摘　　要：为了减轻热处理过程对VSM1068微型步进电动机外壳磁性能的影响,采用阶梯式热处理工艺方法,利用金相显微镜和数值分析工具进行分析,获取材料金相组织、热处理温度、热处理气氛对微型步进电动机外壳磁性能的影响规律,以探索提高微型步进电动机性能的途径。试验数据分析结果表明,真空气氛900℃加热保温2 h的热处理工艺对改善电动机外壳的磁性能效果最显著。In order to alleviate the influence of heat treatment process on the magnetic properties of the shell of the VSM1068 micro stepper motor,the stepped heat treatment process method is used to analyze the metallographic microscope and numerical analysis tools to obtain the influence of the metallographic structure,heat treatment temperature and heat treatment atmosphere on the magnetic properties of the micro stepper motor casing,so as to explore the way to improve the performance of the micro stepper motor.The results of experimental data analysis show that the heat treatment process of heating and holding at 900°C for 2 h in vacuum atmosphere has the most significant effect on improving the magnetic properties of the motor casing.
