Whip-Mag Simulator
« on: April 21, 2009, 10:20:34 PM »
I was trying to understand how it would be possible to have magnetic attraction / repulsion be greater in on direction than the other by shifting magnets around as suggested in the Whip-Mag Motor.  To help my understanding I made this simulator to better understand what was happening.

If people could let me know what data has worked, I can update this demo accordingly.

http://rapidshare.com/files/224125344/Flyboys_Whip-Mag_Simulator_01.gif

Data:
Simulator used: Vizmag version 3.182
Stator Magnet: (round)
-Permeability = 1.100
Strength = 50.000 Tesla
Dimensions = 10.00 X 15.00 X 10.00 mm
Radius to Center of Magnet: 170 mm

Rotor Magnet:(square)
-Permeability = 1.100
Strength = 50.000 Tesla
Dimensions = 10.00 X 30.00 X 10.00 mm
Radius to Center of Magnet: 150 mm

Stator and Rotor Magnets are parrallel to each other with an offset of: 0 degrees

I don't know how to calculate force on this simulation.  I can easily calculate total force on the stator at any given moment, but am confused when forces cause rotation of the stator as well.

This simuator looks to be the cats meow... Posted by Jdo300.  Wish I had found FEMM prior to spending the time to learn vizimag.

Ur WhiPmag simulation is excellent my friend.
Well done. ( Tho i prefer mine Rare if at all possible!!)

Indeed torque can not be calculated with vizimag. If there was a couple of forces causing torque it would indicate 0 N force because it looks at the net force not what torque these forces cause.

thanks for the comments guys,
Broli, you are correct in saying vizimag is limited to total force at a moment in time.  I am needing to come up with a way to Calculate all the forces and then take multiple readings throughout the cycle and add them together to get the NET amount of force... unfortunately I am in the dark as how exactly to do that :).  I'm hoping others will jump in with a how-to  ;)

Does anyone know of a better simulator to use that is geared to calculating forces, not just flux.

The most comprehensive simulation I know of so far is the one done by korkskrew over on the fizzx.com forum. He used a combination of Femm, Excel, and Javascript.

Here's a link to the main discussion about the sim. You might find additional information if you search for posts from korkskrew:
