Talk:Magneto

message: What /sucks/ is the clutter about contact points? I've never seen contacts on a magneto although I hear motorcycles have them and I suppose they are common enough. Typically it's even more fault tolerant due to the absence of moving parts aside from the flywheel bearing (which isn't really part of the magneto). The coil placement defines the firing window and is sometimes adjustable on the fixed gap & I've seen fixed timing with an adjustable gap. The former is ideal, but I came here looking for the effects of the gap adjustment... The article seems to imply points are necessary and I feel like points are more of a refinement. The most basic magneto drives the coil directly as the magnets sweep past.   
I suppose the flywheel is technically a moving part but it doesn't wear due to any association with the nearby coil.
:Then you've never taken a magneto apart.  All magnetos on engines have a contact breaker (points).  It is possible these days that some bright spark (!) has devised a way to operate them electronically, but without a constant source of power, it is difficult to se how. 86.184.24.140 (talk) 12:50, 17 June 2011 (UTC)

message: I restored the single-line disambiguation header to the page.  I think this reads better, and it's more in keeping with the form at Cream, which is explicitly referenced in Wikipedia:Disambiguation.  This seems to be the standard, and I think it's desirable to keep the header as vertically short as possible.  If we end up adding yet another meaning, then we should probably created Magneto (disambiguation) - but for only two secondary meanings I don't think we're there yet. -mhr 23:27, 12 Jan 2004 (UTC)

message: I'm moving this sentence to the talk page:
:Most importantly, the magneto does not have the ability to start the rotation of the engine or of itself, so that an alternative starting method will be required for a machine using a magneto. Some such methods are the starter motor, kickstart, starting crank or pull cord, starting charge, or the like.
This statement is somewhat misleading in that it implies that only engines with magnetoes require separate starters.  All reciprocating internal combustion engines need an external starting method, regardless of ignition type. Nibios 21:10, 11 July 2007 (UTC)

message: I don't have a source so I'm not putting this in, but the wheel mounted generator used power the headlight on a bicycle is a magneto, although it is incorrectly called a dynamo in common usage. Rees11 (talk) 16:14, 11 April 2010 (UTC)
replies: text: Yes, good point. The Sturmey-Archer Dynohub hub dynamo which I lovingly installed on my pushbike in the 1960s, for example. Andrewa (talk) 18:25, 2 July 2011 (UTC)

text: I have done a little work on the article linking to other places where this material is already in Wikipedia. It doesn't seem a good time to do too much work on the article, though, see below! Andrewa (talk) 19:02, 2 July 2011 (UTC)

message: It has been suggested that this page or section be merged with magneto (generator). Both aricles seem to have the same referent and scope.  Chrisrus (talk) 03:41, 6 June 2012 (UTC)

message: A Request for Comments is in progress at Magneto (generator) concerning whether to merge that article with this article, rename that article to Magneto (bulk power generator), or do neither and leave the article alone.  Discussion should be there, using the RFC process.  Robert McClenon (talk) 02:16, 2 April 2015 (UTC)

message: I'd post this on the talk page of Ignition magneto but the bear pit of splitting/combining has frozen the latter in a way I don't actually support.  I challenge the Ignition magneto 'Operation' claim that the HV voltage is at all dependent upon the primary/secondary turns ratio.  Magnetos are not transformers.  It is a function of the rate of change of magnetic flux, and the secondary turns.  When the flux collapses, the only limitation is the arc-gap at the contacts of the primary + capacitor.
