Q:Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion The device has also been very widely used.
Q:Servo control system can give the inverter signal,
but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.
Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad
Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
can. Re-enter the new motor parameters in the drive.Inverter motor power to 4KW, speed 980 can!
Q:On the notebook power adapter output current and voltage issues
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
Q:What are the types of power adapter used in notebooks?
The regulator wants the laptop adapter to not waste energy or add harmonics to the electricity lines. The first factor is that the adapter should plug the plug without any load, and it should be as small as possible to absorb power (standby). People are accustomed to the laptop adapter inserted in the socket, but not connected to the computer, the request can prevent the loss of this situation. The second factor is the recent requirement that it requires a specific average power efficiency at different load conditions (25%, 50%, 75%, and 100%) and is implemented by the global regulatory agencies in order to facilitate compliance with the specification And reduce overhead costs. Finally, the European and Japanese mandated reduction harmonics requirements have been applied to laptop power adapters because they have exceeded these standard specifications for the 75 W input power threshold. In a sense, the mobile / universal features of the laptop adapter make it the first mass production power product subject to the IEC1000-3-2 specification.
Q:Laptop adapter heat
In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
First, the frequency control: the use of frequency converter to change the frequency of the motor stator power supply, thus changing its synchronous speed control method for all motors, which is the most advanced, the most widely used speed control method.
