The Vidar-magnet motor MK2

[Low-Q]

Can someone please tell me where the sticky point is, and maybe how to reduce it?
The rotating parts are iron, and the parts inside the outer stator magnets are also iron.

Hi,
very nice motor !

Can you please post the FEMM files in each position , so I can have a look at the calculated torque
output from the rotor ?

You can calculate the torque with FEMM over the whole cycle and then see, if there are
more positive torque components or if all torque components will
sum up to zero...
But this looks like there is always a positive torque or
at least most of the time !
That?s very good !

Regards, Stefan.

I haven't stored all positions, but I have used -10 degrees for each position. All lines in the rotating part is "curve". and the center position is 0, 0.

Idon't know how to measure torque.

Hi Vidar,

Nice animation!

I can't use femm quite well, but if i can recall correctly, you can measure torque by clicking on parts / blocks of your simulation, then click on the integrate button and choose torque from the list.

Here is 18 saved FEM-files, -10 degree for each file. I cannot find the integrate button (How does it look like?), not in the file menu...
