Animated eddy current densities in the stranded winding of an electrical machines. Rarely seen in public – read the post for more details!
Faster Analysis of Eddy-Current Problems: Impulse Response Method
Eddy current problems are usually linear and time-invariant. Thus, they can be fully modelled with their impulse response function.
How to Mesh a Stranded Winding
A stranded winding can be analysed with FEM, but it has to be meshed first. Here’s how to pack conductors in a slot for a good-quality mesh.
Why Equivalent Circuits for Electrical Machines Work
Equivalent circuits for electrical machines do yield correct torque estimates. They use the Lorentz force, but not in a way you’d expect.
Toroidion Patent – First Glance
The patent application by the Finnish supercar company Toroidion just became public. Here’s a first glance on what’s so revolutionary.
Incredible Power: Interview with an RC-Hobbyist
Radio-controlled helicopters are cool. Even more cool are the electric motors in them, with their insane power densities. I interviewed a proud hobbyist.
Power Armor – How to Build One
Power armors are AWESOME. Iron man wears them, Spartans wear them, Astartes will wear them in the near future. Here are some thoughts about tech.
How to Digitalize Healthcare
Digital stuff is in. Digitalized healthcare even more so. Hence, here’s my idea about how to make your visit to the doctor slightly less painful.
Time-stepping versus time-harmonic analysis
Good afternoon people, I hope you had a great Juhannus. Don’t celebrate it? Start next year. It’s awesome. But to the point: I’ve written on several occasions about time-harmonic analysis, mainly in the context of finite elements (FEM). See for…
Reluctance networks 104: Practical implications
Welcome back to my post series about reluctance network analysis. I started it after the acceptance of my paper to the EPNC conference, after which we have discussed some typical mistakes, and seen what to do instead. Today’s post brings…
