Q: Laptop adapter: The first of the power to be large, not recommended to use the second to replace the other 90W adapter size are similar, but if the computer is not installed when the battery, 65W can also be used, as long as the interface on the Oh

Q: A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole: First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!

Q: What are the types of power adapter used in notebooks?: The regulator wants the laptop adapter to not waste energy or add harmonics to the electricity lines. The first factor is that the adapter should plug the plug without any load, and it should be as small as possible to absorb power (standby). People are accustomed to the laptop adapter inserted in the socket, but not connected to the computer, the request can prevent the loss of this situation. The second factor is the recent requirement that it requires a specific average power efficiency at different load conditions (25%, 50%, 75%, and 100%) and is implemented by the global regulatory agencies in order to facilitate compliance with the specification And reduce overhead costs. Finally, the European and Japanese mandated reduction harmonics requirements have been applied to laptop power adapters because they have exceeded these standard specifications for the 75 W input power threshold. In a sense, the mobile / universal features of the laptop adapter make it the first mass production power product subject to the IEC1000-3-2 specification.

Q: Is the speed of the motor controlled?: Slip motor is composed of ordinary squirrel cage asynchronous motor, electromagnetic slip clutch and electrical control device composed of three parts. Asynchronous motor, the stepper motor is used as the prime mover, and when it rotates, the armature of the clutch is rotated together. The electric control device is a device that provides the excitation current of the slip clutch excitation coil. Electromagnetic slip clutch, which includes armature, magnetic pole and excitation coil three parts.

Q: What is the working principle of high voltage electrodes and frequency converters?: High-voltage inverter is the input power supply voltage above 3KV high-power inverter, the main voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and other voltage levels of high-voltage high-power inverter High voltage inverter from high - low - high; low - high; high - high points.

Q: Variable frequency pump pressure in the very low flow instability, why?: . If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.

Q: The Schneider inverter reports the nlp command: Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered

Q: Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?: There is no power adapter is not the number of clocks that the current output of the current frequency is the number of security in the case of the maximum number of output support the specific output current is the number of security is based on the current power consumption of the computer But please note that the power adapter output voltage must be consistent with the original agreement is now generally 20V

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: Jd1a-40 motor speed controller and how to connect the motor: First, variable pole alignment speed method This method of speed control is to change the stator winding winding red method to change the cage motor stator pole pairs to reach the speed control target, the characteristics are as follows: This method is suitable for production machinery which does not need stepless speed regulation, such as metal cutting machine, lift, lifting equipment, fan, water pump and so on. Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing the speed of its synchronous speed control method. Frequency converter system can be divided into exchange - DC - exchange converter and exchange - exchange inverter two categories, most of the current domestic use of cross - straight - cross frequency converter. Its characteristics: This method is suitable for the requirements of high precision, better speed performance.
