Correlation between Optimum of MR Element Slant Angle and the Ratio of MR Element Length to Magnetic Pole Length on Linear Magnetic Encoder

摘要

Correlation between optimum of MR element slant angle and the ratio magnetic pole length of to magnetoresistance element length on linear magnetic encoder is explored in this paper. Optimum slant angle of MR element is different and increases in proportion to the ratio of magnetic pole length to MR element length by slant multi-phase filtering model.
