Abstract
PURPOSE: To take the electrical lead-out line from the electrode plate only from the fixed-side electrode, by a constitution where the first electrode plate having the first electrode on the surface and the second electrode plate having the second and the third electrodes separated electrically from each other on the surface are made opposite to each other to form a capacitor.
CONSTITUTION: The first electrode plate 22 having the first electrode 24 on the surface is fixed to rotation axis 45 of motor 44, and the second electrode plate 43 having the second electrode P1 and the third electrode P2 separated electrically from each other on the surface is fixed to fixing part 45 oppositely to the first electrode plate 22, and these electrodes are so constituted that the area of the second electrode P1 opposite to the first electrode 24 may be approximately equal to the area of the third electrode P2 opposite to the first electrode 24. The change signal of the electrostatic capacity value between terminals which is led out electrically from the second and the third electrodes P1 and P2 is used as the rotation speed signal of motor 44 when motor 44 is rotated, so that driving control can be always performed in a fixed speed.
