摘要
为了减少微电机临界转速对电机的危害,对微电机转子临界转速计算方法进行了研究。以分析法为基础设计了适合各种类型的微电机转子临界转速的计算程序,介绍了计算程序考虑各种主要因素。以轴承支承类型设计了两种转子支承夹具,对样品进行了频率响应测试。实验测量结果显示,两种支承计算和测试数据误差在10%以内。由此可见,该计算程序可以计算各种类型微型电机转子,对工程实践具有重要的指导意义。
In order to reduce the damage of critical speed for micromotor,make research on the calculation method of critical speed for micromotor.Based on analytic method,the calculation program is designed,which is suitable for all kinds of rotors.The main factors are introduced for calculation program.Two kinds of fixture were designed based on the kinds of bearing.The frequency response test for samples is done.The test result shows that the datum error is below 10 percent between calculation and test for two kinds of supports.The calculation program can be suitable for all kinds of rotors of micromotor.It is helpful to engineering practice.
