The semi-cylindrical shell of the magic machine suddenly turned into a frosty white, shrouded in a thin layer of ice, and then the ice dissipated, and there was a bright red color that only appeared when the metal was heated, and even some changed to golden yellow, but before the shell melted, the signs of heat dimmed again, and the shell of the magic machine was covered with white again, and then the white dissipated, and the bright red reappeared, and so on, white to bright red, bright red to white, and the frequency of change became faster and faster.

After the battle to guard Lobit, Philip also had a slight sense of magic, and he felt that the water and fire magic were constantly changing back and forth, and if he didn't guess wrong, there must be something wrong with the magic machine.

Through the opening in the shell of the magic machine, Philip noticed that the connection between the rotor that rotated the gear shaft and the contact brush was reciprocating with a blue glow representing the water system and a red glow representing the fire system.

"My lord, run, the result of the magic disorder is an explosion!"

When the two of them ran from the laboratory to the back garden of the Lord's Mansion, the Lord Lord and the Goblin Master worked together to close the iron door of the explosion-proof laboratory, which was half the length of a human arm's length, and then bolted the door from the outside.

The two of them were standing outside the laboratory, and Moz looked at Philip nervously: "My lord, can you resist it? The explosion caused by the magic disorder is bigger than the explosion produced by the magic cannon." ”

"Yes, maybe, maybe, in order to study the Crystal Cannon, I added another layer of bricks outside the lab. “

As soon as he finished speaking, Philip heard a low muffled sound from the laboratory, and then, as if someone had kicked the thick iron door from the inside, a bulge flew out of its original closed position, and smashed a tree and fell heavily to the grass.

Philip swallowed and smiled dryly, "It seems that at least one more door will be added." “

When the two of them walked into the laboratory again, Philip saw all kinds of debris that had almost exploded into powder, except for the magic machine, all the tables, chairs and benches in the laboratory were all dead.

"How did I forget that DC motors are the most problematic!"

Philip said secretly in his heart.

In the earth, the DC motor has the advantages of high operating efficiency, convenient and flexible control, precise control of displacement, good smoothness of speed regulation, large reversible rolling mills, mine winches, high-speed elevators, gantry planers, electric locomotives, city trams, subway trains, electric bicycles, large precision machine tools, etc., but it also has a fatal shortcoming, that is, the maintenance is complex, especially the part of the carbon brush is easy to produce sparks, which leads to motor fire or short circuit of the line.

In this shijie, some characteristics of magic energy and electrical energy are similar, but when Philip drove the DC magic motive through the DC magic energy in the magic crystal, he didn't see anything similar to a spark, thinking that there was no such thing, but he didn't expect that when he used the cold wind magic array to cool the circuit of the magic machine, there was a magic disorder, and the final consequence was even more serious than the burning caused by the spark.

Explode!

"You have to use the AC magic machine!" Philip said to Moz: "You have the drawings of the magic machine, assemble it in the form of the AC magic machine, and find Miranda for any materials you need, anyway, Ivey lost 30,000 gold coins, spent 10,000 yuan on the bereavement of the fallen soldiers, spent part of the repairs to Lobit and the rewards for the various tribes, and there are more than 10,000 left, you just have to buy the materials or something." ”

"But my lord, two days ago, we shiyan the exchange magic machine, relying on the High Elf mage to deliver magic energy to it, unable to drive the heavy excavator, the bucket unable to lift, and the excavator unable to walk. ”

Philip shook his head, "In any case, we must follow the path of the AC Magic Machine, its insufficient output capacity can be solved by adding mages, or other methods, at least, its inherent shortcomings are not as obvious as the DC Magic Machine. ”

Philip frowned and thought for a while, and said, "I thought about it just now, weishenme before you attacked Ivey, there was no problem with the DC magic energy machine on the excavator, and as soon as I installed the cold wind technique, there was a problem. DC magic machine because in the end when the rotor rotates, the energy in it is actually AC, DC must be used when turning AC, that is, the metal block between the wiring and the rotor, with this thing, because the friction and the continuous switching of the direction of magic energy is bound to produce heat, and this heat I estimate is the fire magic element, if we don't care about it, this magic energy will become heat dissipation, you also found when using the excavator, with the increase of heat, the magic crystal consumed by the magic machine will increase exponentially over time, if it is used for a long time, even if it is just to give this excavator function, there are not enough magic crystals in the whole continent. If we use cooling magic such as the Cold Wind Technique, the collision of the water magic elements and the fire magic elements in the small space inside the magic machine will cause a magic disorder, and zuihou will cause the magic machine to explode. ”

"So!" Philip clenched his fists firmly and said, "In any case, we must develop the AC magic machine, even if the current use of the AC magic machine is not as good as the effect of the DC magic machine, we must also be firm in this direction of development." ”

Philip also had some words not to Moz said, on the earth, weishenme AC motor use is wider than DC motor, in addition to reliability, AC motor does not have sparks on the carbon brush, AC motor manufacturing process, maintenance is also smaller than DC motor, in addition, there is a very important factor, on the earth, the power grid is AC, no matter which country, the use is AC power grid, not the expensive DC power generation system and DC power grid.

In the future, Philip also hopes to establish an AC power generation network, on the one hand, let some giant beasts drag large magic energy machines to create magic energy, and on the other hand, use equipment such as excavators, connect to the magic energy transmitted by magic energy machines, and directly drive the magic machine and then drive the excavator.

Just as Philip was about to discuss further with Moz how to build a communication magic machine, Franklin appeared in the garden and hurried towards Philip with a red tide of excitement on his face, and a thin piece of paper waved in his hand: "Good news!amazing good news!!"
