PURPOSE:To provide a detector which requires less torque for a revolving shaft, has good linearity and maintains stable parallelism between a rotor and a stator without requiring any special linearizing mechanism by having the rotor and the stator, providing electrodes for impressing voltage on the stator near the outside edge thereof and electrodes for drawing out voltage on the stator near the inside edge thereof, and disposing the electrodes for impressing voltage and the electrodes for drawing out voltage. CONSTITUTION:A rotor 1 is a conductor consisting of two sheets of the same sector plates 1a, 1b which have the same center and 90 deg. central angle and are disposed symmetrically. The shaft 2 of the rotor 1 penetrates in the central part of an immobile stator 3. The stator 3 is provided with electrodes 3a, 3b for impressing voltage which are bisected to a toric shape on a base plate 4 near the outside edge thereof. The stator is also provided with electrodes 3c, 3d for drawing out voltage which are bisected to a toric shape on the base plate near the inside edge thereof. Both electrodes are so disposed that the parting line of the electrodes 3a, 3b intersects orthogonally with the parting line of the electrodes 3c, 3d. |
