![Orthocyclic coils are characterised by a high copper fill factor (often approx. 70%), so that a comparatively high magnetic field is realised in the smallest possible space.](https://25463740.fs1.hubspotusercontent-eu1.net/hub/25463740/hubfs/03_blog/Manufacturing%20partner/Orthocyclic%20coils_Combo_900x430.jpg?width=900&height=430&name=Orthocyclic%20coils_Combo_900x430.jpg)
ADVANTAGE OF ORTHOCYCLIC WOUND COILS
Orthocyclic windings allow the ‘densest possible stacking’ of turns. A transverse section of an orthocyclic coil would have a honeycomb shape. Orthocyclic coils are characterised by a high copper fill factor (often approx. 70%), so that a comparatively high magnetic field is realised in the smallest possible space.
![Edgewise winding is one of the modern trends in coil manufacturing. The principle of this winding technology is that the rectangular section wire is wound not on the short side, but on the flat part of the wire. That’s what the terms edgewise winding or side-winding stands for.](https://25463740.fs1.hubspotusercontent-eu1.net/hub/25463740/hubfs/03_blog/Manufacturing%20partner/Edgewise%20coil%20900x438.jpg?width=900&height=438&name=Edgewise%20coil%20900x438.jpg)
