Magnetic Equivalent Circuit (MEC) literature? 1

sjens · Jan 5, 2006

Hi,

I'm designing a magnetic spring, which will initially be designed using a MEC model (magnetic reluctance circuitry). Does anyone know any good books or papers about this subject? I found some literature, but the magnetic circuits are only briefly explained, and I need specific information for the permeances in my airgap.....

If you can neglect fringing flux, the permeance of an air gap is simply (area of gap)/(length of gap).

Moskowitz's book Permanent Magnet Design and Application Handbook has some good sections on permeance/reluctance calculations. It also acknowledges Rotor's book Electromagnetic Devices as a source.

Hope this helps,
Mike

Thanks for the tip! I already found the Roters book, which has already been very useful, and I'll check out the Moskovitch book soon.
The problem in my case is, that it's a tubular strucure, with loads of different circular paths, which all should be characterised well.
