- Q:Who knows how the inverter is calculated?
- There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.
- Q:Laptop power adapter in the ring is how is it?
- Notebook power adapter generally use the switch circuit, the output 12V DC power supply, as the notebook DC / DC converter circuit power supply; In the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire);
- Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
- The number of motor poles can be estimated by the parameters: 1000Hz corresponds to 60000rpm, According to "Speed in rpm = 60 * Frequency in Hz / (Number of Poles / 2)", Number of poles = 60 * Frequency indicated by Hz * 2 / Speed in rpm = 60 * 1000 * 2/60000 = 2 poles. The same is true with 333Hz and 20000rpm projections. The number of motor poles for the frequency converter should be entered with the number of poles of the motor that are directly connected to the frequency converter.
- Q:What is the laptop power adapter? Is it the battery?
- so that the book can be normal operation, or else you think the notebook is 220V Is the voltage at work?
- Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
- Q:Who knows how the frequency converter works
- Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.
- Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
- The motor speed is relative, the rated speed is the maximum speed
- Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- Then the motor nameplate on the standard 2P, it must be 2-pole motor, synchronous speed = 60 seconds x frequency (mainland 50Hz) / pole pairs, you can also look at the rated motor speed, about 2940 rev / 60s, so the inverter Set the number of motor poles, is set 2 pole, I hope you can be satisfied.
- Q:What is the single axis of the inverter and multi-axis applications
- Inverter is mainly used for AC motor (asynchronous motor or synchronous motor) speed adjustment, is recognized as the AC motor the best and most promising speed control program, in addition to excellent speed performance, the inverter is also significant Energy-saving effect, is the enterprise technological transformation and product upgrading of the ideal speed control device. Since the introduction of China since the 80s of last century, the frequency converter as energy-saving applications and speed of process control more and more important automation equipment, has been rapid development and wide application.
- Q:How to make the motor speed (control speed), can not use frequency
- In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
