Calibration method for rotational angle calculation device, calibration device for rotation angle calculating device, rotation angle calculating device, motor control device, electric actuator product, and electric power steering device
In the calibration method, the rotation angle calculating apparatus (20, 30) rotates based on the detection signal of the sensor θ C is calculated (S2) θ The rotational angle data Da indicative of C is transmitted to the calibration apparatus (40) (S3), and the time difference data DT relating to the time difference between the detection of the detection signal and the transmission of the rotational angle data is transmitted to the calibration apparatus (S3).Calibration deviceAngle of rotation θ R is measured (S1).Angle of rotation θ The measurement time TM measured by R andThe rotational angle data has measured or transmitted the time of communicationS4)The angle of rotation measured at time TC2 from the communication time TT just before the time difference between the detection signal and the transmission of the rotational angle data θ AndBy comparing the rotation angle data Da withThe calibration data DC of the rotation angle data is obtained (S5S6)
