The surface of the rolling element and the orbital plane might cause corrosion with the tire of the bearing when the potential difference is privately caused and it become damage. Thus, the phenomenon of damaging the bearing by the influence of the current is called a stray current corrosion. The bearing for the railway vehicle and the damage case with the ball bearing for a small motor are chiefly reported. The motor of the running total velocity rotation is developed, and there is a lot of demand, too. Then, the experiment in the high-speed rotation region (1800 rpm or more) to the stray current corrosion is needed. The development of the device that can correspond to the high-velocity revolution is a purpose because it cannot correspond to the high-velocity revolution in a present pilot machine. In a past device, the housing part was L character type and situation like overhang mounted impeller. It was made a box type and it made it to the situation of tael. It was stopped to connect with the belt pulley and to drive three axes, and installed the motor in each one of the axis. To confirm the rigidity of the device, the vibration value by 1800 rpm, 3600 rpm, and 5400 rpm is measured by no energizing. As the result, the vibration value decreased by developing the testing set, and the amplitude was able to be stabilized.
