Electromagnetic railgun

[nishant]

I have decided to make an electromagnetic rail gun,in such a way that three of them are ligned with each other and connected centrally,my problem is that how do I make them rotate at a fixed speed.

you are not being clear , at all , on what you are trying to do..
do youn mean that you want to connect three together ' gatling gun ' style?

I would think you would need some kind of slip ring device that would allow the three to rotate while still having electrical connections in tact.
