AC MOTORS

AC MOTORS - Department of Defense 1969 - PIN 39947 - AC MOTORS ARE SHOWN IN VARIOUS APPLIANCES AND ELECTRONIC EQUIPMENT TO EMPHASIZE THEIR WIDE USE AND IMPORTANCE. AN ACTUAL MOTOR IS DISASSEMBLED TO POINT OUT EACH PART AND THE SIMPLICITY OF CONSTRUCTION. THE PRINCIPLE OF OPERATION IS DEMONSTRATED, POINTING OUT THE MAGNETIC FIELD AND MAGNETIZATION OF THE ROTOR. A ROTATING MAGNETIC FIELD IS PRODUCED THROUGH A DEMONSTRATION. INDUCTION FROM ROTATING FIELD TO WIRE LOOPS IS DEMONSTRATED, FOLLOWED BY EXPLANATION OF HOW THE ROTOR IS MAGNETIZED. CONCLUDES WITH A DEMONSTRATION OF SLIPPAGE AND ITS RELATIONSHIP TO INTERNAL AND EXTERNAL LOADING, AND AN EXPLANATION OF A TYPICAL TORQUE CURVE.

Tesla is a GENIUS!!!!

[TheCerberusInferno]

This video is excellent !

[windoes98se]

induction motor FTW simple yet robust

[Lorentz5]

it's amazing what clever techniques they employed to demonstrate these concepts without ever having access to flash / animation software

@psychotickable  HA! LOL SORRY ABOUT THAT!

@Caleidus I think the evidence is all there and in favor of Tesla. Look at where he was and what he was doing before ferraris claim in 1885. Look at what he went on to do. History and dates are not just plucked from Tesla's journal. It directly correlates to where and what Tesla was doing at the time. I have much info on Tesla his books and patents and he is a clear genius so to suggest he was a plagiarist is absurd. He only wanted credit for his own work. Good conversation by the way :)

@psychotickable Everyone can draw the working principle of an induction motor or even building a simple model in a few minutes, why Tesla didn't do it in 1882? Tesla was obsessed with being recognised as "the first one" so why he waited 6 years before patenting his conceived idea? There are no evidence at all that he created something in 1882. No one can get the paternity of an invention just because he writes in his own autobiography: I invented this in this year and u have to believe me.

@Caleidus The evidence was that Tesla completed the first ever polyphase AC induction motor in 1883 and showcased it in front of many in France well before 1885. Tesla was adamant that a commutator wasn't necessary whilst at college. Tesla was in New York at 1884 already with working concept. The history dates and future discoveries all suggest Tesla deserves the credit. He was more than skilled enough to do it and he proved it. I don't think Tesla was the type to take credit for others work.

@psychotickable 1915, Tesla wrote in his autobiography that he "dreamed up" about induction motor in 1882, by chance 3 years before Ferraris experience. No evidence support this claim. It was evidently an attempt to ripp off Ferraris by showing that he pre-dated him. Ferraris was a gentleman, the true forgotten genius, who never wanted to patent his inventions since he thought that none should take advantage from science. Tesla took advantage of Ferraris's honesty....

[psychotickable]

@Caleidus 1882 Tesla had the concept. 1885 Galileo Ferraris researched the concept. 1888 Tesla gained the patent. Edison loyalists will discredit anything Tesla then and now.

[psychotickable]

@acika72 Was? lol

[Caleidus]

Galileo Ferraris invented AC motors. Tesla just stole the idea
