Q:My Lenovo v450 laptop power adapter should be bad how to match?
Hello, this is not recommended to go online to buy. The original is too expensive, generally with the domestic voltage instability may occur, so I suggest you go to the computer city to buy. Generally good quality, to about 120. The The As for the model, you can look at the output power, or you take your bad adapter to go, people see a look. The The The You can use a few years no problem, power adapter this kind of thing, online to buy the replacement is not convenient. The Hope to help you
Q:What is the laptop adapter
3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).
Q:Can the four motors be tuned to 2900 rpm?
You have to look at what is the load, and look at the motor bearing can not bear 2900 turn, if the line, then under normal circumstances are possible. Only to the speed up to the motor rated speed above, the motor output torque is reduced.
Q:Why the notebook power adapter can not be universal
Third, the current is different Different brands of laptop power adapter current is not the same, for example: under normal circumstances IBM is 4.5A, Dell is 3.34A, Hp is 2.7A, Sony is 4.1A and so on. In fact, the same brand of laptop power adapter voltage and current are not the same. So, even if the same brand of notebook computers channeling with power adapter to confirm the voltage and current specifications.
Q:Is the inverter output current proportional to the output torque?
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
Q:How do I select a drive? Which brand is better
 Ampang letter company can provide different types of inverter, the user can according to their actual process requirements and the use of occasions to choose different types of frequency converter. When selecting the inverter, note the following precautions:     1, according to the load characteristics of the inverter, such as the load for the constant torque load; fan, pump load should be selected AM300 inverter.     2, select the inverter should be the actual motor current value as the basis for selection of the inverter, the motor rated power can only be used as a reference. Also should take full account of the output of the inverter contains high harmonics, will cause the motor power factor and efficiency will be bad. Therefore, with the inverter to the motor power supply and power grid power supply compared to the motor current increased by 10% and the temperature increase of about 20%. Therefore, in the choice of motor and inverter, should take into account the situation, the appropriate margin to prevent the temperature rise is too high, affecting the motor life.     3, the inverter to long cable operation, this time should take measures to suppress the long cable to the ground coupling capacitor, to avoid the inverter output is not enough. So the inverter should be amplified or selected to install the output reactor at the output of the inverter.
Q:Is it possible to use a different laptop's power adapter?
It is recommended to use the original comes with the adapter, different adapter output voltage is not the same
Q:Laptop power adapter in the ring is how is it?
Notebook power adapter generally use the switch circuit, the output 12V DC power supply, as the notebook DC / DC converter circuit power supply; In the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire);
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:30 kW 6 pole frequency motor torque is how much
30 kW 6 pole frequency motor torque is how much 860. 1, the motor torque calculation Motor "torque", the unit is N? M (beef) 2, the formula is T = 9549 * P / n. 3, P is the motor rated (output) power unit is kilowatts (KW) The denominator is the rated speed n units are per minute (r / min) P and n can be found directly from the motor nameplate.
