Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Change 6 will only be slower, the fan is no longer role. The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.
Q:65w adapter and 90w laptop power adapter What is the difference?
According to ibm specification T6 x6 r6 series power supply is compatible The difference is x6 this thin model with 65 The official explanation is (original English), in the 90w models using 65w machine may be in high power consumption, can not meet the system requirements. That is, while the side of the charge side of the use, it is possible that the computer can not run at full speed. In fact, the use of and there is no problem, but also little, at least the machine is no harm. For psychological factors, you can buy a 90w, Taobao fake a lot, you are not professional or to Jingdong to buy, about 250 yuan, although it is more expensive, really is the original.
Q:ASUS power adapter Acer can use it
3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) If it is for DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. Acer and Asus are not yet available. It is said that the market is also very popular universal adapter, a friend bought a LVSUN brand universal adapter LS-PAB90-BC10, with eight joints. Adapter has a liquid crystal display, you can also automatically switch the voltage, very smart, with more than a year, has also been used.
Q:Pump frequency converter instantaneous restart and restart the problem
Inverter speed: Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values ​​every 25μs. The torque comparator and flux comparator compare the actual values ​​of torque and flux with the reference values ​​for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.
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
Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
The number of poles of the motor and the inverter is not very different, the difference is the motor speed is different
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:Lenovo g450 laptop power adapter specifications is what?
Lenovo g450 laptop power adapter specifications is what? Wrqwgp520 | viewed 4426 times Recommended at 2016-05-26 08:52:41 Best answer Lenovo Lenovo 19V4.74A G450 G470 Laptop AC Adapter: 【Power supply technical parameters】 1. Input voltage: AC100-240V.50-60Hz.1.5A 2. Output voltage: 19V 3. Output current: 4.74A 4. Work efficiency:> 85% 5. Output power: 90W 6: Input interface: Plum triangular interface 7: Output interface: 5.5 * 2.5
Q:Laptop warranty period is not over, the power adapter is broken, repair money?
Have to admit that the emergence of Thinkpad x100e, will hit the Internet completely decent, this product is not the name of the Internet, but "ultra-portable notebook", which also shows the x100e relentless and the Internet is willing to belong to similar products. It can be said, x100e is turned out in 2010 turned out professional jet client!
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
that is, the load is very heavy; caused by over-current burning inverter
