- Q: Is the laptop power adapter high temperature normal? Is there anything else?
- Normal, my power adapter is also very hot, generally ignore
- Q: 380V motor addition to the inverter, but also how to change its speed?
- 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency
- Q: Will the motor suddenly stop when the inverter is suddenly powered down?
- Generally in the absence of external brake or brake case, if the power, the motor is in a free stop state, uncontrolled,will gradually slow down to 0
- Q: Laptop power adapter bad what is the phenomenon?
- If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,
- Q: Laptop adapter heat
- In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!
- Q: What is the frequency of `30 points
- Frequency is to change the frequency ah, see what you are variable frequency equipment.
- 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: Yasukawa inverter reported bb code that is the reason why the base blockade?
- This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad
- Q: On the laptop power adapter problem
- Can be simply calculated; 19 * 4.74 = 90.06 90W 19 * 3.42 = 64.98 65W Obviously, the second is a virtual standard, can not be used It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable. The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common. My notebook is dell original 4.62A, when playing the game are very hot.
- Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?
- ?Fourth, the electromagnetic speed: electromagnetic speed motor by the cage motor, electromagnetic slip clutch and DC excitation power. DC excitation power is small, usually by single-phase half-wave or full-wave thyristor rectifier composition, change the thyristor conduction angle, you can change the size of the excitation current.
