When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.

Manual testing can take up most of a technician's time. The solution to the problem can be auto-mated testing using signature analysis systems. However, even here you can face the problem of lack of documentation for the board. This problem is not acute if there is documentation or if we are talking about new boards, the documentation for which is publicly available. However, what if the boards have been produced for a long time, and the documentation has been lost? In this case, intelligent recognition systems can help, which will allow you to identify component pins without documentation for the board. In this article we will show you how easy and fast it is possible thanks to our EyePoint p10 and EyePoint S2 systems, using the STM32F429 board as an example.

Refrigerators are very common in our daily life. Most people know how to use refrigerators, but they do not know the relevant knowledge. Sometimes the refrigerator is out of order, but users do not know how to solve it. Today's home appliances, refrigerators, and air conditioners all have compressors, which are their core components. Once the compressor fails, these appliances will strike! To test the quality of the compressor, you need to master some basic knowledge, such as the judgment of the quality of the hermetic compressor? Today, we will let you understand how to test the refrigerator compressor.

The CT (Current Transformer) is a component used to detect current signals, which is based on a transformer. Compared with Hall devices, it is cheaper, but due to the exciting current, the detected current will be wrong in principle. But for the applications that do not require high-accuracy current, a current transformer can play an important role. This article will introduce the use, the model, the method to avoid saturating and its selection.

When speaking of air conditioners, everyone is familiar with them. Especially in the hot summer, we would not know how to live without it. But when it comes to refrigeration compressors, many consumers are not particularly clear. In fact, the refrigeration compressor is an important part of air conditioners and refrigerators, and its performance and quality directly determine the cooling effect of them. The following is an introduction to the types of refrigeration compressors.
