在这个博客我找到了 Thomas Söll 绘制的变压器 3D 图纸。
经过一些更改后，我得到了以下代码：
\documentclass{article}
\usepackage{pst-solides3d}
\usepackage{expl3}
% Parameters.
\def\radius{1.11}
\def\windingsOne{32}
\def\windingsTwo{64}
% Activating floating point calculation.
\ExplSyntaxOn
\cs_new_eq:NN
\calc
\fp_eval:n
\ExplSyntaxOff
% Constants.
\def\factor{\calc{5*\windingsTwo}}
\def\lengthA{\calc{2*pi*\windingsOne/\factor}}
\def\lengthB{\calc{2/5*pi}}
\def\vertDist{\calc{3/4*pi}}
\def\thickness{\calc{16/(25*\windingsTwo)}}
% Global setup.
\psset{%
viewpoint=20 5 15 rtp2xyz,
lightsrc=20 60 60 rtp2xyz,
Decran=30
}
\psset{%
solidmemory,
algebraic
}
% Objects with predefined options.
\newpsobject{core}{psSolid}{%

}
\newpsobject{wire}{psSolid}{

r=\thickness,
linewidth=0.5pt,
linecolor=red!60,
incolor=red!60,
fillcolor=red!60,

ngrid=727 30,
action=none
}
\newpsobject{connect}{psSolid}{
object=fusion,
linecolor=gray,
grid=false,
action=draw**
}
\pagestyle{empty}
\begin{document}
\begin{figure}[htbp]

\begin{pspicture}(-3,-3)(8,8)
% --------------- Core ---------------
\core[a=1,b=5,c=1,action=draw**,name=H1](0,1.5,-0.5)

\core[a=1,b=1,c=3,action=none,name=H3](0,3.5,1.5)
% --------------- Wire ---------------
{\defFunction{helixA}(t){\radius*cos(\factor*t)}{\radius*sin(\factor*t)}{\vertDist*t}
\wire[function=helixA,range=0 \lengthA,name=wire1](0,-0.5,0)}%
{\defFunction{helixB}(t){\radius*cos(\factor*t)}{-\radius*sin(\factor*t)}{\vertDist*t}
\wire[function=helixB,range=0 \lengthB,name=wire2](0,3.5,0)}%
% ------------- Assembly -------------
\connect[base=H2 wire1]
\connect[base=H3 wire2]
\composeSolid
\core[a=1,b=5,c=1,action=draw**,name=H4](0,1.5,3.5)
\end{pspicture}
\end{figure}
\end{document}
\factor我的问题是，常数、\lengthA、\lengthB、\vertDist和的值\thickness是手动找到的。有人能告诉我，如果它们应该取决于变压器铁芯周围的绕组数，那么它们到底应该是多少吗？
PS 代码需要很长时间（在我的计算机上大约 1 分钟）来编译，所以如果有人可以告诉我如何缩短编译时间，请告诉我！

首先：创建最小示例！在这里，您是否会说丹麦语并不重要！
