Chapter 231: Laboratory

In the factory building of the Shaoxi Mansion, Li Xiang has now built another laboratory, ready to be used to develop new things. Pen? Interesting? Pavilion wWw. biquge。 Looking at the various equipment that had been prepared in front of him, Li Xiangyan felt very satisfied.

There is also a table in the laboratory, at this time all the parts on the table have been neatly placed, these parts are made according to the specifications required by Li Xiang, I heard that Master Li wants these things, the deputy envoy of the capital immediately dispatched four highly skilled craftsmen to make the mold, and it only took two days to complete the production of the iron core.

As for the copper wire, it is also put several rolls, these copper wires are in accordance with Li Xiang's requirements, pulled to a diameter of about a millimeter thickness, if accidentally pulled off halfway, then by the craftsman to re-weld up, so these rolls of copper wire in front of the surface in addition to the surface of the insulating paint, basically not much different from the enameled wire of later generations.

Next, the trial production of the battery is the first step, and Li Xiang is very careful in this operation process. Because the copper plate and the zinc plate have been cast with a bracket, so they can be placed very stable, a few people put the copper plate and the zinc plate first, and then Li Xiang connected two thicker copper wires, and make the two wires completely away from the short circuit, and then let Fan Wenjin and Xu Yonghong slowly pour in dilute sulfuric acid, and when Li Xiang calibrated the scale, the preparation of the battery has been completed.

Li Xiang has no doubts about whether this simple battery can work, the key is to see how much power it provides. At this time, in the face of this huge battery, Li Xiang didn't know how big its current was, so he didn't dare to try it casually, but it is estimated that the voltage should be within 2V.

Li Xiang found a section of the thinnest copper wire, and then gently touched the two copper wires connected to the electrodes to the two ends of the copper wire, only to hear the sound of "pop", after a small spark flashed, the thin copper wire was actually hit into two sections, and the section was obviously melted by high temperature, and several people were taken aback when they saw this situation.

Seeing that this battery can provide such a large current, Li Xiang didn't dare to be careless for a while, hurriedly took the lead off the battery, and carefully did a simple insulation work, so he was relieved, thinking that the power of this battery short circuit is so great, it seems that it is many times stronger than the No. 5 rechargeable battery in later generations, and even has caught up with the battery.

In fact, Li Xiang didn't know, this kind of battery because the plate is designed to be large, so in the short circuit, its short-circuit current is naturally large enough to fuse the copper wire, and the car battery of later generations will break the 5 mm gong wire knife is normal, although the simple battery made by Li Xiang now is not much worse than the battery of later generations, but it is not much worse, at least in the maximum current and the small battery of 30 ampere, but the battery in front of him has less than 2V voltage.

Now that the battery has worked, the next step is to make a load, that is, a simple motor designed by Li Xiang. The winding work of the rotor is the most complicated, Li Xiang still decided to make a winding for each person, so he explained the winding method in detail to the two senior craftsmen of the Duzuo Academy, who also learned quickly, and after a while they understood what Li Xiang meant.

The winding core must be wrapped with oil paper and the copper wire and the rotor contact short circuit, and then the copper wire is wound with a layer, and there should be a spacing between the copper wires for insulation, and after a layer of copper wire is bypassed, then a layer of oil paper is wrapped, and the second layer of winding is started, and so on many times, and finally each winding is wound hundreds of times, and has the same number of turns, and the production of the winding is completed.

Then, the three windings should be fixed on the wooden shaft, two by two into a 120-degree angle, and then the adjacent two groups of taps are connected, there are three winding electrodes, and these three electrodes are also evenly surfaced at an angle of 120 degrees. In this way, the rotor is finished.

By the time the few people finished making the rotor, nearly three hours had passed, and the next step was to make the stator. Because the Song Dynasty fashion could not make a certain shape of permanent magnets, Li Xiang had to have people collect dozens of small natural magnets, and then carefully fixed these natural permanent magnets on the stator, so that the stator formed a ring-shaped rotating magnetic field, so that the stator was completed.

In fact, according to Li Xiang's original plan, he was going to use a coil to wind the electromagnet as a stator, and later felt that this stator was too troublesome to make, not to mention that this motor was only an experimental nature, one was to test whether the battery could work, and how much capacity the battery had, and secondly, it was also for demonstration to everyone, so he gave up this idea and just used some natural magnets.

Since many of the parts were made according to the design, the trio had no trouble installing them, just assembling the components and tightening them, but by the time the entire motor was assembled, nearly six hours had passed. Unable to eat, the brushes were adjusted and then connected to the binding posts of the wooden base. At this point, this simple motor is finally completed, and now it is almost connected to the battery for testing.

Li Xiang held his breath and carefully turned on the power supply, but the motor did not start to rotate as expected. Now it can be determined that there is a current in the motor, because Li Xiang just appeared, the rotor coil has been slightly hot, and the resistance to rotate in a certain direction is significantly greater than the resistance to rotate in the opposite direction, obviously the whole motor has basically no problem, it should be due to the insufficient battery voltage.

So a few people made the other two batteries according to the method just now, for the sake of insurance, Li Xiang decided to connect the two batteries in series first, as expected, at this time the rotor of the motor has slowly rotated, because the three people paid special attention to the ****** problem when winding the rotor, so the rotor rotated quite smoothly, but it rotated a little slowly.

At this time, the eyes of the two senior craftsmen were straight, at first when winding the rotor, the two of them had vaguely guessed that this might be an automatic machine, but now they saw it with their own eyes but it was a different feeling, for a while the two were stunned, and they forgot to speak, until Li Xiang turned off the power supply, this came back to their senses.

Li Xiang saw the two of them, and was not surprised, but had an inexplicable excitement, he decided to add a battery to try, so that after the three batteries are connected in series, it should be able to reach a voltage of five to six volts, but in this way, the current is also stronger, so Li Xiang is also very careful when operating, for fear of accidentally hurting himself. In order to prevent accidents, Li Xiang told the two of them to stay away again, and then turned on the power again.

As long as this test is successful, the relevant materials can be compiled into technical documents and handed over to the craftsmen of the Tosakuin to make and form mass production, which is the driving force of industrialization.

After all, if you use a super 3D printer for everything, you can't promote industrialization, not to mention that the resources of super 3D printers are limited. (To be continued.) )
