- Q:With the inverter control fan 37Kw4 pole with what model inverter
- Control the fan: select the fan pump with 37KW or 45KW inverter.
- 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:Delta VFD-F frequency converter how to adjust the number of poles
- P148 look, this is to correspond to the number of poles of the motor, not to adjust the number of poles of the motor
- Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
- If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%
- Q:What is the difference between variable frequency motor and variable speed motor?
- Give you a formula, you can understand their speed control principle: N (speed) = 60f (frequency) divided by P (magnetic pole logarithm) According to the formula, when you want to change the motor speed, there are only two ways to change The number of pole pairs and the frequency of the power supply. Speed motor is variable pole speed, that is, in this motor has 2 to 3 sets of windings, by changing the winding connection, to change the motor pole to change the rotation speed.
- Q: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.
- Q:Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
- Check the inverter operating power factor, straight up the motor to see if it is overheating
- Q:Laptop adapter heat
- Therefore, in the design and production of switching power supply, we must choose high temperature components. Of course, be sure to control the temperature of the power supply within the allowable range of the application environment.
First, the conversion efficiency should be designed as high as possible, and secondly, to use the pressure drop is small, low loss of switching components, the third is to be thermal design, cooling area to be as large as possible, more than 100W switching power supply Should have a metal perforated shell, or add a cooling fan. The current notebook power adapter power is generally around sixty or seventy W, the use of high temperature plastic fire sealed package, the internal heat generated by the plastic shell mainly distributed out.
Therefore, the power adapter surface temperature is still quite high, the maximum temperature or even reach about 70 degrees! Think of the inside of the adapter, it is not like the fire! So, when you use the laptop, try to place the power adapter in a better place to ventilate heat, do not put books and the like on the power above. As for the kind of hot feeling, do not have to worry about is the power, not angry strange!
- Q:How to lift Yaskawa inverter base blockade?
- Unlock the base block of Yaskawa inverter:
1. If the Yaskawa inverter reported that the base blockade, we should first check the cause, parameter settings in strict accordance with the recommendations of professional engineers to set.
- Q: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
