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 use. But in the inverter "motor parameters" to be some changes. Such as the number of poles, rated current.
Q: Laptop computer about electricity no electricity, is the power adapter problem?
To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
Q: Is the inverter output current proportional to the output torque?
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
Q: Laptop power adapter aging
First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.
Q: Laptop power adapter (no power supply, but indicator light)
Notebook power adapter can not charge, but the indicator light does not light the common reasons are: 1, the power adapter is broken or the connector is broken. 2, the power adapter output problem, no output or output is too low, can not give the computer charge. 3, the notebook charging interface is broken, not into the electricity charge. 4, the notebook power management circuit out of the fault, resulting in can not charge.
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: Is the laptop power adapter long-haul?
Can, rarely say there is a power adapter without power and failure, my notebook 5 years, never pull the power adapter plug, never power, there is no problem. Of course, save electricity and care from the point of view, it is recommended to pull the best, because the adapter is still in the working state.
Q: I power adapter output current 3.25A for a 4.5A, can you use it
Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook
Q: 22kw.2 pole fan can use Fuji inverter?
according to the rated name of the fan brand and the inverter rated current control, select the current value match, or slightly larger The
Q: 400w 6-pole motor should be equipped with much of the inverter?
Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on
