Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
Q:Servo control system can give the inverter signal,
Servo motor driver can give the inverter signal, with analog output to control,
Q:On the notebook power adapter output current and voltage issues
This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
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:What is the number of parameters of the motor frequency of the Siemens inverter?
Different types of Siemens frequency changer pole pair parameters different. 6SE70 is p109; The following is the p109 parameter description: P109 * Motor #PolePairs 109 For the synchronous / asynchronous motor input motor pole pairs of the function parameters. If the rated frequency (P107) and rated speed (P108) change, automatic calculation This parameter, if necessary, checks and verifies this parameter. note: - for some of the pulsed encoders (P130 = 11, 12, 15, 16) The maximum number of pole pairs of P109 = 15 can be achieved - P109 must be written when the write function (P060 = 6) is implemented. - Automatic calculation of the pole pair on the motor with regenerative feedback on the rated data Number to be added. Where the function map: 360.2, 361.2, 362.2, 363.2, 364.2   MM4 series is r313, which is calculated by the input rated frequency and rated speed calculated read-only value, must be selected in the p3900 to calculate the correct value. You can also set pole pairs by p314.   S120; G110; G120; G130; G150; S150 with MM4 series.
Q:How to view the parameters of the notebook power adapter on your computer
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
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 inverter output current proportional to the output torque?
When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload
Q:Will the motor suddenly stop when the inverter is suddenly powered down?
Generally in the absence of external brake or brake case, if the power, the motor is in a free stop state, uncontrolled,will gradually slow down to 0
Q:What is the laptop power adapter? Is it the battery?
Power adapter is inserted in the plug-in power cord connected to the black, rectangular cube that thing, after the power adapter into a notebook acceptable voltage,
