Create rotating magnetic field ?
« on: May 19, 2015, 02:00:56 pm »
Hi. I know they usually create rotating magnetic field by 3 phase current ? But how to do it with 1 phase current ?

Make it DC and then generate multiple sinus signals with equal amplitude and period but differing phases.

Or place a magnet or coil on a turntable.

What do you want to use it for?
