Electro magnet design software advice?

[Honk]

Hi.

As most of you readers know I've been helping Jack to build a controller for his very promising Magnet Motor.

I have come pretty far in my own design of a Hilden Brand style motor but now I would like to simulate the flux fields
of the electro magnets within the motor. I could of course make test windings but this takes a lot of time.
I wonder if you guys can recommend a good program that can calculate the flux in electro magnets with a silicon steel core?
Once I have the motor and magnets calculations completed I will release my my stuff here at OU forum.

You will know of FEMM:

and I presume that it cannot do it. Why not ask
the boss if he will write up an implementation of
exactly what you need?

No harm in asking.

I have installed the FEMM software but I find it very difficult to use. Perhaps I'm stupid
but the interface is not very self tutorial. Just to form the desired shape is hard to do.
Isn't there just a simple spreadsheet where I can input the numbers and get the result.

If the input numbers would look somewhat like this it would be nice.

1 ) Square Area of Silicon Steel Core.
2 ) Length of Silicon Steel Core.
3 ) Outer radius of Silicon Steel Core = Inner radius of coil
4 ) Diameter of used wire.
5 ) Number of wire turns.
6 ) Number of wire layers.
7 ) Total wire resistance.
8 ) Output gauss of the electro magnet with steel core.

Hi Honk,

I had the very same experience when I first tried to use FEMM, until I downloaded the tutorial and worked through it, and then everything seemed fairly straight forward. Now I find it very quick to develope new models. Also invaluable is the Lua script facility, which allows to automate incrementing the rotor of a model a few degrees as desired and torque measurements or gif pics saved for every increment, all at lightening quick speed. I would recommend making the effort to learn the Lua scripting.

Thanks, where can I download the Lua scripting?
