Torque Calculation for Magnetic Coupling

Torque Calculation for Magnetic Coupling

Torque Calculation for Magnetic Coupling

Hello Everyone:
I have read some articles on magnetism but I am still new to it.
I am looking to construct a magnetic coupling with N40SH magnets. What if Two cylindrical shaped magnets with each having 6 sections (same size and shape) of N40SH Magnets with N-S-N configuration (See Attached Pictures).

I did some research, read some articles and found that it works, but I need to get the calculations done so instead of manufacturing every time new things we simulate and then we validate what suits us best. Any method of calculating the max torque would be really helpful??

RE: Torque Calculation for Magnetic Coupling

The picture shows 8 sections but I am going to use 6 so please consider that 6 for now.

RE: Torque Calculation for Magnetic Coupling

I found Ampere 3D software work well. It is a standard torque calculation

RE: Torque Calculation for Magnetic Coupling

If you are making a product for sale, you should do a Patent search first. There are a lot of Patents for magnetic couplings.

MagBen: thanks for your quick response. Unfortunately, I don't have that software. I checked online to see if I can download a free trial version but couldn't find anything.
do you know any equations or link that shows somewhat similar calculations??

RE: Torque Calculation for Magnetic Coupling

FEMM is strictly 2D, I don't think it can do that calculation. Perhaps it could be done with Radia?
