Flynn Motor Replication 4 - experimental version

Feb 4, 2012
I built this version so that i could change the configuration of the motor relatively easily. I also had a couple of other issues with the original motors - I have used relatively small magnets in relation to the armature size for a few reasons - one of them being that i was worried that saturation had an effect to play and so i wanted some degree left in the laminations before they were fully saturated, another was a sneaking suspicion i have that magnetic field strength would have some role to play in energy consumption as it relates to the power required to switch. Both seemed reasonable to me so i reduced the magnetic strength somewhat to see what effect it has - I don't have a gauss meter - so it is a little ad hoc. The magnets arent fixed by more than their own pull so it will be an easy - well relatively easy - job to pull the magnets and replace them with ones of higher or lower gauss. Yet another variable to play with.
