- Q: 4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
- About 2,000 yuan, electromagnetic speed and vector inverter can bring feedback
- Q: Laptop power adapter is broken, which brand is better domestic
- What brand of your laptop brand? It is best to be original,
- Q: Can the laptop power adapter be generic?
- Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
- Q: Laptop power adapter in the ring is how is it?
- Is the voice of the transformer, do not have to buy, will be used on the line.
- Q: What is the single axis of the inverter and multi-axis applications
- Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor power supply frequency and amplitude of the way to control the AC motor power transmission components.
- Q: Can the notebook's power adapter be mixed?
- In general, the same brand of notebook power adapter, as long as the same wattage, the same interface, can be mixed with. But do not recommend different brands or different wattage power adapter mix. Because the output wattage is different, there may be damage to the notebook, such as voltage instability and so on.
- Q: Delta VFD-F frequency converter how to adjust the number of poles
- Go to the official website of some inside a detailed description
- Q: What is the characteristic of the variable pole speed 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: The process of the slip loss back to the grid or production machinery, the higher efficiency; device capacity and speed range is proportional to the investment province, for speed range in the rated speed of 70% -90% of the production machinery; Device failure can be switched 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. Fourth, winding motor rotor series resistance speed control method Winding asynchronous motor rotor series into the additional resistance, so that the motor slip increase, the motor running at a lower speed. The greater the resistance of the series, the lower the motor speed. This method is simple and easy to control, but the slip power is consumed in the form of heat. Is a level of speed, mechanical characteristics of soft.
- 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: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.
