Generators / ST generator theory of operation?

« on: January 24, 2007, 04:58:23 PM »

I'd like to learn more about how the ST type generators work. I wonder if someone could refer me to a resource describing the details of how this specific type of generator works.

I'm interested in learning the basics about how voltage regulation is done as well. I've read many of the discussion threads here about the problems with the simple voltage regulation found in many of the ST heads and the problems it causes with the waveform, but without understanding more about how the generator works I'm having difficulty understanding the problem with any depth.

I've read a number of articles about construction of 3 phase generators for wind turbines, but these have all been constructed with magnets. I don't yet have an ST generator to disassemble so I'm not quite sure what to look up.

Thanks!

Listeroid Engines / Obtaining listeroid 6/1?

« on: October 10, 2006, 05:33:42 PM »

Howdy all,

I'm a bit of a newbie here, so apologies for the simple question and frustration.

I'm trying to find someone to sell me a 6/1 listeroid some in the next couple of months, but it doesn't seem like anyone really wants to sell them. I emailed a couple of guys from the marketplace forum who advertised them and someone I was referred to by a reputable source, and no one replies to my requests for information (except the ones who aren't selling the engines anymore because of EPA regs).

Is listeroid ownership a of private club where I have to pretend to know what I'm doing before anybody will sell me one? Bad form to look like a newbie while trying to buy one? Magic words one has to invoke when requesting a quote?

Granted, I'm not standing here with cash in hand ready to buy, but I'm at least hoping someone who sells the engines (or 'spare parts wink wink nudge nudge') might at least give me a ballpark price and tell me if I need to make any special provisions for getting the thing off the truck and into the garage when it arrives. I like to prepare and know what I'm getting into before I drop a substantial amount of cash on something, so the silence is frustrating.

Is it common to have difficulty finding someone who sells these things? Have the EPA regs killed the domestic listeroid market already?

Thanks for any advice.

Lister Based Generators / Listeroid backup generator questions

« on: September 28, 2006, 05:25:34 AM »

I am planning to buy a 6/1 listeroid for backup power generation. I have a few questions about how to set it up.

First, is it a bad idea to use a genhead that is oversized for the engine? I'd like to be able to use the genhead with another larger engine. I could save some money if I can use the larger (15Kw) ST generator on the 6/1 listeroid.

Second, when the generator is running the house, how important is it to have the load balanced between the two 110v branches? If the loads are severely unbalanced what is the consequence?

Third, if I'm running a large enough generator, can I attach a second listeroid (maybe a 12/1) to it and share the load between the two engines? Would it be better to set up the second engine to drive an induction motor to sync it to the first motor?

Thanks!

Engines / Lubrication with veg oil?

« on: September 26, 2006, 02:13:08 AM »

Greetings all,

I'm planning to buy a lister-type engine, initially for backup power for an on-grid home and eventually for service as the primary generator for an off-grid home. Part of my goal in living off-grid is to be as self-sufficent as possible (or at least to demonstrate to myself the capacity to be) and so I'm planning to experiment with using exclusively home-grown seed oils for fuel. If this works out I'm left with supplying an appropriate oil for lubrication of the engine.

The obvious question follows, is there an oil I can produce myself (in the midwest of the USA) that could serve in place of motor oil for lubricating the lister?

Thanks for the advice. I've just started reading about these engines in the past few weeks, and have yet to get my hands on one, so apologies if my question seems silly.
