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.
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:Three sets of batteries (540V) DC power supply U / f inverter.
It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
Q:Can the inverter be used to control the speed of the DC motor?
For the brush commutation DC motor, the speed of the output torque in a certain circumstances and the input voltage related. For this type of motor, use the inverter to control the output of the rectifier device that supplies power to the motor, which can control the speed.
For the brushless DC motor, the controller is in accordance with a certain law to change the form of stator winding power supply to produce a rotating magnetic field to drive the rotor rotation. That is, the DC motor controller outside the part of the AC motor and the structure and the principle has not much difference (see below. For such motors, with the inverter to replace the controller, and control the same as the AC motor Control the speed.
Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is asynchronous motor, then take the power, voltage matching ordinary inverter drive no problem, you only need to enter the appropriate parameters, such as current, power size and other parameters, and then off-line parameters from the adjustment (if the vector control run), you can run
Q:22kw.2 pole fan can use Fuji inverter?
according to the rated name of the fan brand and the inverter rated current control, select the current value match, or slightly larger The
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear.
5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place.
6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water.
7, single-phase motor: When the scene using single-phase motor, the inverter useless.
8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
If you worry about the small, with 18.5KW is far enough.
Q:Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
Whether the motor is abnormal roar, if any, you can adjust the inverter parameters in the motor carrier frequency
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
The inverter burns should be.
Your motor overload is relatively large,
