Modular Multi-Turn Gear Angular Position Encoder

Abstract

A simplification of the mechanism of an absolute multi-turn gear angular position encoder is proposed. Movement on the input measuring shaft is transmitted in parallel to several driven shafts and single-turn sensors located on the shafts. In this case the reading of the encoder may be calculated using methods of modular arithmetic from the readings of single-turn sensors based on the values of the parameters that determine the gear ratios of the encoder mechanism.
