J.E.D. KleinNARRATOR
439:27
In the engineer shop, the electrical arc for welding all manner of metals and alloys.
J.E.D. KleinNARRATOR
439:34
In factories, steam power and mechanical transmission by shafting and belt is almost displaced by electric motors driving separate machines or groups of machines.
J.E.D. KleinNARRATOR
439:47
And even for the propelling of ships, electrical energy transformed from the mechanical energy of the steam turbine has been applied successfully.
J.E.D. KleinNARRATOR
439:55
We cook by electricity, do our laundry work by electricity, sweep our homes by electricity.
J.E.D. KleinNARRATOR
443:39
What a current of electricity is.
J.E.D. KleinNARRATOR
443:42
What we know today of the nature and interrelationship of electricity and magnetism has been explained in a previous chapter.
J.E.D. KleinNARRATOR
443:50
The electromagnet, in some form or another, is the basis of all machines for generating electric currents by mechanical power called dynamos, of electric motors, induction coils, and other applications.
J.E.D. KleinNARRATOR
444:05
The electromagnet is at the bottom also of all modern electric telegraphy and telephony.

You'll hear why the big AI bets are still waiting on business, not on chips.
Stephen ForteHOST
0:46
You'll hear the story of a factory ceiling, an electric motor, and a very calm engineer from 1899.
Stephen ForteHOST
0:55
You'll get the bill of work in my own words, and you'll leave with one question to bring to your next leadership meeting.
Stephen ForteHOST
1:00
One that might make the room very quiet.
Stephen ForteHOST
3:22
The line shaft decided where the machines went and how fast they ran.
Stephen ForteHOST
3:26
So where do you put the machines? You put the machines where the belts were, not where the work flowed best, where the belts were.
Stephen ForteHOST
3:32
Now you own that factory and somebody offers you an electric motor.
Stephen ForteHOST
3:36
What do you do? The sensible thing, you take out the steam engine, you bolt the motor onto the line shaft and you carry on.
speaker_0HOST
12:25
Bonding metal to smooth plastic.
speaker_1HOST
12:27
Right, because components like EV cooling plates and E-motor covers live in harsh thermal and vibratory environments.
speaker_1HOST
12:34
The metal layer doesn't just have to stick, it has to survive.
speaker_0HOST
12:37
And polyphenylene sulfide, or PPS, is really heavily favored for those environments, right? Because of its extreme dimensional stability, high continuous use temperature, and incredible chemical resistance.
speaker_1HOST
13:02
That is...
speaker_1HOST
13:03
Yeah, that's exactly what happens.
speaker_1HOST
13:04
So, Invallure utilizes specialized electroplating technology from a company called Biconex to process these PPS E-motor covers.
speaker_1HOST
13:13
The final finish is copper, followed by a thin nickel topcoat for environmental protection.
Ruth GoldingNARRATOR
64:41
The terminal of the peroxide plates, being the positive pole of the accumulator, is painted red and that of the spongy plates or negative pole black.
Ruth GoldingNARRATOR
64:53
Accumulators of this kind are highly useful as reservoirs of electricity for maintaining the electric light or working electric motors in tram cars, boats and other carriages.
Ruth GoldingNARRATOR
65:07
End of chapter 2.
Ruth GoldingNARRATOR
65:15
Chapter 3 of The Story of Electricity.

Ruth GoldingNARRATOR
71:38
A sensitive pile is also a delicate detector of heat by virtue of the current set up, which can be measured with a galvanometer or current meter.
Ruth GoldingNARRATOR
71:49
Piles of antimony and bismuth are made which can indicate the heat of a lighted match at a distance of several yards, and even the radiation from certain of the stars.
Ruth GoldingNARRATOR
72:02
Thermobatteries have been used in France for working telegraphs, and they are capable of supplying small installations of the electric light or electric motors for domestic purposes.
Ruth GoldingNARRATOR
72:14
The action of the thermopile, like that of a voltaic cell, can be reversed.
Eric BendlerHOST
7:21
This is where the whole industry has a problem that most drivers have never heard of.
Eric BendlerHOST
7:25
Most electric motors use permanent magnet motors, very strong ones made with rare earth elements like neodymium and dysporium.
Eric BendlerHOST
7:32
That's what makes an electric motor small, light, and efficient.
Eric BendlerHOST
7:37
The average torque on a new electric vehicle is over 400 foot-pounds.
Dan LongaugerNARRATOR
90:18
That power is electricity.
Dan LongaugerNARRATOR
90:20
Electric engines are now employed in mills and factories to drive all kinds of machinery, and electric locomotives are used on many railroads to draw great trains.
Dan LongaugerNARRATOR
90:32
an electric engine includes two main parts the dynamo which produces or generates the electricity and the motor through which the electricity is converted into power before an electric engine could be constructed it was necessary to discover a method of producing electricity in great quantities at small cost or to invent the dynamo and also to find a way to change with small loss electricity into power or to invent the motor besides a great deal had to be learned about electricity itself the electric engine like most inventions is therefore not the work of one man but of many men working at different times and in different countries the electric battery almost everybody knows a little about electricity very often on a cold day if one rubs his feet on a carpet and then touches another person a crackling sound will be heard and the person touched will receive a shock something like this happens when a cat's back is rubbed briskly despite these and other interesting things that have long been known not much interest was taken in electricity so that it was not until very recently that much was really understood about it men did not begin to study electricity with care until about two hundred years before washington became president otto von geiricke a german was one of the first to study it carefully he made the first machine to generate or produce electricity his machine was merely a globe of sulphur supported so that he could turn it by a crank when he placed his dry hand on the moving globe it would attract bits of paper like a magnet a similar machine was made later by placing a glass disk so that it could be easily turned and by fixing a number of rubber or silk brushes so that they would rub against the revolving glass alexander volta an italian was also a pioneer he discovered in eighteen hundred that two different metals in contact with each other would produce an electric current from this discovery he invented an electric battery it consisted of a number of cups piled on top of each other in each cup he placed a disc of copper and a disc of zinc covered with a brine of common table salt the copper disc of the first cup was connected by a copper wire with the zinc disc of the second cup and so on a copper wire was also fastened to the copper disc of the first cup and one to the zinc disc of the last cup on taking hold of these last two connecting wires a strong electric shock was felt and the current continued to flow regularly a battery like volta's can be made without the cups by using a glass jar it should be remembered however that the strength of the battery does not depend upon the size but upon the number of discs or plates volta's battery was the first easy way found to produce electricity in quantities years of study and experiment have shown also that the metals used by volta copper and zinc are the very best to employ in batteries the so-called dry battery for example used to work doorbells was made until lately of copper and zinc disks covered with sand or sawdust soaked in acid and sealed The battery is today the most common of electrical appliances.
Dan LongaugerNARRATOR

There are one or two in almost every home.
LilyHOST
