- I graduated from batteries, and am now going for electric motors, eh? In this video I build a small-scale replica of the world's first useful electric motor - the Jacobi motor. (No, I do not consider a bunch of solenoids pressing ink onto paper an electric "motor") I also replicated the use case that the Jacobi motor had - to power a boat!
Jacobi motor is a brushed direct current electric motor. It is also technically an axial flux type motor. And since I have figured that I'd like to design and build an axial flux type motor in the future, then going back to the roots with this Jacobi motor, made a lot of sense!
I hope you enjoyed the video, don't forget to like and subscribe!

Very nice build. Interesting to see a motor that doesn't use permanent magnets. I also really like that you integrated it into the boat and did some real world testing.
Really like your approach. It's entertaining, educating and I very much like the fact you integrate historical knowledge. Keep up the good work ❤
very impressive and educational as well
I just read up on Jacobi, pretty fascinating. Maximum power thereom, electrotyping (which I'd never heard of before, but which is fascinating) too cool, thanks birdbrain!
Jacobi is indeed a little known inventor and scientist, but one that does have a fair few cutting edge developments for their time, under their belt!
Is this a 3phase brushed motor?? The motor in the boat looks really 😎 cool, especially spinning slowly!👍😎 👍
No, this is essentially a brushed DC motor.
I like the sound it makes.
Can you make it brushless?
Its cool though never seen such before
This is a brilliant video.
Great video!
Very cool mate! How did your print handle the water?
It actually worked fine. I made sure to use an excess of glue between the joint segments to remove as many pinhole leaks as possible, and it seemed to work fine.
cool got to love it
remember me when your channel blows up ;)
very nice
Can you please make a bell electromagnet motor?
Cool! I love to learn. I am an artist and I share my painting demos and studio tours here. So much to see and hear on TH-cam. Have a great day!
somone needs to get this guy some rc gear XD
I looked at some setups but since I just recently made a DC power supply purchase, then I was a bit short on cash to spend more on this project haha.
@@BirdbrainEngineer ah I know that pain
if I had something lying around you could have it
but I only have transmitters and no recevers
what is the efficiency compared to today's engines?
Very very poor. I did not do any actual optimization, I just wanted to get something that works. I think the rough estimation I got was that if I put in about 30W of power(15V/2A), then I get about 1W of mechanical power out.
Simply taking away the stator coils and replacing them with similarly sized neodymium magnets would improve the motor manyfold... of course, in that case it would make sense to put the magnets on the rotor and control the stator coils instead, and control them electronically using transistors - that would make it into a brushless DC motor, hehe... and it's the type of motor I am working on right now :)
The only question to the author of the video: why politics again? It was an interesting video with good historical information until politics appeared.
