Hi Gert
and the rest of the group. I amnew
to this myself, but as far as I know there are three ways to increase the force
from your solenoid. 1)
increase the current density 2) Improve
the coupling of the magnetic field to the armature 3) improve
the materials. I know
little about materials so can't help there. You may be
able to improve the coupling by adding iron/steel to focus the field onto the
armature (is that the right word?).
Steel is an easier route for a magnetic field than air is, so you can
use it to direct the field where you want it. One of the most effective improvements is to add end plates
to the solenoid. Increasing
the current density will work against your need to reduce heat. You can increase the current density by
increasing the diameter of the wire.
I am sending under separate cover a spreadsheet I use. I hope
this helps Adrian --- In
