Q:Delta VFD-A frequency converter motor number of poles set
The frequency parameters of the inverter motor are not set, because the inverter will automatically detect the number of pole pairs of the motor during operation, and it will not need to be set.
Q:What is the laptop adapter
4, the working principle: the use of unstable power supply switching power supply principle through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop computer power supply and charging; it is worth noting that: this conversion circuit, there must be protection circuit (Overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.), to prevent accidents, the protection of the laptop will not burn.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
Remember, 2001 this should be set to a negative number, set to a positive number of your speed will never be less than this value.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, but is being used in the motor replacement, you need to change the frequency conversion.
Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
According to the number of revolutions N = 60 * f (frequency) / p (pole pairs) can calculate the motor is a few poles. If the motor is 8 pole is not recommended in the inverter set to 4. will certainly affect the control accuracy.
Q:Notebook power adapter on how to look at power
then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.
Q:Lenovo laptop power adapter side of the feet which is positive
Very simple, look carefully on the power there is a symbol on the map (relatively small, carefully looking for all the regular power above the standard), as I shown below is the positive external, most of the power is like this , If the sign on the icon is anti, that is connected to the center of the black point is negative, that is negative inside the positive. This figure is also very intuitive.
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:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
can! The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.
Q:Can the laptop power adapter be generic?
Not necessarily, the laptop power adapter has two interfaces for input and output. 1. Input interface is connected to the power outlet, generally divided into two holes and three holes, as well as round mouth and flat mouth of the points; 2. Output interface is connected to the computer side, size, length, diameter, diameter, the pin may have differences, common are: diameter 2.5MM, ordinary mouth, mainstream interface; OD 1.7MM, small mouth; MM, big mouth with a needle, round mouth with a needle and so on. 3. Different voltage, different brands of laptop power adapter voltage is not the same 4. Current is different, different brands of notebook computer power adapter current is not the same In summary, the laptop power adapter between the different types, basically not common
