ROTATING ANGLE DETECTION DEVICE USED CAPACITIVE CHANGE AND METHOD THEREOF

摘要

This invention can increase the resolving power of the rotating angle using the rate of capacity change between two objects. The objective is to provide a rotating angle detecting device using capacitive change that is small in size and costs low to manufacture. The method to reach the above objective is a rotating angle detection device with a stator with two fixed conductor plates; and a rotator with a rotating conductor plate that rotates relatively to the above stator, with every rotation overlapping and passing the above fixed conductor plates repeatedly with different area change.
