Magnetos Explained

[@PacoOtis]

Howdy, thanks for the video as you are an excellent instructor and educator. As a septuagenarian this video really brings back memories of south Missouri and the very old tractors and stationary engines and such. Getting a "spark" was often a big deal to those guys. Thanks again!

Best video of a magneto I ever saw !

[@tekknow8482]

Thanks for the info and the explanation. Very educational. Sometimes older technology is better than newer technology.

Thank you Pete. Clearly explained. Actually, the 'magneto' (aka magneto electrical machine) simply refers to the field of a permanent magnet moving across the conductor of a wound coil thus producing an AC waveform. The magneto was invented by the Frenchman Hippolytus Pixii in 1832 - some 70 years earlier. As a low voltage generator, the magneto was quickly superceded by the dynamo. Robert Bosch's pre-WW1 patents (British and US) refer to 'magneto ignition'. He doesn't claim to have invented this as his patents refer to 'improvements in magneto electrical systems' only and relate to coils, contact breakers and secondary coils. Like many discoveries in the late 19th and early 20th centuries, there's no one single inventor, just a series of steps and breakthroughs on the journey to current tech. The telegraph, telephone, electrical transformer, wireless are all examples where there is only one inventor in popular folklore but many inventors in historical reality.

Absolutely terrific video! As a model engine builder, I've read a lot about old magnetos. But, seeing one apart really helps clear up their construction. Clever repair by the way... it seems one could turn a replacement commutator from modern materials if you had to.

Great explanation video. I 'm looking forward restorating the M01 on my BSA M20. Still waiting for your video regarding the generator.

"I heated everything up in the oven at 200 Deg .. for about 20 minutes just to drive off any moisture which might be present.. Good idea when baking magneto, generators or crank shaft assemblies or whatever in the oven is to make sure your wife isn't home" magic moments at 10:16

Great vid Pete. Very informative and I enjoyed it!

[@AK-ck7cy]

I wish you had shown how to put the new condenser in. And how you connected it up. I have a AB 33 magneto it's pretty much the same. I just wanted to see how the condenser was conecteted in. Any way it's a great video.

Hi Pete, Would you know the capacitance value of the solid state capacitor used here? I have been working on few old magnetos with bad condensers, and I am looking to replace it with a modern day capacitor.

[@Ziknazoo]

Oh. One more thing. I'd love to see more videos!

[@deeds3611]

Thanks Mr Gagan - very helpful. Cheers

My mom did not go for this either, I told her if she wanted that lawn mowed, the mower would have to be running, or pay a nice was for a new coil, it was all up to her.

Very good but is the mag on a bike the same as on a plane.

[@tekknow8482]

Do you happen to have any information on a magneto containing a "shield"?

[@robwahl]

Very helpful, thanks

[@dancosmin4598]

great video, sound is shit (mono) can you please fix that

[@brandonquenneville7330]

old man voice wow* I sure hope I sound like this one day

[@lukegrainger8670]

no sound

[@spnjohansson]

thank you

[@canitogalicia]

Thank you Sr. For teaching the new millennium ignorant kids how things work....

[@sabarinath6962]

good...

[@69adrummer]

There ain't no damn sound!! fix and re-post

[@robertbrandywine]

There is sound for me.

[@bdrichardson403]

I got sound w/ no problem at all. Enjoyed the vid. Thanks for posting.
