Thank you! I have an illuminated sign from the 1960's that uses an Eddy current motor in the "light chaser" that opens and closes contacts to change lights on the sign. Your video is helpful in understanding how it works.
If one looks at an induction motor torque curve, it has a peek torque at somewhere around 10% slip below synchronous, and induction motors are generally rated for continous operation at around 5% slip below synchronous. But if an induction motor is spun faster than synchronous, it is in the generating portion of its torque curve. It would be interesting to see this motor turned into a generator by spinning it maybe 10% faster than it wants to motor. What is pretty neat in this induction motor is that it's speed is variable. Induction motors with wind turbines get a bad reputation in part Because of needing grid excitation or self excitation with capacitors to absorbe and provide reactive currents. But another issue is that wind energy and RPM is highly variable. And what I find exciting in this motor is variable speed. Maybe there's a way to regulate its syncronouse speed to be about 5% slower than what it is made to spin at. Or maybe this is simply way too inefficient and hopelessly impractical to design for and generate reasonable amounts of power.

I enjoy your videos very much. Very educational. I like the short format. Good work Grain.
2:26 brilliantly simple tool for finding the center. It is a perfect solution to a problem I'm facing.

Спасибо за видео. По
физике в школе изучали только теорию а здесь прекрасное наглядное пособие. Ещё раз спасибо.
Такая мелочь ,а сколько инструмента нужно))
Красота требует жертв))
этточно! (с)
Nice Job.
Какой хороший канал.
Сколько интересного👍
Very nice build - Thanks for sharing!!
Вот так и живём))
Просматривая интересные идеи друг у друга))
Super
You have a very excellent form of presentation/explanation. Are you a teacher by trade?
Thank you, no, I'm not a teacher.
Pe acest principiu erau odată construite contuarele de curent , frumos
Muy bueno e interesante, saludos amigo.
Fascinating stuff
That is so cool.
Very nice 💜
Nyc❤️
👍👏👏
Excellent demo. Thank you.
Pleas drill the steal slower so fast it isn’t good for the Drill and the Machin
Частоту поднять быстрее крутить будет
☺️
