Practical Rotary Encoder Accuracy Limits for Transmission Error Measurement

Errors of angular position on encoders used for transmission error measurement were investigated to determine the practical limits of accuracy. Computer correction can be used to eliminate consistent errors on the encoders but errors remain, attributable to electrical noise, bearing errors and friction effects. Practical limits on the calibration and usage of the encoders for individual harmonics of once per revolution frequency and for a given angular position were established.
