Q:How to choose the right inverter?
2, constant torque load Constant torque load equipment requires low frequency inverter torque, dynamic response speed. Inverter 0HZ vector state, to 150% of the torque, to meet the needs of various conditions. For example: a dredger owner bucket inverter system, is a constant torque load, dual motor, and the load overload time is long, so the inverter configuration configuration to enlarge the two models of the G-type machine, while the power supply for the device Machine power supply, the inverter must be configured to input AC reactor.
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:Laptop power adapter is broken, which brand is better domestic
What brand of your laptop brand? It is best to be original,
Q:What is the output voltage of the laptop power adapter?
Generally have 19V of the common friends, I was 19V
Q:How to learn the inverter debugging and design parameters
You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
Under normal circumstances, with 15KW inverter on it.
Q:Notebook plug in the power adapter lights, but can not open the machine
1. Remove the power adapter and battery, the host does not power the case, hold down the boot button does not move, keep the notebook 30 seconds to release the residual static electricity; 2. Connect the power adapter separately to try to power on; 3. Connect the battery separately to try to boot; 4. If conditions permit, you can plug the memory test.
Q:Laptop power adapter how to detect?
No voltage output when no load.
Q:Does the inverter set the number of poles to match the number of poles of the motor?
Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.
Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
