# Stator ring coil and connection questions

Hello everyone:

I am trying to find a program or formula that will help me figure out how many windings, turns of coil, are needed per coil on a 6 coil steel stator ring powered by 3-phase AC power to get a certain magnetic field strength, about 1.3T. Is there any way that you could help me find out how many windings are needed per coil? Would I use the standard solenoid formula B=mu*N*L?

Could I use a standard ac plug with one hot leg and one neutral to power my steel stator ring coils, 6 total, to create a rotating magnetic field? If so, how would I connect the coils together and how would I connect those interconnections to the one hot leg and one neutral leg? And how would this affect the number of turns needed for each coil? Which would be better, Using a DC power supply or AC power from a plug with one hot leg and one neutral leg?
If DC is better to create the rotating magnetic field, how would I connect the six coils together and how would I connect those interconnections to a DC power supply

Thanks so much for the help.
Stephen

No, that will not work.
Before you start blowing breakers, I would suggest that you learn more about single phase motors and read up on fundamentals of 3 phase power generation.
There is no way to connect your standard outlet to create 3 phase AC.

no no... I was wondering if I could use the outlet AC plug with one hot and one neutral leg to connect maybe 4 total coils of the steel stator ring instead of the six coils for three-phase AC power. Can I do that? Or would using DC be better? If so, how would you connect the coils together, a delta or star, and how would you connect the coils to a DC power supply to get a rotating magnetic field?

Also, is there a way to figure out how many turns per coil is needed on the steel stator ring with 4-6 coils to create a rotating magnetic field of a certain strength, about 1.3T? Would using DC or AC as a power source change the number of turns needed?

Thanks.

DC will not work; there will not be a rotating field, only an electro-magnet.
