12槽10极的的无刷直流电机，用RMXPRT 计算好象有问题
本帖最后由 yzhangx 于 2019-2-27 10:27 编辑12槽10极的的无刷直流电机（集中绕组），用RMXPRT 计算好象有问题, 实际电机空载不到2000，计算结果有5000多，效率也很低，
不知道哪里搞错，帮忙看下，

你的极数怎么写的4极，小老弟
转子是10极的，写进去，出错了。只有2、4、6可选 yzhangx 发表于 2019-2-27 14:00

什么文件？电机有关参数吗？ 本帖最后由 zy1986 于 2019-3-4 14:07 编辑
你的电流密度50，再把你的样机参数和仿真模型对照下。叠厚、进角、匝数材料，仿真和实物不可能完全一致的，还是会有偏差的 本帖最后由 HC2019 于 2022-8-5 09:15 编辑
验证一下，楼主的原始文件输入数据应该还有错误，除了极数，还有Pole Arc.修正后计算结果效率还可以78%,空载2500rpm HC2019 发表于 2022-8-5 09:14
