Q:In the official website to buy ThinkPad notebook, to the power adapter?
Hello, generally there will be a power adapter with Kazakhstan, unless there is a special note bare metal
Q:Laptop power adapter (no power supply, but indicator light)
Notebook power adapter can not charge, but the indicator light does not light the common reasons are:
1, the power adapter is broken or the connector is broken.
2, the power adapter output problem, no output or output is too low, can not give the computer charge.
3, the notebook charging interface is broken, not into the electricity charge.
4, the notebook power management circuit out of the fault, resulting in can not charge.
Q:Quartet of the TA, TC terminals have positive and negative?
This can not be said to be positive and negative, should be called the public, TA, is the common.
Q:Who knows how the inverter is calculated?
There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Three-phase AC induction motor, 4-pole speed is generally 1480 rpm, 6-pole speed was 980 rpm
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
Under normal circumstances, with 15KW inverter on it.
Q:4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
4-5.5KW inverter made about 1300 or so, the frequency conversion motor about 3000
The same power of the electromagnetic governor + motor about 4000, the price is almost
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:Can the laptop's power adapter be used for years?
Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
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.
