boomers will be dead in 20 years and no one will know who Abba was
No-one is alive now was alive when Mozart or Chopin were composing either.

What is up with these supposed brushless motors. I call foul and highly suspect. But major tool mfgs make them or CLAIM it. And I, during recent Christmas, saw "they" are even using them in R/C toys for kids!

I am stuck on 50Hz. A Herckts is juan cycle per second right? The queston seemed to be about running motors @ 50Hz, but itold bee the generator spinning at 50 whips a sec that detrimines the speed of the A/C,not the motor at the end?
I am suddenly curious to know what speed the generators in US power plants commonly spin. Gut seize 60Hz, but Nautical Shore...
QuoteUnlike toys and flashlights, most homes, offices, factories, and other buildings aren't powered by little batteries: they're not supplied with DC current, but with alternating current (AC), which reverses its direction about 50 times per second (with a frequency of 50 Hz). If you want to run a motor from your household AC electricity supply, instead of from a DC battery, you need a different design of motor.
In an AC motor, there's a ring of electromagnets arranged around the outside (making up the stator), which are designed to produce a rotating magnetic field. Inside the stator, there's a solid metal axle, a loop of wire, a coil, a squirrel cage made of metal bars and interconnections (like the rotating cages people sometimes get to amuse pet mice), or some other freely rotating metal part that can conduct electricity. Unlike in a DC motor, where you send power to the inner rotor, in an AC motor you send power to the outer coils that make up the stator. The coils are energized in pairs, in sequence, producing a magnetic field that rotates around the outside of the motor.
How does this rotating field make the motor move? Remember that the rotor, suspended inside the magnetic field, is an electrical conductor. The magnetic field is constantly changing (because it's rotating) so, according to the laws of electromagnetism (Faraday's law, to be precise), the magnetic field produces (or induces, to use Faraday's own term) an electric current inside the rotor. If the conductor is a ring or a wire, the current flows around it in a loop. If the conductor is simply a solid piece of metal, eddy currents swirl around it instead. Either way, the induced current produces its own magnetic field and, according to another law of electromagnetism (Lenz's law) tries to stop whatever it is that causes itâ€"the rotating magnetic fieldâ€"by rotating as well. (You can think of the rotor frantically trying to "catch up" with the rotating magnetic field in an effort to eliminate the difference in motion between them.) Electromagnetic induction is the key to why a motor like this spinsâ€"and that's why it's called an induction motor.

With Epstein having the goods on both Clintons, I don’t expect him to live much longer.

More of your fake news meant to divert attention from the real criminals that you pimp for on a daily basis here.

That would be awfully kind of you! There are so many suggested variations: spices vs. none at all, fruit as raisins only, or currants only, or both plus peel (where I can never tell if you guys mean mixed lemon and orange or what we call citron here and sukat/succade in Norway which is something else entirely). It would be wonderful to reproduce one from a specific bakery.

Everyone heard the revolting audio of you recently slurping gasping and belching like a pig in a trough.

So, she didn't bring the coffee grinder because that would be FAR too heavy and cumbersome! Whence comes the obsession with waffles anyway? Toast not good enough?

I had to hire someone else, you no longer fit into your outfit, even with the corset. One too many waffles, dear boy!
Seriously, who takes a fucking waffle iron on holiday with them? Did she bring the deep fat fryer too?

Thanks for risking the (rather weak) wrath of SV...
I really have not looked at much about UK wiring, and it is interesting to learn a little. I only know about 50Hz because I had a very expensive piece of equipment come from Germany. It had a completely universal voltage 250HP motor. However, they were supposed to use different size sheaves (pulleys for the belts) when shipping to different countries. I eventually tracked mine down to having the "gearing" to run at 50Hz instead of 60. The end equipment was being driven at excessive speed...
Let's just save everybody the time...

That one incident isn’t pizzagate, even though you’d like people to think it is. Once again, weak shit.
