摘要
The capacitive angle encoder contains a stator with at least two stator plates (4,6,8,10) at a distance apart, Rotor plates (5,7,9) are rotatably arranged between the stator plates and electrically conducting coatings (11-14) on the facing surfaces of the plates forming capacitances. At least one of the capacitances varies with the rotation of the rotor (2). One of the sides of the stator plate is accessible before sealing of the housing to enable adjustment of a correction capacitor (15). The correction capacitor is set up to correct for reproducible errors dependent on rotation angle. ADVANTAGE - Achieves high accuracy at relatively low manufacturing cost.
