摘要： An optical encoder device is provided, in which the number of light transmissive slits of a stationary slit plate can be increased as much as possible according to the length of a light receiving surface of a light receiving element to produce an output signal with little distortion. A movable slit plate 3 includes a slit row R1 in which a plurality of light transmissive slits (light transmissive portions) S1 each having a slit width of 180° in terms of electrical angle and a plurality of light non-transmissive slits (light non-transmissive portions) S2 each having a slit width of 180° in terms of electrical angle are alternately formed. A stationary slit plate 4 includes a slit row R2 in which a plurality of light transmissive slits S3 each having a slit width of 180° in terms of electrical angle and a plurality of light non-transmissive slits S4 each having a slit width of (360Xk-180)° in terms of electrical angle are alternately formed. k is a value that satisfies k=1±(⅓n) where n denotes the number of the light transmissive slits S3.

摘要： A resolver detected position compensation system for a resolver is provided that can enhance a position detection precision by performing a further compensation on a compensated position that was obtained from a static error compensation. The position detection circuit outputs a compensated detected position signal in which a static error has been compensated. The differential circuit differentiates the compensated detected position signal to obtain a rotational speed of the resolver. Based on a signal representing the rotational speed output from the differential circuit, the phase data memory device and the peak value memory device send the variation in phase and the amplitude peak value, respectively, of the dynamic error signal to the multiplication device. The multiplication device calculates an estimated dynamic error and the subtraction circuit removes the estimated dynamic error from the compensated detected position signal.
