I'm trying to draw an diagram of an induction machine like this: Cross-section of an electric machine circuit

Would it be possible to convert this drawing to a tree-phase machine? I tried but I couldn't do much...

Thanks!

This is to give you a start. The picture is a partial reproduction of a picture found here. The IMHO only somewhat subtle point is the clip at the beginning because one has to dial an appropriate orientation.

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{arrows.meta,bending,decorations.pathreplacing}
\begin{document}
\begin{tikzpicture}[font=\sffamily,very thick,sc/.style={circle,draw,inner sep=1.5pt}]
 \begin{scope}
  \clip (4,0) arc(0:-360:4) (0,0) circle[radius=5cm];
  \fill[gray!50,even odd rule] circle[radius=5cm] circle[radius=4cm] 
   foreach \X in {1,...,6} {(\X*60:4) circle[radius=0.5cm]};
 \end{scope}
 \foreach \X [count=\Y starting from 0] in {A,B,C,A,B,C} { 
 \path(180-60*\Y:4) node[circle,draw] (n\Y) {\X};
 }
 \foreach \Y in {0,...,4}
 {\draw[dashed,-{Stealth[bend]}] (180-72*\Y-5:3)
    arc(180-72*\Y-5:180-72*\Y-67:3);}
 \fill[gray!70] circle[radius=1.8cm];   
 \foreach \X in {1,...,20}
 {\draw (\X*18:2) circle[radius=0.12cm];}
 \draw (n1) -- (120:5.8) coordinate (aux) -- (-6.7,0|-aux)  node[sc,left] (c1){};
 \draw (n3) -- (0:5.8) |- ([yshift=8mm]c1.east)  node[sc,left] (c3){};
 \draw (n5) -- (-120:5.8) -| ([yshift=-8mm,xshift=5mm]c1.east)  
 -- ++(-0.5,0)node[sc,left] (c5){};
 \draw[decorate,decoration={brace,mirror,raise=2pt}] (c3.north west) -- (c5.south west)
  node[midway,left=3pt,align=right]{3 Phase\\ input};
 \draw (n0) -| (-5.8,-5.8) node[sc,fill] {} -- ++ (-1,0)
  node[left,sc,label=left:Common] (Common){};
 \draw (n4) -- (-60:5.6) coordinate(aux) -- (aux|-Common) node[sc,fill]{};
 \draw (n2) -- (60:5.6) coordinate(aux) -- (aux-|6,0) |- (Common);
\end{tikzpicture}
\end{document}

  • Wow, I like the way you designed the black lines with black dots and arrows! – manooooh Jul 9 '19 at 3:45

    @manooooh Yes, it is a very deep black. ;-) – user121799 Jul 9 '19 at 3:49

After a few hours I was able to do something similar to what I wanted in the beginning. Thanks for the help. I relied on the example provided in the following link: Cross-section of an electric machine circuit

    \documentclass[tikz,border=20pt]{standalone}
