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:Do not the laptop directly connected to the power adapter?: "Notebook do not power adapter", can only use the internal lithium battery power supply work. It can not directly use 220V AC power supply for it. 1, because the notebook product design power supply standard, is to use the matching power adapter power supply. That is, the power adapter will 220V civilian AC, rectifier filter, and then converted to low-voltage 19V DC, for the notebook to provide power supply;

Q:There is no inverter comes with simple PLC programming function: The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.

Q:What is the output voltage of the laptop power adapter?: 16V to 20V, different brands may be different, 19V, 20V more.

Q:Laptop power adapter output voltage is not the same as the current? What's the effect?: In the case of other conditions (rated output voltage, plug polarity, etc.) the same circumstances, the rated output current greater power adapter, can replace the rated output current is relatively small power adapter, which is not adversely affected. If the power adapter with a relatively small rated current is used instead of a relatively large power adapter with a rated output current, the power adapter will be "overloaded" and may cause damage to the power adapter.

Q:What is the laptop power adapter? Is it the battery?: so that the book can be normal operation, or else you think the notebook is 220V Is the voltage at work?

Q:Short-term short-circuit converter DC link positive and negative will damage the inverter?: the switch signal Is the fan running up after the speed line is low, this can be shorted. Pulse is every turn a circle, send two pulses to the speed line

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:Will the 75KW4 pole motor can be used to increase the speed of the inverter?: can! The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.

Q:Laptop computer about electricity no electricity, is the power adapter problem?: "The adapter light is bright" is just a matter of line between the AC power supply and the power adapter, and the power adapter to the computer that line may be bad or the computer interface is not good. Practice shows that the adapter's computer interface where the line is most likely broken
