Hello,
I am working on induction heating cookers. I need to model the coil using litz. so is there a example or documentation that i can use to make the coil. I am attaching the coil type that i have to model.
thank you
Hi,
Unfortunately we don’t have any example about coil using Litz wire. But if you want to take into account of the proximity effect you can use coil conductor region with loss. This region is available only in steady state AC magnetic.
Best regards
Hi, I am also working with induction cooktops.
Could you help me with some models? I aslo want to model that kind of coil.
Hi there,
There are two reliable approaches I've found for modeling litz wire, depending on your simulation needs:
1. Simplified Method (2D Steady-State AC Magnetic – XY or Axisymmetric)This is the more straightforward option. In this case, you define the litz wire’s cross-section as a coil conductor region and assign its electrical characteristics using the Coil Loss Models menu. While limited to 2D steady-state AC magnetic solvers, it’s effective for many typical use cases.
2. Detailed Method (2D/3D Steady-State AC Magnetic)This approach is more detailed but offers broader applicability, including full 3D simulations. You model the litz wire coil as a solid volume (e.g., a tube-like shape) and then apply the resistance value provided by the manufacturer. You’ll need to request this resistance specification from the supplier directly, as it’s based on their internal design.
As a reference, I’ve attached an excellent document from New England Wire Technologies, which provides a trustworthy method for estimating litz wire resistance. It may serve as a helpful guide when applying this method.
Hope this comment helps!
