Filed: 2017-08-08
Abstract: To achieve a structure capable of improving the measurement accuracy of torque and the degree of freedom in design.SOLUTION: The number of poles of a first encoder is made smaller than that of a second encoder. The phase difference between the output signal of a first sensor 4a facing the first encoder and the output signal of a second sensor 4b facing the second encoder is determined. A correction value is obtained by removing a periodically varying component from a phase difference ratio by an adaptive filter, and a torque transmitted by the rotation shaft is calculated on the basis of the correction value. Here, the phase difference ratio is a value obtained by dividing the phase difference by the period of the output signal of a first sensor 4a.SELECTED DRAWING: Figure 2
