What is the difference between FG signal and RD signal of Sanyo Computer fan

What is the difference between FG signal and RD signal of Sanyo Computer fan FG signal (also known as flywheel signal) and RD signal (also known as rotor positioning signal) are two types of signals related to motor operation, which have different characteristics and purposes. The FG signal is a signal generated by the flywheel of the motor, which is usually a pulse signal with a frequency proportional to the speed of the motor. This signal can be used to measure the speed of the motor by monitoring the frequency of the FG signal. Usually expressed in revolutions per minute (RPM). The RD signal is the signal generated by the Rotary Position Sensor. The main function of this signal is to detect the rotor position of the motor, usually achieved through the use of Hall sensors or photoelectric sensors. The frequency of the RD signal is usually a multiple of the number of pole pairs of the rotor, which can be used to determine the rotor position and operating status of the motor. To use the FG signal to achieve a locked rotor alarm, the following steps can be taken: 1. Obtain FG signal: Ensure correct connection to the flywheel of the motor and obtain FG signal. Sensors or interface circuits can be used to detect and extract FG signals. 2. Set speed threshold: according to the Design specification or application requirements of the motor, determine a suitable speed threshold, which can be used to judge whether the motor is locked. 3. Monitoring speed: Convert the real-time measurement of FG signal frequency into speed value, and use a counter or timer to measure the pulse number or pulse interval time of FG signal, and convert it into speed value. 4. Compare speed: Compare the measured speed value with the set speed threshold. If the measured speed value is lower than the set threshold, it indicates that the motor may be in a locked rotor state. 5. Trigger alarm: Once a locked rotor situation is detected, a locked rotor alarm can be triggered. The specific method of alarm can be selected according to the application requirements, such as issuing an audible alarm, sending alarm notifications, etc. It should be noted that using FG signals for locked rotor alarm is not the only method, and other sensors or technologies can be combined to increase the reliability and accuracy of detection. In addition, the specific implementation methods and parameter settings may vary depending on factors such as motor type and application environment. It is recommended to adjust and optimize according to the actual situation.

Requirements for voltage, amplitude and frequency of SanAce Computer fan pwm speed regulation drive

Requirements for voltage, amplitude and frequency of SanAce Computer fan pwm speed regulation drive In practical applications, efficient heat dissipation systems are crucial for the reliability and performance of equipment. As one of the core components of the cooling system, the Computer fan undertakes the important task of removing a large amount of heat generated by the equipment. Its stability and reliability are critical to the normal operation of the entire system. In order to realize the precise control of Computer fan, PWM (Pulse Width Modulation) technology is widely used in the speed control drive circuit. However, the PWM speed regulating driving voltage, amplitude and frequency of the Computer fan need to meet certain requirements to ensure its normal operation and stability. These requirements may vary depending on different fan models, manufacturers, and applications. Here are some common requirements: 1. Drive voltage The driving voltage of Computer fan is one of the key factors to ensure its normal operation. Generally, the driving voltage of Computer fan is DC voltage, and the common range is 12V; But other voltages, such as 5V or 24V, can also be used, depending on the specifications and design requirements of the fan. When using PWM speed control drive, the stability and accuracy of the voltage are very important to ensure that the fan can operate normally and adjust the speed as needed. If the voltage is too low, the fan may not start normally or the speed may be too slow; If the voltage is too high, it may cause damage to the fan circuit and motor. Therefore, before selecting the PWM speed control drive voltage, it is necessary to carefully study the fan specification sheet or manufacturer's manual to ensure that the selected drive voltage range is suitable for the target fan. 2. Amplitude The amplitude of PWM speed regulation refers to the voltage difference between high and low levels. Generally speaking, the common PWM amplitude is 3.3 volts (V) or 5 volts (V), but the specific requirements depend on the specifications and design of the fan. When selecting a wide value, it is necessary to ensure that the PWM signal can be correctly understood and responded to by the fan. You can refer to the specifications of the fan or the technical information provided by the manufacturer to understand the PWM bandwidth requirements for using the fan. 3. Frequency The frequency of PWM speed control drive voltage refers to the periodic repetition frequency of pulse signals. The frequency selection should be determined based on the characteristics and application requirements of the fan. The common PWM frequency range is from tens of Hertz to hundreds of Hertz. A lower frequency may cause a delay in the response time of the fan speed, while a higher PWM frequency can provide smoother and more accurate speed adjustment, but it also increases the electromagnetic interference of the system. Therefore, when selecting PWM frequency, it is necessary to comprehensively consider the accuracy of speed regulation and the Electromagnetic compatibility of the system. The PWM speed regulating driving voltage, amplitude and frequency of the Computer fan need to be selected and adjusted according to the specifications and design requirements of the fan to ensure that the fan can work normally and stably, and can provide the required speed adjustment range and accuracy.

The reason why the cooling fan suddenly does not turn

The reason why the cooling fan suddenly does not turn 1. Power failure: If the power supply of the fan fails, such as disconnecting the power cord or loosening the power plug, it can cause the current to not be transmitted normally, resulting in the fan stopping running. 2. Low temperature: Some heat dissipation windbreakers have temperature protection function. When the temperature is too low, the fan will automatically stop working to avoid excessive cooling. This usually occurs in low-temperature environments, such as winter or air-conditioned environments. 3. Lubricating oil drying up: It is possible that the lubricating oil has dried up. Try to rotate the fan with your hand. If there is any sign of slight movement or if you feel that the rotation resistance is very high, it indicates that the fan is not a problem. However, if the lubricating oil has dried up, remove the fan. Generally, there is a sticker on the opposite side, and when you remove it, you can see the fan shaft. Add some lubricating oil such as engine oil, Then rotate the fan a few more times by hand, feeling that there is no resistance or the resistance is very small, and reinstalling it can almost solve the problem. 4. The speed has not reached the normal speed required for operation 5. Fan controller failure: Some advanced cooling fans are equipped with controllers. If the controller fails, such as burning out the circuit board or damaging circuit components, it can cause the fan to stop running. 6. Overload protection: When the cooling fan is working, if the load is too large, such as in case of overclocking or overvoltage, the fan power current may exceed the rated value, which will trigger overload protection and the fan will stop rotating to protect the circuit. 7. Not paying attention to cleaning and maintenance: Due to the environment where the cooling fan is located being dusty or used for a long time, and we do not clean it very much, it is very likely that the power supply of the cooling fan cannot rotate due to excessive dust. This is mainly because as the dust increases, the internal heat accumulation of the cooling fan also increases, leading to poor internal heat dissipation of the power supply and unstable power supply, The fan speed is also unstable, so it is important to maintain the cooling fan and regularly clean it. There are many reasons why the cooling fan does not turn. It may be an external cause of the cooling fan, or it may be a malfunction or damage caused by the cooling fan during operation. If the cooling fan suddenly does not turn, it is recommended to check whether the power connection is normal, whether the power supply provides sufficient voltage and current, and whether the fan has overload protection functions. If these are all correct, it may be necessary to check whether the fan itself has mechanical or controller faults, and further maintenance or replacement is needed. Before carrying out any repairs or replacements, it is recommended to refer to the relevant fan manual or consult a professional.

How is the Sanyo cooling fan protected from corrosion?

How is the Sanyo cooling fan protected from corrosion? The key to using heat dissipation fans in industrial production is to perform tasks such as heat removal, cooling, and ash removal for large and medium-sized production line equipment. The natural environment of general industrial production is very complex, and in order to increase its service life, cooling fans must be treated with certain measures, such as the most common anti-corrosion. For example, if the cooling fan experiences oil leakage and oil spillage, today we will provide a detailed introduction to how the cooling fan can prevent corrosion for everyone 1、 Surface treatment of heat dissipation fans: The surface prevention and treatment of heat dissipation fans are generally carried out through methods such as galvanizing, chromium plating, chemical plating, etc. This method is reasonable in many natural environments, but for rotating parts, it must be carefully selected. As the substrate material and coating are two different materials, their linear expansion coefficient is different, which will cause different deformation variables during the elastic deformation of the rotating part, leading to many micro cracks and accelerating the occurrence of corrosion. Therefore, people must choose appropriate materials and processes based on the specific application natural environment. 2、 Cooling fan development: The development of cooling fans is a manifestation of its key technology, which interferes with the fan's service cycle and ensures the safety factor of the fan's application. The architectural design of the cooling fan is most likely to accelerate the development of corrosion. The drawbacks are stress tendency and gap environment. Sometimes, although metal materials are immersed in solvents, the corrosion rate is relatively low; However, the generation of gaps, due to changes in the chemical and electrochemical conditions of the internal solvents, will result in severe crevice corrosion, which requires careful design. 3、 Raw materials for heat dissipation fans: There are certain differences in the raw materials used for different heat dissipation fans, and the actual corrosion resistance effect is also different. After selecting the cooling fan model, based on the corrosion resistance of different raw materials in different ring mirrors, key application environments, working compressive strength, and many other factors, the compressive strength of the raw materials for the parts is determined from a fundamental analysis. From the perspective of raw materials themselves, they are considered safe for the overall target raw materials.
