Circuitikz 中的三相电机

Question

我想绘制一个具有三个连接的三相交流电机的符号，类似于 Plecs 所做的：

我认为我可以手动完成，Circuitikz 有没有更快的选择？

Answer 1

为了让您入门，请看以下代码：我在圆圈上添加了边框锚点，并在形状上添加了一个锚点elmech（将在未来的版本中做出类似的更改，这些锚点很有用）。（更改在 之间%%%，代码取自pgfcirctripoles.tex）。

将形状更改为与您的绘图相似应该很容易（但如果您这样做，请重命名它）。

Answer 2

除了 Rmanos 方法之外，这是我的版本。现在上面有锚点，但无论如何它还是有用的。

\documentclass[border=10pt]{standalone}

\usepackage[pdftex]{graphicx}           %% Grafikeinbindung
\usepackage{circuitikz}

\begin{document}
    \begin{circuitikz}
            \draw (-5, 0) circle (1cm);
        \node [draw, thick, shape=rectangle, minimum width=0.4cm, minimum height=1.2cm, anchor=center] at (-5,0) {};
        \draw (-5.2, 0.4) to (-4.8, 0.4);
        \draw (-5, 0) ++(210:1cm) -- ++ (-0.2, -0.5) -- ++ (0, -0.5) -- ++ (2, 0); 
        \begin{scope}[yscale=1,xscale=-1]
            \draw (5, 0) ++(210:1cm) -- ++ (-0.2, -0.5) -- ++ (0, -0.5) -- ++ (2, 0); 
        \end{scope}
        \node[color=black, below] at (-5,-1.5) {PMSM};
    \end{circuitikz}
    %electrical machine
