Stator ring coil and connection questions

Click For Summary

Discussion Overview

The discussion revolves around the design and powering of a steel stator ring with multiple coils, specifically focusing on the number of windings required to achieve a desired magnetic field strength of approximately 1.3T. Participants explore the feasibility of using AC versus DC power sources and the implications for coil configuration and connections.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant, Stephen, inquires about the appropriate formula for calculating the number of windings needed per coil on a 6-coil stator ring powered by 3-phase AC, suggesting the use of the solenoid formula B=mu*N*L.
  • Stephen questions whether a standard AC plug with one hot leg and one neutral can be used to power the coils and how to connect them to create a rotating magnetic field.
  • Another participant asserts that using a standard outlet for 3-phase AC is not feasible and advises Stephen to learn more about single-phase motors and 3-phase power generation fundamentals.
  • Stephen later asks if it would be possible to use 4 coils instead of 6 with the same AC outlet and whether DC would be a better option, seeking guidance on coil configuration (delta or star) and connection methods.
  • A later reply states that DC will not create a rotating magnetic field, only an electro-magnet, implying limitations of DC in this context.

Areas of Agreement / Disagreement

Participants express disagreement regarding the feasibility of using standard AC outlets for creating a rotating magnetic field and the effectiveness of DC power for this purpose. The discussion remains unresolved on the optimal approach for powering the coils and the necessary configurations.

Contextual Notes

There are unresolved assumptions regarding the definitions of terms like "rotating magnetic field" and the specific requirements for coil configurations. The discussion does not clarify the mathematical steps needed to determine the number of turns per coil based on the desired magnetic field strength.

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