At this time, the electrodes 3e to 3f
The timing of switching to the electrode 3a is delayed from the timing of switching from the electrode 3a to the electrode 3b by a fixed time, for example, 0.5 seconds. Therefore, an extra voltage is applied to the electrode 3e for a longer time than the electrode 3a, for example, 0.5 seconds.

Voltage is switched from the electrode 3c to the electrode 3c and from the electrode 3f to the electrode 3g. The timing of switching from the electrode 3f to the electrode 3g is similarly delayed because the switching timing is delayed.

Example 7 The rotation speed when a direct current voltage of 5.0 kV was applied was measured in the same manner as in Example 3 except that dimethyl phthalate was used as the working medium. The rotational motion immediately after the voltage application showed a rotational speed of 35.7 seconds / revolution, but thereafter the rotational motion became unstable, and it was also observed that the rotational speed suddenly decreased. Current value during voltage application is 0.1

And 3e were used as a positive electrode, electrodes 3b and 3f were grounded and used as a negative electrode, and a direct current of 5.0 kV was applied, and the rotation direction and rotation speed during application were measured. The results are shown in Table 5. Further, instead of the electrodes 3b and 3f, the electrodes 3d and 3h were used as negative electrodes, and similarly, the rotation direction and the rotation speed during voltage application were measured, and the results are shown in Table 4. The current value when voltage was applied was 0.05 mA or less, which is below the lower limit of the measurement limit of the current measuring device used in each case.
