The Ministry of Industry and Information Technology has authorized the experiment in four cities to carry out technical solution verification and frequency test. As a major automobile production and sales country, the Chinese government has long paid great attention to the technological and industrial changes brought about by the intelligentization of automobiles, and has given various support to emerging technology products at various levels such as policies, plans and standards. In 2016, the Chinese government officially launched the ITU Global Transport Unified Frequency (WRC-19 1.12) issue. As an important component of smart cars and smart transportation, the frequency division of the vehicle's millimeter-wave radar is also closely watched by the Chinese government. A highly regarded technical field. According to WRC-19 1.12, the lead agency of the China proposal: Pang Chunlin, secretary general of the In-vehicle Information Service Industry Application Alliance (referred to as: Automobile Association), in order to better carry out the above work, on the basis of the preliminary work, the Ministry of Industry and Information Technology issued the issue Regarding the approval of the In-vehicle Information Service Industry Application Alliance to carry out the research on the frequency research and test of intelligent transportation radio technology (the Ministry of Industry and Information Technology has no letter [2016] No. 450) document, authorize the car unit to organize industrial units in Hefei City, Anhui Province, Dalian City, Liaoning Province, Jiangsu Province Taizhou City, Mianyang City, Sichuan Province carried out research and test of 77-81GHz vehicle millimeter wave radar, conducted wireless technology solution verification and frequency test, verified radar performance parameters, frequency requirements, RF parameters, radiation power, electromagnetic compatibility and other technologies. The index provides technical reference for China's vehicle ranging radar frequency planning and WRC-19 1.12 issue China proposal, and promotes the use of vehicle ranging radar in China's smart car and smart transportation industry with high efficiency, security, safety and reliability. Radar materials, components, systems and machine industry development. With the development of intelligent vehicles, the millimeter-wave radar for vehicles has long detection distance, long bandwidth, small antenna, high integration, stable detection performance, no influence on the surface shape and color of the detected object, and is not affected by large airflow. Advantages, as well as good environmental adaptability, have become an indispensable equipment in car collision warning, adaptive cruise, active safety (ADAS) and even automatic driving technology. According to relevant statistics, in 2014, the global automotive millimeter wave radar market shipments were 19 million, and it is expected to reach 72 million by 2020. The compound growth rate in the next five years is about 24%, and the total market will exceed 20 billion. yuan.
Dc gear motor, namely gear reduction motor, is based on ordinary Dc Motor, coupled with gear reduction gearbox.
The gear reducer is used to provide low speed and large torque.
At the same time, the gearbox with different deceleration ratio can provide different speed and torque.
Generally different industries, using different power dc motor, generally adopt custom parameter design pattern.
What are the four ratings of the Dc Gear Motor? The DC gear motor is often seen in our industrial production. Here Shunchang Motor gives you the knowledge of its four ratings. To talk about
precision instruments and meters,automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows,etc., wide application range
Features: gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
