Q:How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?
Power, voltage, frequency, and you can use torque sensors to measure torque
Q:How to choose a power adapter
There are several principles for replacing the power adapter. 1. The voltage is the same or similar. Your computer's nominal input voltage is 16V, and the following adapter's rated output voltage is 20V, the difference is large, can not be replaced, may damage the computer. 2. The plug has the same polarity. Your notebook marked on the polarity of the mark is inside and outside the negative, that the adapter I really can not see what is the polarity of the label, you take a closer look if the symbols and notes on the notebook is not the same, it is absolutely not. 3. The rated output current of the power adapter can not be less than the rated input current of the computer. Your computer marked the maximum input current is 3.36A, then you buy the power adapter when you want to buy the output current greater than or equal to 3.36A, the bigger the better, but the greater the output current that the greater the rated power, too much Waste, and very cumbersome, generally slightly larger than on the line, leaving some margin.
Q:Laptop power adapter (no power supply, but indicator light)
There may be reasons for the power adapter, there may be a computer can not identify the power supply is battery-powered or AC power. These are just speculated by your phenomenon, if you are better in the warranty period to the customer service test, so the best
Q:Does the inverter set the number of poles to match the number of poles of the motor?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
Q:What is the characteristic of the variable pole speed method?
Edit this paragraph speed method First, variable pole alignment speed method This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of 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. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.
Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Hi, the inverter control is no problem. You need to select the inverter by the load characteristics of the centrifugal pump, consider: Centrifugal pump rated working current, overload capacity, parking whether there is emergency stop request. I used the inverter to control the horizontal centrifuge some time ago.
Q:The notebook power adapter flashes
The problem is very simple Well, used to know all the notebook Kazakhstan, the adapter has a light above, if it is lit that is the problem of the notebook, the other side of the notebook above also have a power indicator, the notebook above prompted the red, but not Rushed, that is, the problem of the notebook, the computer problem, you directly on the factory is finished, if the insurance, and casually find a place to repair a Kazakhstan, 50-80 yuan if the adapter is bad, buy a generic You can, but also more than 50 points, the last time I bought a bad 58 yuan, ASUS GM, to help people in the end, to give you a shop to buy the adapter, you ask the owner of Kazakhstan to get,
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q:Inverter alarm a043, how is it
Check processing: Check if the cable is disconnected. Check the tachometer to shield the ground. The shield is not only on the motor side, but also on the inverter side The cable of the pulse encoder should not be disconnected. The pulse encoder cable can not be laid together with the power loop cable. Use only the recommended pulse encoder.
Q:What is the laptop power adapter? Is it the battery?
so that the book can be normal operation, or else you think the notebook is 220V Is the voltage at work?
