Cheers for that, Tony.
The cat was an Electrical God!

Anyuone know when shock and awe is back on I missed it first and second time around

 

[Knobhead]

The bit I can’t get my head around is in a two-phase system, surely it’s 50/50 which way it goes. In a way it’s like a three-phase motor working on one phase.
It’s to late at night to think any more on it.

For interest I just drew on a piece of paper two magnets with the fields reversing and rotating,do me a favour,when you work out the answer,let me know as well

Nicola Tesla was much more than the world has so far given him credit forHe was a giant,a genius,a man eons in front of most other famous inventors Thanks for that link Tony,it was very interesting

The only way I can think of doing it is with shading rings in each pole piece face. But that means the motor can’t be reversed.
There is mention in the film of copper rings by the poles so I think that must be it.

cheers tony good viewing

I agree!

I always had Faraday as the inventor of the (3 phase) induction motor.
So who actually did invent it? (can't be bothered googling)

I will build a Tesla Coil someday soon...

Maybe its just folklore, I have heard that he never wanted to patent any of his ideas, just to further mankinds intellect.

The secondary school I went to had a Tesla coil along with a Wimshurst machine and my favourite a Van de Graaff generator. It was a very old school, the chemistry and physics store rooms were like an Aladdin’s cave for me. I loved physics lessons. Chasing pools of mercury around the bench top was normal*. I even repaired the Wimshurst machine during my lunch breaks.

I can just imagine the HSE’s reaction today. Can’t do that…. Can’t do that…. Can’t do that…. Schoolboys mixed with 500,000V Can’t do that….

* It’s a wonder I’m even alive with some of the stunts we got up to. Pouring ¼LB of mercury from the palm of one hand in to the other.
The only accident I remember was a lad getting to enthusiastic with a burette and sucking sulphuric acid in to his mouth. His dad went mental, not at the school but at his lad for being so stupid. Dad was a research chemist.

Probably just me , but can not get the link to work ?
And Thanks Tony , that totally buggered up my early start day this morning , watching a excellent video .
But seriously thanks for that and please do keep them coming if you can !

Haha...2ndary school 71-8, happy days in the labs!
Burning gas from the taps, dissolving tongs in mixtures of concentrated acids (each bench had 2 or 3 sets of the usual 3), stealing sodium from the stores then burning ones desk back in the classroom, etc... and not a single item of PPE to be seen. We only had a Van d G.


A while back I've been playing with small scale Jacob's Ladders.
Got a 15kV Neon transformer, limited to 20mA, so perfectly safe, unless I'm typing this in hell.
Gap needs to be down to 2 or 3mm before an arc will strike. I really need a pole tranny.

My kids think me strange but I flippin loved me O level physics lessons
