Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter: but the use of the inverter is based on changes in the load by changing the frequency of power into the motor at any time speed control, you can achieve a smooth and accurate stepless speed control is Now widely used in a speed control method, especially for the load often change or often in the light load operation of the motor.

Q:The laptop power adapter is burned: You this situation or the first adapter to try, it is likely that the adapter power shortage. If you change the adapter or so, then your problem is big, there may be your laptop to protect the isolation circuit and the charging circuit is a problem, in the insurance repair is free, if the insurance, and to be afraid of a little fear Small expensive, the adapter to buy a cottage on the line, as long as tens of dollars.

Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?: The frequency changer mainly consists of rectifying (alternating current direct current), filtering, re-rectifying (direct current alternating current), braking unit, driving unit, detecting unit micro-processing unit and so on. Motor asynchronous speed expression bit: N = 60 f (1-s) / p (1) Where n --- the speed of asynchronous motor; f --- the frequency of asynchronous motor; s --- motor slip; p --- motor pole pairs. From the formula (1) we can see that the output speed of the motor is related to the input power frequency, slip rate and the number of pole pairs of the motor. Therefore, the direct speed regulation mode of AC motor mainly has variable speed (adjustment P), rotor Resistance speed control or cascade speed or internal feedback motor (adjust s) and frequency control (adjust f) and so on. And we now use the most widely used is the frequency control, from the speed n is proportional to the frequency f, as long as the change in frequency f can change the motor speed, when the frequency f in the range of 0 ~ 50Hz, the motor speed adjustment range is very width. The inverter is to change the motor power frequency to achieve speed adjustment, is an ideal high efficiency, high performance speed control means.

Q:Notebook plug in the power adapter lights, but can not open the machine: This is a contradictory problem: First, the power adapter lights because the power is good, but does not mean that the computer is good; Second, can not open the machine with the power adapter is lit, it is your computer reasons. Recommendation: Check the computer hardware. Asked: But the battery can be used to start ah answer: Remove the battery plug in the adapter or put the battery installed plug in the adapter, if you can not open the machine, then it is a hardware conflict. The solution to the hardware conflict is that you try another adapter. Asked: the battery removed to die, but as long as there is a battery can answer: it shows that your adapter is bad. Asked: the more magical is plug in the adapter and the battery, the battery will not consume Answer: get you electronic city so that they give you a test. You can say to buy an adapter, and then try, you can use the words to buy, can not use the words and then think of other methods.

Q:What parts of the inverter composition: Frequency 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 and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.

Q:Delta VFD-A frequency converter motor number of poles set: The frequency parameters of the inverter motor are not set, because the inverter will automatically detect the number of pole pairs of the motor during operation, and it will not need to be set.

Q:Laptop power adapter repair how much money: Look at your warranty period had no, no contact the seller can be free for a new one. If there is no need to repair the warranty period. Now the maintenance point is too lazy to repair. Suggest you follow your computer brand with a new one Because the maintenance fee to buy a difference can not be much money and the quality is not guaranteed, a power adapter is now dozens of dollars

Q:Does the teacher know the working principle of the inverter?: At present the main inverter is Mitsubishi you can go to their domestic sales site to find a specific inverter manual has a detailed explanation Also popular said that the inverter is to change the operating frequency of some mechanical equipment control devices, such as motors, pumps, etc.

Q:ABB frequency converter and the difference between domestic frequency converter: Both the eyepiece and the objective lens are convex lenses with different focal lengths. The focal length of the convex lens of the objective lens is smaller than the focal length of the convex lens of the eyepiece.

Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter: With the electromagnetic governor can be, cheap only 50 yuan or so
