一场上线事故后，他被指认为责任人。署名被删，股份被收，行业封杀。妻子 kiko 在事故报告上签下名字，从此他只能穿着后勤围裙，留在自己亲手创建的公司里端菜。
三年后，滕壮壮踩着他的旧方案成为首席架构师。庆功宴上，kiko 又在全体董事面前签下离婚与责任切割协议。
在别处也签了。
就在最后一笔落下时，一百二十七家门店同时黑屏，每分钟损失十二万。所有人都求滕壮壮救场，又等着看这个“罪人”被赶出最后一扇门.............]]></description><category></category></item><item><title><![CDATA[为什么能够确定转子的位置呢]]></title><link>https://blog.youkuaiyun.com/ElseWhereR/article/details/154400170</link><guid>https://blog.youkuaiyun.com/ElseWhereR/article/details/154400170</guid><author>ElseWhereR</author><pubDate>Wed, 05 Nov 2025 10:25:19 +0800</pubDate><description><![CDATA[PMSM转子的永磁体的磁铁在转子中的位置是固定不变的，因此，转子机械位置 → 永磁体磁链方向（ψ_f）→ 通过磁路结构形成方向相关磁特性 → 体现为电感/阻抗差 → 被测得并用于推回转子角度。]]></description><category></category></item><item><title><![CDATA[HFI与坐标轴]]></title><link>https://blog.youkuaiyun.com/ElseWhereR/article/details/154385539</link><guid>https://blog.youkuaiyun.com/ElseWhereR/article/details/154385539</guid><author>ElseWhereR</author><pubDate>Tue, 04 Nov 2025 16:07:26 +0800</pubDate><description><![CDATA[若存在误差 Δθ = θe − θ̂e，则注入方向与真正的 d 轴存在偏差，高频磁化路径会“看到”一个混合的 d、q 轴成分。目标就是通过闭环控制，使得当 Δθ = 0 时，注入矢量恰好与真实 d 轴重合，分解结果的 q 分量理想值为 0，只剩纯 d 分量。短暂的注入稳定的直流电，定子产生一个稳定的磁场，此时转子的位置就会变化，转子的N就会被定子产生的S吸引，保持同向，此时的d轴与α夹角的角度就是估算角度。注意，此时只是瞬间确定转子的位置，如果外力稍微扭动转子，那么转子的位置就又不确定了。]]></description><category></category></item><item><title><![CDATA[pmsm的启动堵转和运行堵转]]></title><link>https://blog.youkuaiyun.com/ElseWhereR/article/details/154342063</link><guid>https://blog.youkuaiyun.com/ElseWhereR/article/details/154342063</guid><author>ElseWhereR</author><pubDate>Mon, 03 Nov 2025 16:15:18 +0800</pubDate><description><![CDATA[topic: pmsm的启动堵转和运行堵转。]]></description><category></category></item><item><title><![CDATA[永磁同步电机工作原理]]></title><link>https://blog.youkuaiyun.com/ElseWhereR/article/details/153462782</link><guid>https://blog.youkuaiyun.com/ElseWhereR/article/details/153462782</guid><author>ElseWhereR</author><pubDate>Fri, 17 Oct 2025 11:32:23 +0800</pubDate><description><![CDATA[Permanent Magnet Synchronous Motor, PMSM for short, has rotor and stator.
