Abstract  An error compensation method for the single pair-pole encoder is studied. For each of the single-pole magnetic encoder, analyzed offset, sensitivity error, quadrature error and ferromagnetic interference error, the expression of each error is obtained. In order to facilitate the error compensation,  the expression to describe the error common to this type  is summed up. The formation process of the error can be assumed as the process of changing from circle to ellipse. Therefore the inverse of this process is the same as the process of error compensation. The experimental results show that the accuracy of magnetic encoder which used this method could reach 0.02°, thus the error compensation effect is obvious. The advantages of the magnetic encoder which is applied this method are low-cost, high-precision and convenient to use.
