Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
The inverter operates at constant speed below the base speed, and the output current of the inverter does not change as long as the load does not change.
Q:Laptop power adapter bad what is the phenomenon?
Either the power is bad or the machine on the power supply module is bad to repair service
Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
May be mechanical part of the card, try idling motor.
Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Is the inverter must be. Do not know you are also a generic vector. If it is common to directly on the instructions on the motor logarithmic change 6 pole, turn the number changed to 980 on the line. Vector, then change the number of 980 and then learn from the line on the line.
Q:The parameters of the inverter is 4, 6 motor can be used
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.
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
If you worry about the small, with 18.5KW is far enough.
Q:Laptop warranty period is not over, the power adapter is broken, repair money?
The general adapter is only one year warranty. And even some power warranty for three months.
Go to the official website of the notebook, see the specific information of the computer, which includes the computer parts of the specific warranty date and expiration date.
If the warranty period, as long as the purchase of the invoice, you can go to aftermarket replacement or maintenance.
Remember to bring an invoice, warranty card. It can not find the warranty card must find the invoice.
General power adapter is new.
Q:Laptop power adapter how to detect?
No voltage output when no load.
Q:The laptop power adapter is hot
Almost all of the notebook adapters have this problem, you do not have to worry about this. But do not know you can not tolerate what is the degree, if it is so hot that the adapter has a deformation, then it is recommended to immediately stop using, to the sale to the new
Q:What is the characteristic of the variable pole speed method?
Edit this paragraph speed method
First, variable pole alignment speed method
This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.
