FAQ

How does the spindle drive system of the inverter realize the positive and negative control of the main pole?

The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

The parameters of the inverter is 4, 6 motor can be used

The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.

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.

I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,

wo recommendations, the first, the use of vector control of the inverter, you are expected to run the frequency of about 5Hz, this time, ordinary V / F inverter output torque may be small, not necessarily meet the requirements, of course, if it is High-end imported inverter, the problem should be small, with the domestic vector inverter, the frequency can also be full torque output;

Short-term short-circuit converter DC link positive and negative will damage the inverter?

This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),

Speed regulation method of three - phase asynchronous motor

This is the two-speed motor 1 will be the UI VI WI connected to the third phase of the remaining joint empty at this time for the four 2 U2 V2 W2 connected to the other three junctions at this time for the two levels This is the angle - there are many binary speed In addition there are three-speed motor in this no longer introduced The number of variable pole pairs can be varied, but the more variable the number of logarithmic materials Like a two-speed motor with a set of windings Three-speed motor has two sets of windings So the current single-board frequency conversion speed up

Asus notebook power adapter how to open

if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price

Laptop power adapter output voltage is not the same as the current? What's the effect?

so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
