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: 2, upstairs brothers to answer the correct, the basic frequency is the following constant speed torque control, load changes little, the current change is not large.

Q: Inverter signal line analog 4-20mA connection positive and negative can be reversed?: Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.

Q: What is the laptop adapter: 1, laptop adapter, that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry said that the traditional laptop power adapter for the single-band notebook charger.

Q: Laptop power adapter leakage: In fact, the adapter does not matter fake real goods, brand machine adapter are also purchased. According to my point of view, or I choose the words: casually buy one can, dozens of dollars on the line. In fact, the adapter is also worth tens of dollars, selling a few hundred dollars are also almost the same thing. Adapter is a small switching power supply, 100W or so, the value of that price.

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: Laptop power adapter output voltage is not the same as the current? What's the effect?: so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply

Q: What are the AC motor speed control methods? What are the characteristics of each: 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency

Q: Do not the laptop directly connected to the power adapter?: "Notebook do not power adapter", can only use the internal lithium battery power supply work. It can not directly use 220V AC power supply for it. 1, because the notebook product design power supply standard, is to use the matching power adapter power supply. That is, the power adapter will 220V civilian AC, rectifier filter, and then converted to low-voltage 19V DC, for the notebook to provide power supply;

Q: How do I select a drive? Which brand is better: ??8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside. ????9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value. ????10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.

Q: Motor a speed, the inverter will burn what is going on, the inverter is a large yuan: Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
