1931 A More Powerful And More Efficient Generator And How To Build It

I'm a 50 year old electrician and I love your channel. I'm learning so much 😊 Thank you

I can't begin to tell you how happy I am to have found your channel Mr. Smith. You're a modern day Mr. Wizard providing conceptual physics & engineering lessons in practical applications~

Consider creating IKEA level drawn instructions on how to create these. And all your models and innovations.

What I love most about the serpentine coil is how easy it is to make. Even if it were less efficient, it would still be a huge upside that a child can build them.

Mr. Murray-Smith, what a fabulous resource you are for ideas and things to ponder and consider. And it's tons of fun watching you and seeing your enthusiasm! Keep up the great thinking and tinkering!!! The world could use more people like you!!! God bless you, sir!

This is basically what I have been working on and commented on an older video. A little longer coil and stronger magnets. So cool to see you doing the same thing and bathe same time basically. Keep up the great work!!!

When you get this all worked out CAn you make detailed laymans instructions on building it. Love your stuff Keep up the good work!

I suggest (again) inserting a steel cylinder inside the rotor. This will magnetically connect the N/S back ends of the magnets, strengthening the magnetic field intersecting your serpentine coil. You will have to apply more torque but will get higher voltage out, which makes the generator even more effective for its size.

Once you have the design, protopasta makes an 80% iron infused PLA that has a permeability of 5-8. Making the stator and cover out of that would further improve the flux change the windings would see.

This an absolutely brilliant video, This also makes an most excellent motor when ran (can use hall effect sensors or reed switches ) as such. A man named John Bedini designed a motor called a "window' motor , and i made several of them and realized they make excellent alternators, when ran as such. There is no cogging , which is nice , and its easy to get good current out at low rpms.... The serpentine coil makes it all so much easier.

​Robert you have inspired me to make ​these coils, though I have taken it a step further . I own punch presses and do tool and die work. I have built tooling which will form right angle serpentine coils out of 1/4" or 3/8" solid thick copper. No wrapping of single strands. The die is a progressive die set and the serpentine is taken up on a larger computerized machine coil, normally used for metal stamping of parts. Can cut to length making the diameter nearly any size wanted. Willing to supply samples for anyone interested. Keep up the good work.

This is why you pass information down from one generation to the next and this is why its a good idea to actually engage in historical research and history instead of neglect it and pass it off as outdated, you will not imagine the amount of stuff we have lost due to ignorance, This is something that would better our future use of better more effective motor generation

I'm actually working on an incredibly similar mechanism myself, glad to see a three phase serpentine coil works just fine👍

I am just amazed that his design has not been used way sooner Robert. Know for sure that now a many people will make the same method to make wind energy machines. Depending on location, this would make one self-sufficient and not care about cost of energy. Especially since electricity today is just going through the roof on ones electric bill. Nice work Sir. Peace vf

Very cool. I am looking at small, pedal-powered generators for a pedal car project. I know using a generator and motors will be far less efficient than a chain drive. This ought to help me save some of that efficiency. Thanks!

Thanks. I imagine generators are a bottleneck for many alternative energy projects, so it's splendid to have one that folks can build themselves.

A great simplification of a very complex topic. I'd like to see a video on low RPM generators - would it be possible to get more than a couple of watts out of a DIY low rpm (100-600rpm) gen by using larger magnets, bigger stator cores etc (with no gearbox required) or is it always preferable to use higher RPM in an AC gen? Keep up the quality stuff !

Great idea :) 3:05 if you make 3 coils to install them in 3-phase configuration, you would be increasing the horizontal length, which we avoided with the serpentine coils 😅

Instead of an outer sleave you should have another cylinder of magnets. Gauss rating is at the surface of the magnet. The further away the copper from the surface of the magnet the greater loss of gauss. To combat this you need to force the field lines of the magnets to travel to another magnet. This will improve efficiency by creating a magnetic circuit. Double the magnets for two rotors and one stator.

Great work Rob! Im currently following this series and trying to replicate (as best as possible) your designs with PVC fittings 😁👍 If i get something out of it ill share a video. Thanks for the inspiration ✌️
