Discussion Overview

The discussion revolves around the construction of an alternator for a science project, specifically focusing on generating AC power while controlling voltage and frequency. Participants explore feasibility, safety considerations, and potential methods for achieving the desired outcomes.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant expresses uncertainty about the appropriateness of the forum subsection for their project on generating AC power.
  • Another participant suggests browsing a specific forum section for similar questions.
  • There is a query about the feasibility of building an alternator capable of creating arcs.
  • A response indicates that a high voltage transformer is necessary for creating arcs and questions whether the project involves a "Jacob's Ladder."
  • One participant explains that frequency can be controlled by the generator's speed and voltage by the winding ratio of a transformer.
  • A suggestion is made to use a neon sign transformer for generating arcs while emphasizing safety and the use of a voltmeter for instrumentation.
  • Another participant cautions against high voltage for a science project, noting that it is typically reserved for specialists.
  • A participant thanks another for their advice regarding high voltage safety.
  • One participant mentions reading Tesla's writings and wonders about applying similar concepts to their project.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and safety of using high voltage in a science project, with some advocating for caution and others exploring the potential for creating arcs.

Contextual Notes

There are limitations regarding the assumptions about safety and the technical requirements for generating high voltage, as well as the specific applications of the discussed technologies.

not exactly sure if this is the right subsection

I need to make something that generates AC power (an alternator) for a science project. The reason for this is that I need to control the voltage and the frequency. Is there anything in particular that I need to know?

Can I call you y?
 


Would it be feasible for me to build one that's capable of creating arcs?

You need a high voltage transformer for that. You can't, generally speaking, make an alternator that puts out that high of a voltage.

Are you making a "Jacob's Ladder"?

good one!

The frequency would be controlled by the speed (rpm) of the generator and the voltage from the generator can be controlled by the winding ratio of a transformer connected to it.

If you want to create an arc that demonstrate you are generating power, then you could a neon sign transformer (7000 to 9000 volt secondary with a 110 volt primary) connected to a "Jacob's Ladder" as zoobyshoe mentioned. But I would suggest using a voltmeter connected directly to your generator. If your project is for a science project, you need to be safe and the voltmeter shows you know a little about instrumentation.

How are you planning to turning your generator? Maybe a hand crank?

unless you can make do with something like an electrostatic flame starter that you purchase off the shelf, high voltage is probably not appropriate for a science project. they wouldn't even let us use HV in electrical engineering senior design projects. it's something best left to those who specialize in it.

Thanks Photon Soup. That's the best advice.

Thanks for all the replies.

I was reading some of Tesla's writings and wondered if I could do something similar.
