Modeling transformer wounding

Modeling transformer wounding

Modeling transformer wounding

(OP)
I need to model wire wounding around circular core- doughnut with rectangular section. Something like shown in attached picture.
Is there a way to create rectangular helix that will be curved?

Thank you,
Boris

RE: Modeling transformer wounding

Winding.
The feature you seek is a sweep of the wire crossection over the path of the winding. The crossection is easy, a circle in the plane where the wire starts, the sweep is harder. You need to make a 3D path for the sweep to follow, offset from the surface of the toroid by 1/2 the wire diameter. Try it without the corner radius at first.

As SnowCrash stated, the 3D path  is harder to do and the resulting sweep will probably bring most computers to their knees!

Unless you have a very good reason that demands you model the actual windings, it would be better and easier to just make a solid revolve of the external dimensions. If you need a cross section for a manual illustration, then use a decal/bitmap texture on the cut face.

RE: Modeling transformer wounding

If you pattern the feature it should have a lot of CADing and might be lighter.  It might be worth having a small gap between the 2 parts.  Hope this helps.

Sorry cannot open file, I am still on SW 2008

RE: Modeling transformer wounding

I have faked it before by making 1 sweep around the part then doing a circular patern.  Then for the wires coming off to the bobbins I just did sweeps that blended into the wires wrapped around the toroid.  Technically not correct but it looked good enough for assembly drawings of both the torroid and the PCB it was put onto.
