I am trying to calculate the power required and resulting force for a linear motor, but I have been unsuccessful in finding the necessary equations.
You have the youtube link? Otherwise, most engineers will associate the term with a 3 phase device.A tube with wire-wrapping to generate the magnetic fields which act on a magnetized cylinder. I would like to move the cylinder through the magnetized tube.
You'll hardly find exact equations for something like that. Maybe, there are some aproximative formulae based on numerical simul, but I don't remember if I ever saw them. Sorry :(Something like this:
I am specifically looking at the part where the brass rod is moving.
Are there details of the construction? It appears that the brass tube houses 16 concealed magnets. That (upside-down so we can't see) circuit board houses his electronic circuitry. The two wires going to the coils may be multistrand, so actually 4 or more separate phases/wires.A tube with wire-wrapping to generate the magnetic fields which act on a magnetized cylinder.
