Linear Synchronous Motor velocity?

[MeMark]

I have been studying Linear Synchronous Motor (LSM) technology recently and there is one thing that has me boggled.

I read that the velocity of anything using LSM depends on the frequency of the current being applied to the coils. The equation I have seen is-

v = 2fLw where "f" is the frequency and "Lw" is the length of the winding turns of the stator

So I get frequency, which I assume to mean 60Hz for standard US power from the grid. But I don't understand what it means by "length of winding turns".

I have read pretty much every online resource I could find regarding LSM, but I have not found anything that points out exactly what a "winding" is. Does it take into account the width of the wire? Spacing in between loops of the wire? Length of the loop? If anyone can point me in the right direction I would be very happy.

Use the references at the bottom of that article. I think spacing between loops is probably what it meant. To be sure, you must provide a link to where you saw 2fLw.
