Q:What is the principle and implementation of the inverter?
How the inverter works: 1. DC can be converted into alternating current through the oscillation circuit 2. The resulting AC power is then boosted by the coil (in this case, the alternating current of the square wave) 3. Rectify the resulting alternating current to obtain a sine wave
Q:Three sets of batteries (540V) DC power supply U / f inverter.
This is the reason for the battery characteristics, your group of easy to burn the battery discharge characteristics of the curve should not be partial to engage, so easy to burn. Ultimately it is your group of battery quality is relatively poor!
Q:Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
The original you are the ordinary motor ah, this ordinary motor can not afford too high frequency. Often at high frequencies or low frequency work will burn the motor. The higher the speed, the current will increase, the lower the speed, the current will be reduced. Its power is not much change. You still with a special frequency control motor it. Frequency conversion motor is a special design, the use of frequency converter for the drive power, the motor and inverter electromechanical integrated frequency control system, so as to achieve low frequency constant torque operation and high frequency constant torque operation. This motor has good speed performance and significant energy saving effect
Q:The Schneider inverter reports the nlp command
Schneider inverter reported nlp ??? main circuit no electricity 1 re-power up 2 connected to the DC reactor terminals PO, PA / + between the short wiring, the main circuit can not be powered
Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor. 1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
With green wave Jie can experience to judge, there may be two possibilities: First, the inverter power selected small. Bipolar motor, not a four-pole motor, the inverter is designed according to the four-pole motor model, so in the inverter selection, can not only look at the power, but also the rated current of the motor;
Q:What is the difference between variable frequency motor and variable speed motor?
The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q:Do not the laptop directly connected to the power adapter?
2, due to the different configuration of the notebook, its power consumption also has a variety of specifications. Common for more than 60W, the configuration of some of the 90W, and the game adapter power in more than 120W, such as dual GTX1080 card crossfire Blue Star prototype, power consumption in more than 400W, the use of two 320W power adapter for its power supply;
Q:Can the four motors be tuned to 2900 rpm?
Can be used, there are problems you can consult Zhoukou City bearing mechanical and electrical companies, contact the online search Zhoukou City bearing mechanical and electrical companies can search to!
