Q:B2b frequency how to speed
AC motor speed control methods are four: frequency, transformer, variable pole and winding motor to change the rotor loop resistance of the speed control method. Its source is based on the motor speed formula: n = (1-s) * 60f / p where: n --- motor speed s --- motor slip f --- power frequency p --- motor pole Logarithm
Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
Two questions: 1, the inverter output waveform is not a standard sine wave, with the ordinary calorimeter measured value is completely not allowed. The output current of the inverter is the same.
Q:How to lift Yaskawa inverter base blockade?
2. If you can not solve the problem, be sure to seek the help of professionals.   3. If the base of the frequency converter blocks the input signal. While the base blockade, the inverter power tube is all closed, this one is mainly to protect the power tube. So the external input signal once resolved, the base block is automatically removed.
Q:Fuji inverter motor set the number of poles will not have any effect?
The number of poles is not the same as the speed is not the same mistake machine can not work or motor coil burned
Q:What parts of the inverter composition
Frequency control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
P = UI, that is, power = voltage × current. That is only the voltage of the motor will be faster, so the higher the speed the greater the power
Q:The relationship between the power supply of the notebook and the battery
1, when the notebook battery is fully charged, and connected to the power adapter, usually by the adapter directly to the host power supply, this time the battery is idle, the adapter power supply without battery conversion.
Q:How to disassemble the notebook power adapter
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: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:How to view your own laptop power adapter is how much tile?
1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
