Optimization of magnetizing parameters for multi-pole magnetic scales by Taguchi method

Abstract

This research focuses on optimization of parameters for magnetizing patterned magnetic scale to match the application of precision control.The results are potential to fabricate a magnetized multi-pole magnetic scale with high quality magnetic field. This method leads to improve the quality and cost in designing magnetizing parameters. As a result of using the optimal solution, the Bz enhancement is achieved by a factor of 1.17x and the decrease in SD is 0.4x. The high reproducibility factor is evidenced from SD/Bz, which is 0.006x (5.6/842.7). The high quality field through the detection gap control is beneficial for signal processing. The effects of magnetization parameters will be further elaborated in details.
