In recent year, sensors have come to require high resolution and accuracy because of the progress of control technology. Magnetic encoders are widely used in servo motors in factory automation, because of there suitability for use in difficult environments. Reseach on efficiency tends to favor the use of a magnetic simulation method. However, this requires complex calculations and much time. Therefore, a simplified simulation method has been deveroped and used. In this paper, to obtain an idea index phase signal, a new magnetization pattern is proposed and calculated by using the developed simulation methos, named the superposed magnetizing method. The experimental results showed that by expanding the detection gap it is possible to obtain a highly accurate index phase signal.
