4、n soft作为世界领先的电磁有限元分析软件，Maxwell已广泛应于电气设备行业，RMxprt作为Ansoft最重要的一个模块，广泛应用在工程电磁场， 它可以优化前期项目的设计。然后我们可以生成一个合理的2 d / 3 d有限元分析模型。可自动加载几何和自动定义的各个部分材料，给电动机的边界条件时， 励磁电源等等。在本设计报告中，我们利用An soft Maxwell进行建模。详细分 析步骤和过程，根据给定的设计参数结合上课所学习的知识， 在An soft Maxwell 14中进行仿真和计算，来验证电机设计的合理性。四设计分析根据给定的设计数据，经过一系列的计算，为后续进行仿真设计打下了基

5、础， 三相异步电动机电机设计是个复杂的过程， 需要考虑的因素、确定的尺寸和数据 很多。与单相异步电动机相比，三相异步电动机运行性能好，并可节省各种材料。 根据转子结构分类，可分为笼式和绕线式，本设计选择的是笼型感应电动机设计， 其转子的异步电动机结构简单、运行可靠、重量轻、价格便宜，得到了广泛的应 用，其主要缺点是调速困难。三相感应电动机作电动机运行时，转子的转速低于旋转磁场的转速，转子绕 组因与磁场间存在着相对运动而感生电动势和电流，并与磁场相互作用产生电磁转矩，实现能量变换。电磁设计主要的内容是确定电机的电磁负荷及定子两套绕 组的极对数。仿真设计时需注意以下几点：(1)负载的性质明确负载需

6、要恒功率调速或恒转矩调速，或在整个调速范围内部分转速区为恒 功率、部分转速区为恒转矩。(2)调速范围确定电机的常用转速区间和最大转速区间，以便选择合适的电机数据(3)通风冷却系统在设计时应兼顾电机各方面性能的要求， 根据不同的情况采取不同的方法，整个 电磁计算中的几个主要部分包括：主要尺寸与气隙的确定；定转子绕组与冲片设 计；工作性能的计算；起动性能的计算等。五仿真设计双击桌面的Maxwell 16.0，运行Maxwell软件，进入如下界面，点击菜单栏中PrmpeftE 冷qedJ1 RMMlOewqnl - MdcJne厂 Stn hl44u的，新建电机设计ITBA I h IPUI-I !
