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.

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 5 outputs a compensated detected position signal in which a static error has been compensated. The differential circuit 11 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 11, the phase data memory means 15 and the peak value memory means 17 send the variation in phase and the amplitude peak value, respectively, of the dynamic error signal to the multiplication means 19. The multiplication means 19 calculates an estimated dynamic error and the subtraction circuit 21 removes the estimated dynamic error from the compensated detected position signal.

A first cycle determining section 27 utilizes data stored in a fourth angle data storing section 23 to determine in which cycle of m cycles of the fourth angle data, fifth angle data, which has been newly computed in response to rotation of a rotary shaft 1, occurs. A second cycle determining section 29 determines in which cycle of n cycles of first angle data that occur in first determined cycle, the newly computed fifth angle data occurs. A third cycle determining section 31 determines in which cycle of N1 cycles of the first angle data, the current first angle data occurs, based on the first determined cycle and second determined cycle. An absolute position determining section 33 determines the absolute position based on third determined cycle and the digital value of the current first angle data.

摘要： A batteryless absolute encoder determines the accuracy of absolute position information to be output when electric power is turned on and outputs an alarm signal in the case of abnormality. The batteryless absolute encoder includes an absolute position computing section, an absolute position storing section, and a determining section. The absolute position computing section computes the absolute position of a spindle to be detected, including the number of revolutions of the spindle, on the basis of detection signals output from four reluctance resolvers. The absolute position storing section stores the absolute position output from the absolute position computing section when electric power is turned off. The determining section compares an absolute position output from the absolute position computing section when electric power is turned on and the stored absolute position and outputs an alarm signal if a difference between the two absolute positions is larger than a predetermined value.
