Q: Three-phase asynchronous AC motor speed control method: Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.

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

Q: Lenovo laptop power adapter side of the feet which is positive: Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop.

Q: On the notebook power adapter output current and voltage issues: This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.

Q: What is the characteristic of the variable pole speed method?: Three-phase asynchronous motor speed formula: n = 60f / p (1-s) From the above equation can be seen, change the power supply frequency f, the motor pole p and slip rate s can achieve the purpose of changing the speed. From the nature of the speed point of view, different speed control mode is nothing more than to change the AC motor synchronous speed or do not change the synchronous turn two. In the production machinery is widely used does not change the synchronous speed of the speed control method There are winding motor rotor resistance, chopping speed, cascade speed and the application of electromagnetic slip clutch, hydraulic coupling, oil film clutch, etc. Speed ??control. Change the synchronous speed of the stator to change the number of pole pairs of multi-speed motor, change the stator voltage, the frequency of the frequency control can not change the motor speed and so on. From the energy point of view of the speed control point of view, there are two methods of efficient speed control and inefficient speed control: high speed control when the slip rate is constant, so no slip loss, such as multi-speed motor, frequency control As well as the speed loss can be recovered speed control methods (such as cascade speed, etc.). There are slip loss of the speed control method is a low efficiency, such as the rotor string resistance control method, the energy loss in the rotor circuit; electromagnetic clutch speed control method, the energy loss in the clutch coil; hydraulic coupling speed , Energy loss in the oil of the hydraulic coupling. In general, the slip loss increases with the speed range, if the speed range is not large, the energy loss is very small.

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: Do you want to pay attention to the number of poles of the motor when selecting the inverter?: Inverter selection is mainly to see the power, and then pay attention to voltage problems. Finally look at what your motor is carrying.

Q: With the inverter control fan 37Kw4 pole with what model inverter: Control the fan: select the fan pump with 37KW or 45KW inverter.

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: How to learn the inverter debugging and design parameters: Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
