3. Company Introduction
Certification
- Q:The laptop's power adapter is too hot to do
- Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
- 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: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: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:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
- Second, is the higher speed, parking, inertia, the motor into a generator, to the module reverse power supply, resulting in the module burned, this time, should consider adding braking resistor and braking unit.
- Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
- Can be installed by a simple float level control to achieve, the general frequency is to constant pressure, of course, start and stop is completely controlable Oh. It's good for the pump to start the speed change
- Q:Three-phase asynchronous AC motor speed control method
- Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ??range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.
- Q:How do I protect the inverter when the three-phase two-pole motor is running?
- A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
- Q:How does the variable frequency motor output torque at very low frequencies?
- 50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small
- Q:Notebook power adapter on how to look at power
- It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,
