This paper deals with an optimal angle error reduction method of magnetic position sensor using hall effect elements. The angle detection simulation for the magnetic position sensor is perfo rmed by 3 dimensional finite element method and Taguchi method, one of t he design of experiments. The magnetic position sensor is required to ge nerate ideal sine and cosine waveforms from its hall effect elements according to rotation angle for precise angle information. However, the output signals are easy to include harmonics due to uneven magnetic field distribution from permanent magnet in the air-gap in the vic inityof hall effect elements. For the Taguchi method, three design p arameters related to position of hall effect elements and shape of bac k yoke are selected. The characteristics of optimal magnetic position s ensor are compared with those of original onein terms of simulation a s well as experiment. Finally, the performances of the motor adopting original model and optimal model are represented for the purpose of verification of motor performance due to signals from magnetic position sensor.
