要約(英語): The optical rotation angle sensor is characterized in that it is excellent in resolution and angle detection accuracy, and the magnetic sensor is characterized in that it is resistant to foreign matter such as dust and dirt, and that it is possible to achieve low power consumption, small size, and low cost of the sensor, as compared with the optical sensor. However, in the magnetic type, in order to obtain a high resolution as compared with the optical type, it is necessary to make the magnetization period of the magnet fine, so the magnetic rotation angle sensor has the difficulties compared with the optical type.This time, for magnetic rotation angle detection, we carried out a feasibility study by magnetic field simulation and principle verification experiments on a technique of extracting signals of two frequencies from one signal detection track by modulating a magnetic field from a magnet with a slit of a magnetic material, and this paper reports the result.
