Q:Laptop power adapter is broken, which brand is better domestic
This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
I have encountered the same problem, plug in the adapter, or use the battery power, the battery alarm, not the battery charge, the power adapter can not be used. But the power can charge the battery. If the power adapter alone, one will automatically shut down. Measure the adapter voltage normally. And then to get the computer city maintenance department, gymnastics, it is a simple question, the original power line in the circuit board on the solder joints are loose, that is, Weld, resulting in insufficient current, no wonder, off the machine can charge, boot can not charge, It shuts down. Spent 100 yuan. Business really black. I saw the repair. On the welding a few times OK. No wonder, once I suddenly shot about, the adapter can be used. Later, how to shoot not work. However, although spent 100, but my computer's heat silicone grease for the whole, the computer CPU temperature is not so high before. The beginning of the maintenance staff said that the power management chip may be broken, if the bad to more than 100, then, no bad, just contact the problem, welding also received me 100, really depressed. In fact, you can say good, if the contact problem, certainly below 100.
Q:Why the number of motor poles increased, the inverter capacity will increase
The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor. The frequency converter should match the rated current of the motor, not the power of the motor.
Q:Is the laptop power adapter long-haul?
This is not good, If you need to shut down, then it is recommended that the power adapter plug from the board to pull down. Because if only pull the adapter and the computer plug so that the adapter will still have the internal current through, hear the small sound is actually the sound of the current. So it is recommended that the power adapter from the outlet on the unplugged, and the computer connected to the one do not have to pull, so that will not cause the power adapter power and convenient computer to open.
Q:How is the notebook with a power adapter?
Clear use: Home use and office with the laptop power adapter to buy a home (AC), the car with the laptop power adapter, to buy a car, you want to use the aircraft on the basis of the car with a The aircraft head on it. Home, car, plane, want to take into account, to buy a two-in-one, or three in one. But if you do not want a few bags of computer weight, you can put a home, put a car, the office put a, so you can not bring to bring, plug to plug, more convenient, you can also give people around
Q:Is the laptop power adapter AC and DC?
Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:Yaskawa inverter reported base blockade what is the reason?
For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
Q:How do I select a drive? Which brand is better
  8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside.     9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value.     10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.
Q:Variable frequency conversion frequency difference characteristics based on,
Whether it is variable speed control, or string resistance speed, are the cost of energy consumption.
