Trams, vehicles, machine tools, automatic doors, buses, electric rolling brakes, textile mixers, CD-ROM drives, printers, washing machines, water pumps, additional information, motors and generators have basically the same principle, but their energy conversion directions are different. The cooperation of motor, power electronics and microcontroller has formed a new science called motor control.

On the Principle of Motorcycle (II) After talking about motorcycle (I) in the last issue, I believe many readers have begun to understand motorcycles with remote control, but if you go out to buy or want to participate in a competition, you may encounter some problems immediately. A reader wrote to ask the stationmaster what a stock motorcycle is and what a 23T motorcycle is, and whether all 23T motorcycles have the same speed. Let's start with this in this issue. Readers who read the last issue of 23T will probably know T's explanation, but you will find that many novice competitions will take 23T or stock motorcycles as the limit of the competition. Why is there such a restriction? And what is the solution of stock 23T? In fact, the most basic explanation of the 23T is that the axis of the motorcycle has circled 23 times. Because 23T has a good performance in power saving or speed control, some remote control car competition groups, such as JMRCA, began to use it as an indicator of novice or fair competition. On the other hand, it is well known that thick and thin lines and magnet strength will affect the results, so JMRCA and JRM began to define the so-called stock friction. The most basic definition of stock is that when winding 23 or 27 times, the core must be wound by machine, not by hand, the thickness of copper wire must be 0.8mm, the angle of entry should be less than 20, the diameter of copper head is 8mm, the core cannot be changed, and the ball beer bell cannot be changed. Motorcycles manufactured under these conditions, as long as they are approved by JMRCA, are regular motorcycles in stock. End Bell Maybe you don't understand the above definition, what is the angle of entry, or want to know how to improve the strength of existing motorcycles. Next, the stationmaster will explain another part of motorcycles: End Bell. Actually, End Bell refers to motorcycle cover, but this motorcycle cover is also very important for motorcycles. When we take the tail bell apart, we can see that there are several parts: carbon eraser, slingshot, bearing beer bell and rubber tail bell. Some parts will have heat dissipation metal parts and some small capacitance resistors, and some parts will not. Let's put these questions aside. Carbon wipe first, carbon wipe. Maybe when you see a charcoal eraser, you can't help asking, why is it called a charcoal eraser when it is obviously metal? In fact, the main material of carbon eraser is graphite, because graphite is not only hard, but also has lubricating effect, so it will be made of graphite mixed with silver or copper, so it is called carbon eraser less. Carbon eraser is a part that directly contacts the axis of motorcycle, and it is a very important link. In the general unreformed environment, the better the contact between carbon brush and friction, the greater the theoretical current and the better the magnetic force. However, because the axis of motorcycle is rotating, the greater the contact surface, the greater the wear and resistance of carbon brush and copper head, and the more power is consumed. So you will find that when you use rubbing for a period of time, the copper head will turn black, and you need to clean the copper head to give full play to the proper ability of rubbing. In this regard, there are some specially designed carbon erasers, such as horizontal stripes and diamond stripes. The bar is the most popular, and its performance is good, which is very suitable for general competitions. As for the diamond-shaped carbon eraser, it has the best ability, but because of its unique design, it will scratch the copper head of the motorcycle shaft after a period of use, and even it is useless to clean the copper head, so it is only suitable for some super-rich users who only plan to use the motorcycle once. Seeing this, you may understand how to improve the stock of motorcycles. Yes, it's on the charcoal eraser, because it's the only place you can change. However, it should be noted that not all carbon erasers are available. The size of the carbon brush used by Stock Moda is different from the general one. Be clear about the use of stocks. In addition, the tightness of the slingshot is also a noteworthy place. As for the function of beer bell, the angle is to make the motorcycle rotate more smoothly, while the welding of resistor and capacitor is to keep the motorcycle power and reduce the interference to reception. What about the entrance angle? The angle of entry is actually a delicate issue. The so-called incident angle is based on the horizontal friction magnet and carbon brush, and the angle formed with the rotation of the shaft is called incident angle. The function of feed angle is to increase the power-on time of motorcycle. The greater the water entry angle, the more electrified rooms, the better the friction and the greater the number of revolutions. However, the longer the angle, the darker the copper head of the motorcycle. What's more, if the motorcycle runs in the reverse direction, it is not allowed to have a large angle, otherwise it will hurt the motorcycle and even burn out the electric transformer. Is there a winning or losing angle setting? The stationmaster can say: I don't know myself. Because this is related to the quality, hardness and heat resistance of carbon brushes, it must be an experience, or it must be tested by readers and players themselves. What is refitting a motorcycle? Many friends, including stationmasters, are eager for these motorcycles, but whether these motorcycles are "wild" depends on the following and then judge for themselves. The so-called modification, very simple, is to modify the motorcycle. Then why reform? Of course, I hope I can turn faster and better! Ok, but theoretically, if you know a good equation, you can mass-produce it without modification. Some insiders said that in fact, the so-called modified motorcycles refer to some motorcycles that have problems in production and have been pulled out for manual modification to make them "return to normal", and the weight difference between the two sides is closer to zero. The most common practice is to drill holes in the shaft of motorcycle to make up for the uneven weight on three sides during production. Therefore, it is absolutely possible for you to find that you have drilled two holes and one hole on the motorcycle shaft at the same time. It is good to say that it is to create better motivation through improvement, but it is not good to say that it is to make up the pot. See if you believe the slogan of "Seiko Manufacturing Motorcycles" of motorcycle manufacturers. Speaking of this, readers believe that they will have a further understanding of remote-controlled motorcycles and can choose a suitable motorcycle more clearly. Therefore, the webmaster will explain the most fascinating new technology-the principle of carbonless rubbing and rubbing in the next summary article on the topic of rubbing (3). Remember to pay close attention to the launch date! Supplementary note: ... its principle is that the bullet is generated when it is fired ... Volt is the working voltage.
MAH is its capacity.
The rotation will be slower at low voltage.
For example, compared with 9.6 volts and 8.4 volts.
When using 9.6 volts, the motorcycle will rotate faster than when using 8.4 volts.
The larger the mAH, the longer the service time.

In fact, the principle is very simple. The following is the motorcycle driving sequence. 1) The battery is powered by the positive and negative poles of copper wire. 2) The motorcycle converts the electric power of the battery into power.
And connecting the gear to the steel shaft of the motorcycle by utilizing the rotating power applied to the steel shaft from the motorcycle.
4) Connect the front and rear axles of the electric toy car to the gears 5) Install four wheels on the two front and rear axles 6) Start by friction.
Toy cars can walk.
