Q:B2b frequency how to speed
can be seen from the formula: frequency f changes, the speed will follow the change. 2) When the motor connected to the public grid, you can use the inverter (2) When the motor is connected to a single motor, you can change the output frequency of the generator directly to change the output frequency of the generator. Change the frequency of the power supply to the motor to change the speed of the motor.
Q:Can different brands of laptop power adapters be generic?
Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.
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:How do I select a drive? Which brand is better
   4, when the inverter is used to control several motors in parallel, be sure to consider the inverter to the motor cable length of the sum of the inverter in the allowable range. If you exceed the specified value, to enlarge one or two steps to select the inverter. In addition, in this case, the inverter control mode can only be V / F control mode, and the inverter can not protect the motor over-current, overload protection, this time in each motor on the fuse to achieve protection.     5, for some special applications, such as high ambient temperature, high switching frequency, high altitude, etc., this time will cause the inverter derating, the inverter need to enlarge a file selection.     6, the use of inverter control high-speed motor, due to high-speed motor reactance small, high harmonics also increase the output current value. Therefore, when selecting a frequency converter for a high-speed motor, it should be slightly larger than the inverter of an ordinary motor.     7, the inverter for the variable pole motor, should pay full attention to select the inverter capacity, so that the maximum rated current in the inverter rated output current below. In addition, in the operation of the number of pole conversion, you should first stop the motor work, otherwise it will cause the motor idling, bad will cause damage to the inverter.
Q:What is the output voltage of the laptop power adapter?
Generally have 19V of the common friends, I was 19V
Q:On the laptop power adapter problem
Notebook power on the two specifications, one is 65W, one is 40W, 65W power supply is a discrete graphics notebook, 40W is integrated graphics notebook. Just connected to the use of power, then there is no problem. Just if you laptop battery with the light of the words, plug in the power can not be the same as with the 65W, immediately you can use the boot. Because the current is low, the charging speed is relatively slow. The other will not have any effect
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:Quartet of the TA, TC terminals have positive and negative?
There is no positive and negative, this is the relay output
Q:Laptop power adapter current is not the same alternative?
The adapter is the voltage source, the actual output current depends on the size of the load resistance,
Q:Can the laptop's power adapter be used for years?
In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage to only 110V country , This feature is very useful, and some parallel notebook computers are sold only in the origin, there is no such compatible voltage design, or even only a single 110V input voltage, in our 220V mains voltage will be burned to burn.
