Q: Can the laptop's power adapter be used for years?: In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage to only 110V country , This feature is very useful, and some parallel notebook computers are sold only in the origin, there is no such compatible voltage design, or even only a single 110V input voltage, in our 220V mains voltage will be burned to burn.

Q: Three-phase asynchronous AC motor speed control method: Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.

Q: How does the spindle drive system of the inverter realize the positive and negative control of the main pole?: The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

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: 5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?: The speed of the AC motor is related to the frequency of the power supply. Frequency AC frequency of 50hz, asynchronous motor rated speed of about 1440 r / min, increase the frequency of course can improve the speed, naturally can exceed the rated speed, provided that the motor load to be reduced. If you need to improve more, need to replace the inverter motor, improve the motor heat dissipation characteristics.

Q: On the notebook power adapter output current and voltage issues: This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!

Q: Who knows how the frequency converter works: Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.

Q: ASUS and dell notebook power adapter can be universal?: One, not necessarily interchangeable. Need to compare the two adapter specifications to determine: 1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute. 2, however, some foreign imports of products using 110V AC products, be careful to see clearly. 3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter; Second, for example: 1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W; 2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.

Q: Which machines are used for the frequency converter: Frequency converter is widely used in the speed regulation of AC motor.Varameter speed 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, air conditioning and other fields.

Q: I power adapter output current 3.25A for a 4.5A, can you use it: Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook
