Q: Is the laptop power adapter high temperature normal? Is there anything else?: Summer heat is normal, as long as it is not the kind of hand touch on the bubble temperature, no problem

Q: Laptop power adapter current is not the same alternative?: so the output voltage, the same output polarity, the output current of the adapter can be used in smaller power notebook, and small power adapter can not be used to give Powerful notebooks,

Q: Laptop adapter heat: Many friends to buy a laptop or laptop power, you may encounter the power did not take long to heat on the hot, and even hot to dare not get the situation, in the end is the quality of power problems or how is it? With the ever-changing notebook frequency, notebook power adapter power is also sesame flowering high, even to 100W or so, almost a small desktop power! Touch the hand, timid may be scared, obediently, is simply a hot potato! What will not fire? This is a lot of people worry! Compaq, IBM, such a large company to recover several back to the power adapter, it is because of fear that there may be defects due to power supply design, and will cause a fire!

Q: 6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: To 400HZ, so high frequency you tried it? I only tried 80HZ, if you tried, please tell me some of the high frequency of the actual situation will produce some changes in the motor,

Q: Laptop power adapter problem: First, that is called the transformer, not called the charger, not with you bite the word, but you according to the charger to Taobao search, basically one hundred percent are not found.

Q: Can the inverter be used to control the speed of the DC motor?: The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.

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 meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?: Analog signal input: Reference setting Input voltage Positive terminal (0 --- 10V)

Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?: This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),

Q: Does the inverter set the number of poles to match the number of poles of the motor?: The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
