器件型号：DRV5055-Q1 对于我使用 的 TI 计算器磁感应接近工具、请提出一些问题。 当我将磁体类型从块更改为圆柱体时、数据会变得奇怪、这是正确的吗？

您好、Stefano、
感谢您考虑使用德州仪器。 这看起来像是您发现了某种错误。 您能否分享在输入菜单的数据设置下输入的内容？ 此外、您是否在 Excel 之外使用其他符号？ 例如、在"R"条目中、它看起来像"2.00"。 在 Excel 之外、您的典型符号是否为"2、00"？ 如果您在操作系统上使用 Excel 以外的其他数字表示法、您能否共享保存在.fem 文件中的模型外观？
当我运行您的圆柱体示例时、假设有1个扫描设置0.05网格因子、我得到以下结果：

您好、Stefano、
感谢您的提供。 您能否在 FEMM 中提供构造模型的图片？ 这是 FEMM 中的样子。 但是、我怀疑几何体或材料标签放置位置有问题、这会使您的构造模型看起来不同。 如果您的模型看起来与我的模型相同、那么它可能是在更改数字符号时无法正确转换的非空间属性之一。 由于您的操作系统已设置为"2、00"、因此 Excel 在与外部通信时将希望输出"2、00"。 但是、我认为 FEMM (用于气缸仿真)始终使用"2.00"、而不管您的操作系统使用什么符号。 遗憾的是、我的 IT 团队阻止我更改计算机上的语言区域设置以调试此问题。
我无法附加该文件、但如果您将上述代码放入.txt 文件中并将其重命名为.fem 、则可以复制该文件
