| Summary: | 碩士 === 正修科技大學 === 機電工程研究所 === 96 === The starter motor is a key component in the ignition process of an automotive. If the start motor fails, the automotive will lose its ability to power on. The start switch of the start motor is referred to as the electromagnetic switch. Many of the problems of the start motor can attribute to the malfunction of the electromagnetic switch. For example, insufficient pull force controlled by the electromagnetic switch will stop the start process of the start motor. To investigate the performance of the electromagnetic switch, The Taguchi method is utilized in this study. The characteristics of the electromagnetic switch are listed and classified into different factors with different levels. Some of the factors are controllable, and the others are uncontrollable. Using the Taguchi method, the factors are organized into an orthogonal array. Then, the combination of different levels of the factors is evaluated by experiment to investigate its influence on the electromagnetic switch. The experimental results are collected and analyzed for the improvement on the electromagnetic switch performance.
