Q: Motor 2 pole and 4 pole in the inverter with what set to show: There are parameters for the number of motor poles / pole pairs or the rated speed of the motor in the inverter parameters

Q: Laptop power adapter repair how much money: Different notebook power adapter models are different, the price gap is large. ? Maintenance costs to see the specific model and damage level position. Generally do not recommend maintenance, it is recommended to replace the more appropriate. If you are not covered by the warranty period, you can repair free of charge. Hands-on ability to recommend self-repair, pay maintenance department recommended. After all, once again a greater chance of damage.

Q: 6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: Such a high speed estimated motor can not reach, to increase the gearbox Specific algorithm: n = 60f / p P is the number of pole pairs, f is the frequency. The pole pair number of the 6 pole motor is 3. F = n * p / 60 = 8000 * 3/60 = 400 Hz.

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: Octopus AC Servo motor can be driven with ordinary inverter?: If it is synchronous motor, it depends on whether you choose the inverter is compatible with the synchronization machine, most of the incompatible. As you said the situation, the motor 8 pole, may be synchronous motor. Specifically, you can compare the rated speed and rated frequency to see if there is a slip rate to determine whether it is synchronous or asynchronous motor.

Q: Inverter problem: (0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.

Q: What is the principle and implementation of the inverter?: AC inverter principle. It is the first AC current will be converted into direct current, and then use the electronic components of the DC switch. AC power. General power of the larger inverter with a thyristor. And set an adjustable frequency device. The frequency in a certain range adjustable . Used to control the number of revolutions of the motor. The number of revolutions can be adjusted within a certain range. The frequency converter is widely used in the speed regulation of AC motor. Frequency control technology is an important development direction of modern power transmission technology, with power electronics Technology development, exchange 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. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.

Q: Do you need to rectify before switching?: I used to do the frequency of the words to be rectified

Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity: It depends on what type of equipment you use, the average energy-saving fan pumps, about 25-40 between; generic class is based on the frequency you use to decide, according to the frequency you use with 50 Hz Compared to energy saving.

Q: The laptop's power adapter can be used on a desktop computer: Desktop machine is called DIY it ~ is the assembly machine inside the motherboard graphics card hard drive memory What is the need for power supply every power to have a different interface
