The disassembly information of the three major parts of Tesla electric vehicles (battery, motor, and control) on the Internet is no longer available. There are relatively many technical articles and videos on the disassembly of batteries and motors. I will not elaborate here, but I will focus on introducing the motor. Drive control system.
1. Comparison of Tesla Model X and Weilai ES8
1. Tesla Model X four-wheel drive solution
2. Domestic four-wheel drive solution
2. Tesla Model X electric drive system The previous generation of Tesla used a rear-drive large-drum-type controller. There are many materials described on major networks, and the relative volume is also large and complicated, as shown in the following figure:
Now the focus is on the new generation of electric drive system assembly. The front and rear drives are basically the same, but there is a difference in the suspension. The new generation of electric drive system, which integrates the motor, reducer and electronic control, is very compact and the motor part As large as a watermelon, the motor power can reach 300KW. The electrical control part is as follows:
1. The overall shape of the controller
The following is divided into layers, which are roughly divided into three layers: the first layer is the main control part, referred to as the control motherboard. The MCU uses TI ’s TMS320F2611P8KO chip. In order to achieve fast and powerful computing and processing capabilities during high-speed operation, it also uses An ACTE's LA3P125VQG100 chip is used together to ensure the stability and reliability of the system. More detailed motherboard hardware will be disassembled separately and a schematic diagram will be produced next time. The front and back of the motherboard are as follows:
The third layer is an IGBT module, which uses INFIEON's single IGBT, AUIRGPS4067D1, a single current up to 160A, a total of 36 chips, a water cooling device, and the left and right 6 holes are designed for water-cooled import and export.
The lower part is the thin film capacitor part. In fact, it can also be counted in the third layer, because it is soldered together with the IGBT board. The thin film capacitor is TDK's 220U / 650V custom capacitor.
In general, the Tesla controller solution is very compact from design to assembly. Whether it is hardware technology or production process, there is no lack of an Elon Musk strategy and craftsmanship.
Educational projectors are mainly aimed at classroom teaching by school teachers; traditional projectors are not easy to carry. Due to the naughty students in school classrooms, projectors are not safe to place in classrooms and are easily damaged by students. The portability of educational micro-projectors makes up for teaching Vacancy, it is convenient for teachers to give lectures and only need to store the materials in the projector and show them to students for teaching, saving the trouble of textbooks and handwriting with pens and chalks. Its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling.
Educational projectors need to have:
1. Clear handwriting Educational projectors most often display text and images, at least a resolution of 1024*768 or more, and a contrast ratio of more than 3000 lumens, so that students in the back row can see the projection clearly
2. Short-focus large screen;
3. Accurate color;
4. Easy operation;
5. Features such as multiple connection methods.
