Challenges and effective countermeasures of CO2 emission rate driven by motor
According to oica (World Automobile Industry International Association), climate change caused by human activities may be the biggest challenge facing human society in the 21st century, and CO2 is a main by-product. CO2 is not the only factor affecting climate change, but it allows all sectors of society and all walks of life to do […]
Read the rated data of frequency converter
What are the rated data of the frequency converter? 1. Input side data (1) Rated voltage the rated voltage of medium and small capacity frequency converters in China is mostly AC 380V, three-phase; (2) The rated frequency is 50Hz in China. 2. Output side data (1) Rated output voltage because the output voltage of the […]
Can the frequency converter be connected to the lower end of the leakage switch?
Can the frequency converter be connected to the lower end of the leakage switch? Yes, but use a larger one with special specifications. The frequency converter outputs high-order harmonics, and the leakage current is larger than the conventional one, so the conventional leakage switch is easy to trip, and the leakage switch with large specification […]
What is the difference between industrial control computer and computer
The working principle of industrial computer is the same as that of the computer in everyone’s mouth (i.e. ordinary computer), but in practical application, the two cannot replace each other. First, understand what is an ordinary computer and what is an industrial computer? Computer, commonly known as computer, is a modern electronic computing machine for […]
What is the structure of industrial control computer? Can it be used as a computer
At present, the industrial computer market is booming, and the application scenarios of small industrial computers are very diverse. Some customers asked the customer service of our factory: can our industrial control function be used as a computer? The answer is yes. Industrial computers can be used as computers. Industrial computer, also known as industrial […]
Five challenges of smart factory to solve
With the continuous growth of edge data, connectivity and processing capacity, the industrial Internet of things (iiot) becomes more and more accessible. However, successful adoption of many products is still out of reach: two of every three companies piloting digital manufacturing solutions cannot be promoted on a large scale. Why are few companies able to […]
