Hi,
For a demonstration I'm giving on how to turn rotary motion into AC signals I need some small AC generators (a few volts at a few mA). I'm really struggling to find anything suitable, has anyone here got any ideas? Car alternators, which are the smallest I can find so far, would be much to heavy for my drive source. (And since I'm not getting paid for this they must be cheap!) Thanks, Andy ------------------------- Andy Millar CEng MIET MCMI http://www.linkedin.com/in/millarandy |

Maplin do some self build motor kits as educational toys for about a tenner. Might be possiable to adapt one?

I hadn't come across those before, thanks. Thinking about it, it would probably be easiest if I had the magnets on the rotor and the coils on the stator, might be possible to rebuild these like this.
Still open to ideas for ready made alternatives! I have just remembered that bicycle "dynamos" are actually alternators, they might be a possibility. (Posted simultaneously with Alan's reply! Thanks Alan.) ------------------------- Andy Millar CEng MIET MCMI http://www.linkedin.com/in/millarandy Edited: 11 October 2010 at 09:13 AM by amillar |

Electric model aircraft use small 3 phase motors and inverters (and get 750W from something the size of a coffee cup).
http://www.puffinmodels.com/category.php?dept=189 These may serve as small alternators. Best regards Roger |

If you can find an old cassette recorder, video or record deck (showing my age) Some of them had small AC motors.
An AC fan may work. Best Regards Nick |

I think the problem with these is (I am sure that someone will correct me if I'm wrong!) that they are actually universal machines, so although they run on AC or DC they will only generate DC? Or nothing? It's been a scarily long time since my motors lectures, I've been spending too long with namby-pamby bits of silicon.
Anyway, at the moment I'm looking at a plan B, using fixed magnets on my rotors with old relay coils as the stators. ------------------------- Andy Millar CEng MIET MCMI http://www.linkedin.com/in/millarandy |
