Q:Acer laptop power adapter
the price is not very clear. You can go online to see the price such as Taobao
Q:Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
It is wrong; the higher the speed is not equal to the greater the power;
Q:How to choose the right inverter?
, fan, pump load This is the most suitable for use in frequency conversion speed of the scene environment, the inverter function technology is not too high requirements, the use of inverter energy saving effect is remarkable. For example: a large-scale heating equipment in a large-scale heating system, including blower, induced draft fan (centrifugal fan) inverter configuration configuration with the power of the P-type machine; water pump (centrifugal pump) inverter configuration configuration with the power of the P-type machine ; Conveyor pump frequency converter selection configuration with the power of G-type machine; belt machine (coal feeder) inverter configuration configuration to enlarge a file of the G-type machine; slag converter inverter configuration configuration to enlarge a file of the G-type machine; Crusher (coal crusher) inverter configuration configuration to enlarge a file or two stalls of the G-type machine.
Q:Can the notebook's power adapter be mixed?
At present, the market sales of notebook power is generally 90 watts and 65 watts two, using integrated graphics, or configure the low-end notebook, usually 65 watts. Using the independence was, the configuration of high-end, or the game audio and video of this, are generally 90 watts. If the laptop's power adapter is damaged can not be used, it is best to repair the department as soon as possible to repair. If it is for emergency, before using the two adapters to check the output power and current and voltage are conceded, as the adapter input current and voltage is not the same, should be the general household voltage is 220V, so almost all of the notebook power The adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and wattage equal, and then one is the same interface, you can mix. In general, the voltage is stable, the output wattage is the same, the notebook is basically no harm.
Q:Speed of 3000 r / min three-phase motor how to change its speed
The key lies in two points: 1, you ask the variable range is how much? 2, your motor had a few qualifying? If your motor is 6 outlet, and you only need to speed, plus your motor is also an asynchronous motor, and you do not have the requirements of the load; then congratulations, you can achieve "speed" You just put the motor wiring way to do a △ - Y or Y - △ conversion can be achieved. If the above conditions you have one or two can not meet, then your best way is to buy a drive to achieve the variable speed. Of course, you can also make some changes to the winding to achieve the so-called single-winding multi-speed operation (this change, but the need for a certain technical content).
Q:What is the number of parameters of the motor frequency of the Siemens inverter?
Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
Q:How to choose the inverter
Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same It is important that the inverter life, stability, price comprehensive consideration Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on
Q:HP laptop power adapter how to open
Adapter is broken is difficult to repair, for a barThe common method is to insert the blade into the gap in the middle of the adapter and then pry open
Q:What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
That is to say that the potentiometer at both ends of the line between + 10v and -10v, tap can be given with a potentiometer to control the positive and negative!
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
