  • Publication number: 20230408247
    Abstract: A rotation angle detection device includes at least one target rotating in unison with a shaft, a rotating member for rotating at a different rotation speed from the shaft as the shaft rotates, a first sensor whose output signal changes when the target is approached, a second sensor that detects the rotation angle of the rotating member within one rotation, and a computing section that calculates the absolute angle of the shaft based on the output signal of the first sensor and the rotation angle of the rotating member detected by the second sensor. The output signal of the first sensor changes at a period different from the rotation period of the rotating member when the shaft rotates, and the computing section detects the absolute angle of the shaft at that time from the rotation angle of the rotating member when the output signal of the first sensor changes.
