  • Patent number: 10041821
    Abstract: In an indicating-needle type meter device, when starting excitation of a stepping motor, a controller sets the phase of an excitation signal to a predetermined excitation start position and returns the phase of the excitation signal by a predetermined reversal angle such that an indicating-needle rotates in the backward direction, thereby positioning the indicating-needle at a stopper position. Subsequently, the controller advances the phase of the excitation signal by an origin return angle to rotate the indicating-needle in the forward direction to an origin position apart from the stopper position by a predetermined angle, thereby positioning the indicating-needle at the origin position. Here, the origin return angle is an angle obtained by adding a backlash angle, a predetermined positive pre-offset angle, and a positive placing error correction angle set based on a placing error of the indicating-needle with respect to the stopper.
