PART 17 DUAL PERMANENT MAGNET ROTOR AXIAL FLUX WIND TURBINE DESCRIPTION: IN THIS VIDEO, WE MAKE THE MAGNET ROTOR TEMPLATE FOR PLACING MAGNETS ON THE ROTOR. THEN WE TAP THE HUB AND DRILL THE JACKING BOLT HOLES AND TAP THEM. AND SHOW THE HUB , SPINDAL, AND BEARING SET UP. AND DISCUSS A FEW THINGS ABOUT KEEPING BALLANCE THROUGHOUT THE UNIT. AND WE SHOW HOW TO TAP THE HOLES THE RIGHT WAY, ALSO WE DISCUSS THE REASON FOR USIN A 27/64ths INCH DRILL BIT SO THE INNER DIAMETER OF THE THREADS IS NOT LOST. IF WE USED A 1/2 INCH DRILL BIT, THERE WOULD BE NO THREADS TO MAKE. THANKS! MUDDy
@GREENPOWERSCIENCE YA I KNOW. THE MAGNETS ARE LIKE INVESTING IN GOLD OR SILVER.
THANKS A BUNCH FOR THE COMMENT. SAY HELLO TO THE BETTER HALF.
I GOTTA GET THE MOTOR CYCLE RUNNIN SO I CAN GET SOME OF THAT SOLAR FUDGE.

EXCELLENT VIDEOS MUDDy
Magnet prices have 3x in the last 6 months. Crazy. Those mags are now $23 each.
Keep up the EXCELLENT WORK!
@DIYMakerman LOL.

@muddymuddymuddmann Luckily for us, old buddy, they find us both.
@betocarrera1 COMMON COPPER,. THE MAIN THING ABOUT MAKING THE MAGNETIC FLUX WORK FOR YOU … IS TO GET THE MAGNETIC FLUX TO GO THROUGH THE COIL. THAT IS THE JOB OF THE IRON CORE OR FERRITE CORE.. ON AN AXIAL FLUX DESIGN, IT IS NOT NEEDED. THE MAGNETIC FLUX TRAVELS DIRRECTLY BETWEEN THE 2 MAGNETS FROM BOTH ROTORS. ALL OF THE FLUX GETS USED FOR POWER IN THE WIRES, AND NOT IN THE CORE. MUCH MORE EFFICIENT.

@DIYMakerman IF THE WOMEN DONT FIND YOU HANSOM, AT LEAST THEY’LL FIND YOU HANDY. LOL.

@FlyinBrian777 I USED TO DO THAT ON MY DREMEL. IT WORKED JUST FINE, BUT I USED A SEWING MACHINE FOOT PEDAL. SMOOTH OPERATION. AND IT CAN HANDLE THE CURRENT. I THOUGHT OF USIG IT ON THE SAWZ ALL, BUT I DIDNT HAVE THE TIME TO LOOK FOR IT. I FIGURED LOW SPEED WAS JUST FINE FOR NOW. I HAVE ANOTHER TABLE SAW THAT THE MOTOR IS BLOWN ON. I AM THINKING OF MAKING IT INTO THE SAWZ ALL TABLE.

Hi Scott, thanks for the explanation.If you do not mind,I have 2 more question.
The wire is a comun copper?I always learned that a electric magnet need a iron or a ferrite inside the coil …..i saw there is nothing inside the coil.Is the wire special.
I am glad you liked the motor.I work making molds for plastic injection ,and also do injections.If there is any thing you need on this area ,let me know.
The stator came out real good.congratulation.Tchau.Beto.
@muddymuddymuddmann Ya know, old buddy, your story sounds a little like a Red Green episode. 🙂
Muddy, just an idea… can you lock your sawzall power button down and then just put a dimmer switch in-line? Finer rpm control I’m thinking, but what you’re doing works! Maybe I’m a nit-picker 😀
Keep up the good work, I’ve been following this series closely.
@DIYMakerman YUP IT MUST HAVE LOOKED COOL TO SOMEONE. THAT’S THE PITS. I HAD A MOPED THAT GOT STOLEN 3 TIMES IN VIRGINIA. EVERY TIME SOMEONE ASKED ME IF I WANTED TO SELL IT. SO THE LAST TIME SOMEONE ASKED, I SAID NO. I WENT TO THE AMMACO STATION WHERE THEY SOLD RACING FUEL, I MIXED JUST A SMALL AMOUNT OF OIL TO COLOR IT A BIT. AND STUCK MOTH BALLS IN IT. I LEFT THE CAN CLOSE TO THE ROAD. YUP! 5 MOPEDS BIT THE DUST. AND I RAN A 120 WIRE TO MINE. SWEET!
I WON. THEY TRIED TO GET IT TOO!!

@muddymuddymuddmann If I had nothing else to do I’d only be short 1 day. I have other things, though, so I lose a week. Sounds like your troubles are bigger than mine, though. Anyway, I learned something, namely that people will steal anything, even if they have no use for it, and even if they don’t even know what it is. I hope you get back on track soon.
@definitionofis THANKS
MUDDy
@BespokeGroupUK HA HA! GREAT LUCK TO YOU. ABOVE ALL, ENJOY.

@DIYMakerman NOW THAT’S A BIG BUMMER. I HAVE HAD TO START OVER ON 3 PROJECTS SO FAR DUE TO CAMERA TROUBLE, AND THEN ERRORS IN MEASUREMENTS. I HAD ANOTHER STIRLING ENGINE THAT I MADE BUT I NEED TO REDO THAT TOO. THE DISPLACER WAS NOT SATISFACTORY TO ME. LOWER POWER THAN I HAD IN MIND. BUT IT WORKS. HOW LONG WILL THE RE-CATCH UP WORK TAKE YOU?
MUDDy
@dave97202 OH…MAYBE I NEED TO LOWER THE AUDIO A BIT. LOL.
I THOUGHT YOU MIGHT BE TALKING ABOUT WHEN I WAS NARRATING WHILE THE DRILL WAS SPINNING.
YOU KNOW LIKE THE WHEELS SCREECHING AND THE ANNOUNCEMENTS COMING OVER THE NOISE.
I HAD A LOT OF FUN MAKING THIS ONE, LAUGHING ABOUT THE REACTION TO THE RED NECK METHOD OF TAPERING THE NUTS.
WWEEE!

When I saw 14:09 where you show the bearing and the weight of the rotor it reminded me of a problem which I had where starting torque was a problem. It became apparent that very tiny increases in starting resistance might not waste much power but they can prevent spin start up. You could measure it this way (my video): watch?v=zkVVGsB0bzg I give an amount that is too much. You can use that number. It is nearly universal for a given blade diameter.
@muddymuddymuddmann Those banana chips were made with barely ripe bananas. I’ve made more with riper bananas, which are sweeter, but need more time. I have something new coming up for the dehydrator. I’ll make another video, or two, once I get things worked out. I’ve run into a problem with the quern: some a-hole stole the one I was working on. I left it outside, now it’s gone. It’s of no value to anyone until it’s finished, but there you have it.
@muddymuddymuddmann The last half of the audio was very distorted. Which made it sound like the guy that announces the train arrivals and destinations in the subways.
@muddymuddymuddmann I’m glad you tried it out. 🙂 🙂
Good luck with the next one you build
Greetings
Erik
@rikkiesix HEY ERIK,
GLAD TO HEAR FROM YOU. THANKS FOR THE COMPLIMENT.
I MADE ONE OF THOSE STIRLING ENGINES WE TALKED ABOUT. I MADE A FEW MISTAKES BUT IT RAN PRETTY GOOD. NEXT TIME I WILL USE MORE WOOL, AND MAKE A SMALLER HOLE.
MUDDy
Great video man
You know your stuff well, and i like that
Greetings from across the ocean

@muddymuddymuddmann Any money that can be saved is a bonus. I’m lucky, I’ve got a mechanical fitters background, and like you I improvise quite a lot at home.I’m also lucky that my sister owns a scrap yard, and I’m always on the lookout for something useful to use. From what I’ve seen so far I might be able to scrounge everything except the resin.
