If I use ND magnets with a Br of over 1T, it is almost impossible to keep the thin parts of the field and armature core out of saturation, without making the field core and armature core very nearly as thick as the magnets are wide. This would make the motor extremely heavy. Is it "bad" to...
I am hoping someone here has experience with permanent magnets. Since I haven't been able to find any published techniques (that arent really expensive FEA sim programs) I have a theory on how to size a permanent magnet for an alternator I am designing, and I want someone to confirm that my...
I am trying to model a current mode dc/dc converter as shown by Dr Ray Ridley, which requires a block that has a double zero and no poles. (http://www.ridleyengineering.com/downloads/curr.pdf page 9)
The block is H=1+s/(wn*Q)+s^2/(wn^2) where wn and Q are constants and s is the laplace...
