Designing a DC-Excited E-Core Magnetic: Calculating Characteristics

[Tmaczorro2]

Hi, I would like to calculate the characterics of a magnetic that is excited by a direct current[dc] source. I aim to use a E-core for my design.

What kind of characteristics and what kind of core material?

Hi, I would like to calculate the characterics of a magnetic core that is excited by a direct current[dc] source. These characterics are winding wire area[diameter], Current desity, window utilization factor ku, current in the wire. I aim to use a E-core for my design.

Other than ku, none of the characteristics you mentioned affect the core. What you probably mean is you want to find the flux density in the core for a particular dc current or peak current. Is that correct. You probably also want to find out the inductance and the number ofturns that will give that particular inductance.

The wire sizes will depend on how much is the dc current level and hence current density J can be calc'd.

Electromagnetics simulation tool

Infolytica offers a free version of their MagNet tool at http://www.infolytica.com/en/products/trial/. I tinkered with it a bit over the holidays, and I think it will easily do what you are after. They've also got some great documentation at http://www.infolytica.com/en/products/trial/trialdoc.html. Start with the Year 1 Electromechanics PDF. It is really quite good.
