KVAR-ENERGY CONTROLER

[NickD 202]

Triac! Now that's a freaking technical term flashback - the product I worked with was for lighting panels actually.

Not to sound completely, well, stupid - in super simple layman's terms why wouldn't the same hold true for say a compressor if everything was timed/tracked correctly?

Key to efficient motor design is to use high permeability extremely thin laminations to minimize eddy and hysteresis losses, large gauge copper wire to minimize I^2R losses, an extremely small rotor to stator gap that requires precision bearings and a robust rotor shaft in a suitable housing. Preventing any form of magnetic saturation that also adds to to making a more expensive motor. A good motor under no load conditions will have practically zero power input, hey, it ain't doing any work, but would present itself as a purely inductive circuit to the source where current lags voltage by 90 degrees. It's back electromotive force would practically oppose the applied voltage, so very little input current would flow, so even though the power factor was close to zero, would be very little load, apparent power would also be next to zero.

Nevertheless, when first started up with a dead rotor, would appear close to a short circuit to the source until it speeds up, for this reason, every motor requires a softstart circuit that disengages after the motor reaches it's rated rpm. This is what can be done, but isn't, have to knock every last cent out of current designs, but could find motors close to near ideal specifications made in the USA in the 20's and 30's when the cost of electricity was extremely high. Edison was charging a buck for an eight hour life light bulb when a full days pay was a buck. Did have a 3 phase 5 HP motor made in 1932 that took a crane to be picked up, today, you can put a so-called 5 HP motor in your back pocket.

So what is KVAR trying to do? My estimation is fixing ####### with #######. Knowing the history of one's profession was considered extremely important so you didn't reinvent the wheel, learned all the advantages and disadvantages, and made improvements. Completely opposite today, see kids in engineering, no future by the way, playing with computers and not even having the slightest idea of what they are doing.

My favorite part in the video is where they discussed UL, CE etc. Um they're safety standards, to ensure the device or appliances is suitable and safe enough to operate. Nothing to do with performance or whether it actually works.

In Australia, everyone gets free electricity.

Well we do use 240v, so were smarter on that front too. It's called future proofing and thinking ahead.

And everyone gets a free cell phone, landline, water, home, car, education, and all the kangaroos you can fuсk.

What really surprises me is what a gem like you is doing here? Why didn't you go to one of your own superior educational institutions?

Do you ever post anything worth 2 cents? Or do you just like to extend the level of discussion of EP to here?

Sorry, I forgot you were an intelligent America hater. Do you post anything that is true?

And you who got run of EP by Eric.

Nice try. What about your rebuttals to every else? Same sort of bullshit comes out of your mouth.

The fact remains that you haven't the balls to go one on one with Eric.

Does it really take balls to talk to Eric? Who in the heck is Eric? Well, enough of this nonsense, kiddies.

Never thought to look at ebay for KVAR Energy Controllers, a lot cheaper than their home site, even sell spare capacitors. Hmmm, dry capacitors, self healing, sure sounds like a cheap bipolar electrolytic, that box must be pricey. Some even contain DISCHARGING RESISTORS! Holy cow, a self contained discharging resistor, what will they think of next? Most are way in the lower microfarad values, can't do much with those for major inductive loads. But hey, it saves power, buy one, buy one now.
