本文主要研究的目的是提高测速传感器的精度，通过感应元件与被测齿轮之间的距离进行优化。主要通过Ansoft Maxwell软件来仿真不同距离的感应元件的磁场强度和实验数学建模这两种方法，将得到的距离值进行分析比较，进而得到在误差可控范围内的最优值。%The main purpose of this research is to improve the speed sensor accuracy is optimized through the sensing element and the measured distance between the gears. Mainly through simulation software Ansoft Maxwell magnetic field and experimental mathematical modeling sensing element of these two methods at different distances from the values obtained were analyzed and compared, and then get the best value controlled within the error range.
