Q:Will the laptop's power adapter is not the original good?: See the adapter is suitable for notebook models to use, the following three conditions for reference: 1. The output voltage of the adapter is the same as that of the notebook. 2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.) 3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.)

Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!: And the inverter is connected to the positive and negative bk-dk electrical Han Han device,

Q:How does the variable frequency motor output torque at very low frequencies?: 50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small

Q:Acer laptop power adapter: It might be bad, you have to determine whether the adapter or adapter adapter directly change.

Q:HP laptop power adapter how to open: HP notebook power adapter for the full size of the design, you can follow the following steps to dismantle: 1, notebook computer power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence to crack. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open. 2, the power adapter on the side of the side of the white paper, with an electric knife edge along the power adapter between the gap between the cover, and then hit the electric knife with a hammer, so that the electric knife from the adapter between the upper and lower cover go with. In the different positions of the gap between the upper and lower covers of the adapter, use the tip of the electric knife to be scratched along the gap. When the upper and lower covers are first split, the depth of the tool is deep and then the upper and lower covers of the adapter are separated. 3, then open the shell of the power adapter, you can see the adapter circuit outside the package with a copper shield, with a knife to cut the shielding tape on the tape, and then use the soldering iron shield and the internal circuit board connected to the two Solder joints, you can remove the shield. 4, between the shield and the circuit board is also separated by a layer of thick plastic film, and then cut off the knife after the United States, you can see the circuit board "Lushan true"

Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole: The upper limit frequency transferred to 25HZ, the number of poles changed to 2, try to run when the motor speed test

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:380V motor addition to the inverter, but also how to change its speed?: Use the star connection to reduce the speed by changing the torque

Q:Why G120 inverter to be equipped with 4-pole motor?: I add point with the premise of the inverter is to understand the mechanical load characteristics (or process, etc.), can the parameters set.

Q:On the laptop power adapter problem: Notebook power adapter matching the principle of the principle is: the input voltage to meet the requirements of the domestic exchange is 220V; output voltage and the original with the same output current must be greater than or equal to the original adapter output current, your future output current is less than the original will appear Power from time to time unexpected shutdown caused by increased data loss, the battery charge is not easy to rush to cause the battery aging process, the other adapter long-term work will increase the heat caused by increased safety risks.
