                                    High Voltage 3KV ~11KV AC Driver Inverter  

 

General


CNBM high Voltage Variable Frequency Drives are designed to be highly reliable with high-performance, yet easy to use.It can satisfy users' need for changing the speed of fans or pumps,as well as improve the productivity.

The series are compatible with all types of three-phase medium voltage asynchronous motors.

 

Advantages :


1. Voltage resource VFD, direct input of 3,3.3,4.16,6,606 and 10 kV,direct output of3,4.16, 6,6.6 and10 kV,no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required.
2. Sinusoidal multi-level PWM output waveform, no output filter required, can be directly connected to standard induction motor,no harm to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes,with the maximal length of the output cable of 1000m.

3. Friendly human-machine interface.
4. Modular design of the power circuits simplifies maintenance routine.

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:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In short, then connected to the bk-dk electrical appliances, is a resistor for the discharge effect
Q:Does the inverter set the number of poles to match the number of poles of the motor?
The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is synchronous motor, it depends on whether you choose the inverter is compatible with the synchronization machine, most of the incompatible. As you said the situation, the motor 8 pole, may be synchronous motor. Specifically, you can compare the rated speed and rated frequency to see if there is a slip rate to determine whether it is synchronous or asynchronous motor.
Q:ASUS notebook power adapter can be universal? is it?
ASUS notebook power adapter is not universal, depending on the model, the output voltage and current requirements are different, select the battery and consistent adapter. Note: different brands of laptop batteries may be different, so do not use, through the laptop battery voltage and current comparison power adapter voltage and current to judge. If the voltage and current are roughly the same can be used.
Q:On the notebook power adapter output current and voltage issues
This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
Q:Yaskawa inverter reported base blockade what is the reason?
This is the base block command, when the external input block command signal, the inverter will appear this code, the code appears, the motor will be free to rotate, does not affect the use.
Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?
11KW 4-pole motor and 2-pole motor is the difference between the motor coil winding is not the same, the appearance of the 2-pole motor to be slightly larger, the speed of 4 pole speed is 1450 r / min, 2 pole is 970 r / min
Q:380V motor addition to the inverter, but also how to change its speed?
Use the star connection to reduce the speed by changing the torque
Q:Why G120 inverter to be equipped with 4-pole motor?
I add point with the premise of the inverter is to understand the mechanical load characteristics (or process, etc.), can the parameters set.
