Inductive open core current limiter (Educational model)

thingiverse

For one of my master courses in Electrical Engineering, I had to analyze the magnetic flux in an open-core current limiter*. Since I struggled to grasp the physical events unfolding, I decided to create a model and print it so I could hold something tangible to visualize everything more effectively. As this was solely for personal use, I chose not to print the bottom of the windings, but included them if you'd like to include them in your print. Please note that the model is a 1:1 scale, as I printed it at 50%. To ensure a successful first-time print (which I achieved!), tolerances are on the higher side. This may result in pieces that can be somewhat loose. *D Cvoric et al., 3D nonlinear transient field-circuit modeling of inductive fault current limiters, 2015
