Q:Laptop power adapter aging
First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.
Q:What is the laptop adapter
1, laptop adapter, that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry said that the traditional laptop power adapter for the single-band notebook charger.
Q:The Schneider inverter reports the nlp command
Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered
Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?
Such a high speed estimated motor can not reach, to increase the gearbox Specific algorithm: n = 60f / p P is the number of pole pairs, f is the frequency. The pole pair number of the 6 pole motor is 3. F = n * p / 60 = 8000 * 3/60 = 400 Hz.
Q:The laptop's power adapter is too hot to do
Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
Q:How do I protect the inverter when the three-phase two-pole motor is running?
A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
Q:Laptop power adapter in the ring is how is it?
Inductance and capacitive shock sound In fact, any inductance and capacitance work will be shocked, but some shocks are large, and some shocks are small, the frequency is not the same, and some sounds harsh, some not harsh, and some ears can not hear the range Inside. Of course, this noise also has a certain standard, in fact, listen carefully, a lot of more power consumption of electronic equipment (tens of watts or more) have a voice. So, as you said to hear the sound is very small, sharp degree is not the same. This do not control, as long as they can endure, the general sound is not great, rest assured that good use of the performance and stability of no effect.
Q:How many types of CVT are classified?
Power transmission Power transmission is basically divided into three categories: One is the electromagnetic sliding type, it is in the asynchronous motor to install an electromagnetic slip clutch, by changing its excitation current to speed, which belongs to a more backward speed mode. Its features simple structure, low cost, easy operation and maintenance: sliding the largest, low efficiency, serious heat, not suitable for long-term load operation, it is generally only used for low-power transmission. The second class is a DC motor type, by changing the magnetic flux or change the armature voltage to achieve speed. It is characterized by large speed range, high precision, but the equipment is complex, high cost, maintenance difficulties, generally used for medium power range (dozens to hundreds of kilowatts), has been gradually replaced by AC motor. Three types of AC motor type, through the pole, voltage regulator and frequency control. The most practical application for the frequency control, that is, using a horn to obtain variable amplitude power supply, and then drive the motor speed. It is characterized by good speed performance, large range, high efficiency, can be automatically controlled, small size, wide applicable power range: mechanical characteristics in the slow speed section of constant torque, low efficiency and low efficiency is not smooth, Maintenance need professionals. In recent years, the inverter as an advanced, excellent speed device rapid development of the mechanical CVT had a certain impact.
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 maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Motor speed and frequency of the formula N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (seconds); F - power frequency (Hirsch); P - pole pairs of motor rotating magnetic fields. China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
