Abstract
To improve the detection limit of a wheel speed without improving the performance of a processor in a rotating device.SOLUTION: The rotation device 10 includes the sensor device 40 having the first sensor rotor 43 and the second sensor rotor 44 that rotate integrally with the hub shaft 31, and the first sensor 41 and the second sensor 42, and the processing device 50, and the processing device 50 includes the absolute angular speed calculation unit 56 that obtains the absolute angular speed ω 1 from the absolute angle α obtained from the first electrical angles θ 1A and θ 1B, and selects the absolute angular speed ω 1 as the angular speed used for calculating the wheel speed signal when the wheel speed is in the high speed range. And the switching unit 58 configured to select the relative angular velocity ω 2 calculated based on the electrical angular velocity ω e as the angular velocity used for calculating the wheel speed signal when the wheel speed is in the low speed range.SELECTED DRAWING: Figure 4
