Q:Laptop power adapter aging
This is not much relationship with the adapter, is your laptop internal hardware overheating, leading to self-protection open and shut down.
Q:Laptop power adapter bad what is the phenomenon?
If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,
Q:The emitter E of the inverter inverter module and the AC output U are not directly connected together
Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Is the inverter must be. Do not know you are also a generic vector. If it is common to directly on the instructions on the motor logarithmic change 6 pole, turn the number changed to 980 on the line. Vector, then change the number of 980 and then learn from the line on the line.
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.
Q:Laptop power adapter leakage
You feel, or do not feel is to take the amount of pen? If the feeling after it, then for a, if the amount of pen, then hand touched, it should not be bright. That is a induction, is Virtual electricity, it does not matter.
Q:Laptop power adapter in the ring is how is it?
Notebook power adapter generally use the switch circuit, the output 12V DC power supply, as the notebook DC / DC converter circuit power supply; In the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire);
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
To 400HZ, so high frequency you tried it? I only tried 80HZ, if you tried, please tell me some of the high frequency of the actual situation will produce some changes in the motor,
Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
11KW the following can be brought, the inverter rectifier module may be broken,
