In this measurement method which was invented, there is a possibility for practical use.
