The use of a miniature motor in an automobile The role of a motor is to convert electrical energy into mechanical energy that drives the operation of the device. In the car, except for the starter that starts the engine, all the motors that are distributed in various parts of the car are miniature motors. In the past, automotive micromotors were used only as power sources for wiper assemblies, windshield washers, electric oil pumps, and automatic antenna assemblies. Nowadays, the sedan is pursuing passenger comfort and automatic maneuverability. Micro-motors have become an indispensable part of modern cars. Some cars have more than 20 miniature motors installed. The movable equipment usually has a miniature motor as its power source whether it is doing round-the-week motions, or making horizontal swings, or making linear movements. For example, the position of the electric seat cushion moves, the angle of the backrest and the headrest changes, the swing of the rearview mirror, the washing of the headlight, the opening and closing of the window, the operation of the electric vehicle door lock, the rotation of the radiator cooling fan, and the like. Automotive micro-motors, as their name implies, are miniaturized DC motors, which typically have a power of less than 100 watts. Due to the special requirements of the car's operation and the harsh environment, the user's requirements for the car's micro-motors are demanding. For the motor, the key to the quality of the motor is the magnetic material of the movement, in addition to the design structure and processing technology. At present, the new motor used in cars uses a permanent magnet material containing rare elements. Its main components are iron, boron, bismuth, etc. Its magic lies in the strong magnetism, no matter what shape it is processed into, the magnetic properties are better than ordinary ones. The ferromagnetic material is 2 to 10 times stronger, which means that the motor made of this kind of permanent magnet material has large power, small size, light weight, and high efficiency. The micro-motor is used in a large number on the vehicle and the weight of the whole vehicle is relatively reduced. , is equal to improve the carrying capacity. Roger Smith, the former president of General Motors, once said that nowadays the automotive industry cannot do without electromagnetic materials. For industries using magnetic materials, electromagnetic materials are as important as semiconductor materials for the electronics industry. Each of the major breakthroughs may change our lives. The responsibility of the micro-motors of automobiles is to drive the movement of equipment. Therefore, a set of conversion mechanisms is generally required to perform deceleration and change of direction. For example, the wiper motor servo mechanism adopts a worm gear drive mode to decelerate and change the rotation of the electric axis. The central control door lock motor adopts a rack and pinion transmission mode, which serves to decelerate and change the rotation into a linear movement. These forms are more commonly used transformation mechanisms. The use of micro-motors in modern cars is increasing. Micro-motors must be used in some cars' ABS systems, electronically controlled suspension systems, electronically controlled power steering and electronic throttles. With the development of automotive electronics, micro-motors are becoming increasingly important.
Can you boost your WiFi signal with outdoor 4G CPE?
When you travel or go to some remote areas, you may be annoyed by poor reception. Is there any way to get a strong WiFi router signal outdoors in a 4G LTE network? Very good, outdoor 4G CPE router would be a good choice!
What is an outdoor 4G CPE router?
An outdoor 4G CPE router differs from a Wifi-only router in that it needs to be connected to a fiber optic network. The 4G CPE WiFi router can pick up the carrier's 4G LTE network signal and convert it into broadband and Wi-Fi. Just plug in your SIM card with your data plan and enjoy a stable and reliable WiFi signal with family and friends. This Outdoor CPE can be used in harsh environments. If you install your router outside or near a window in an area with a weak 4G signal, your device can receive a better 4G signal.
Second, what are the characteristics of outdoor 4G CPE router?
1. Better network for ODU and IDU
4G CPE outdoor routers include an outdoor unit (ODU) and an indoor unit (IDU). Help your device receive the best outdoor cellular signal through the ODU, and connect to the indoor WiFi router through the network cable to experience better network speed. As shown in the figure below, an outdoor LTE CPE (ODU) is installed outdoors and connected to an indoor Wi-Fi router (IDU) via a network cable. The entire 4G device is powered by POE. This data will be transmitted over the same Ethernet cable, eliminating the need to connect the ODU to a power outlet.
2. High-speed multi-user available
The outdoor 4G CPE features a built-in 4G LTE modem and a 5dBi high-gain antenna. LTE CAT4, download speeds up to 150Mbps, WiFi speeds up to 300Mbps, can connect 32 users at the same time. The high-gain antenna of the outdoor 4G CPE router enables it to have higher power and stronger signal transmission and reception capabilities than mobile phones. Therefore, the CPE router can receive the signal. If your phone can't receive a signal in some areas. Sometimes you also use your phone as a hotspot to share Internet access with your friends, right? Similarly, this 4G LTE CPE router allows 32 users to connect to WiFi at the same time, allowing more users to connect and receive a better signal than a phone sharing hotspot. In addition, the IDU has four Lan ports and can be connected to the device through network cables, which is also a backup mode of the Internet.
3. Excellent outdoor performance and design
On the one hand, outdoor LTE CPE is waterproof, UV resistant and corrosion resistant. It can be used at -20℃~60℃ operating temperature. Therefore, it is ideal for outdoor deployment. On the other hand, there are a variety of installation methods. CPE can be mounted on Windows or walls by mounting brackets. It is also possible to attach it to the antenna mast. In addition, the signal strength is displayed through the LED indicator to facilitate users to find the best location to get a better 4G signal.
4. Support different frequency bands
Outdoor 4G CPE supports a variety of frequency bands, including LTE-FDD, LTE-TDD, 3G WCDMA, and 2G GSM network bands. Meet the needs of different frequency bands in different regions and make full use of network resources.
5. Convenient management of CPE
Start the Web browser to log in to the Web management page. You can configure and manage the CPE easily. The web management system supports Linux. Provides functions such as WebUI management, Telnet, SSH terminal system status monitoring, NTP client, synchronization between devices and the system clock network, and configuration file import and export.
6. Applicable to various application scenarios
CPE is designed to provide ISP or operator with 4G LTE outdoor wifi router to facilitate network connection, whether at home, or in enterprises and remote areas, to bring users a wonderful network experience.
All in all, an outdoor 4G CPE router is an excellent choice for connecting to the Internet in remote areas and places where the signal is weak, the wired network is unreliable, or there is a lack of reliable WiFi. It's worth deploying outdoor CPE in rural, coastal, boat, caravan, campsite and remote areas to enjoy the best network speeds and outdoor activities! It can even reduce complex cabling deployments for home networks without the need to install a wired fiber network.
