Understanding RMF | The driving force behind every AC machine

Рет қаралды 659,574

3 жыл бұрын

Every AC machine uses a rotating magnetic field, an invention that kicked off the industrial revolution. Can you guess how the RMF reached this stage! In this video, we’ll travel through the minds of the geniuses behind the development of RMF. The greatest contribution can perhaps be attributed to Nikola Tesla, considered by many as the pioneering father of modern engineering. To understand how the design theories evolved over time, our trip will take us all the way through to a glimpse of modern-day winding techniques and RMF production.

It's not complicated enough. They had to make the arrow point to the south pole of the coils instead of how a compass is arranged pointing to the north pole? Is there a plan afoot to mix us up? Come on, people. Why do that? Just another small pebble in the road.

@Caishen Salelius 6022 My physics professors did not confuse us. There's another animated video out there that should be good too but suffers from the same thing. Too many moving parts with captions and narration. And music and sound effects. Interesting thing about knowledge and teaching. I think I'm seeing a good video or lecture when they explain things that I know already. But on further examination, I find that the explanations sometimes fail to explain clearly, things that I haven't learned. Our judging system is skewed a bit and tells us things that may not be true. PS. sorry this is so windy.

Tesla built the first a.c motors, but Charles Steinmetz, head of the original General Electric research laboratories, made A.C power transmission engineerable with his mathematics and theory, and therefore made the use of A.C possible. Before that Oliver Heaviside took Maxwells equations and simplified them to four short expressions; Maxwells equations as we are taught in school should really be called Heavisides equations. He also made telegraph transmission possible by describing the mutual relationship between magnetic and dielectric fields. He showed through his telegraph equation that the problem with telegraph transmission was not solvable by loading the system with more power, but was only solvable by intoducing loading coils at certain intervals along the line. Just a few names no one hears anymore.

in my opinion the 3 phase wiring is more of an evolution than a revolution to the design tesla created, not to say it wasn't a big deal, but they just used what tesla had already figured out and improved it to make it more efficient

Even the two phase was an evolution of Bailey’s original step change design. The fact that you could have a single vector and have that move, whether in stepwise or continuous fashion, by altering the current was his idea.
