General  of MV VFD Inverter Frequency

MV VFD Inverter Frequency is 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.

 

Application Filed of MV VFD Inverter Frequency

MV VFD Inverter Frequency can usually be applied in these fields:

Power generation: induced draft fans, forced draft fans, condensate exhausting pump, boiler feed water pumps, primary fan, secondary fan, circulating pump, mill fan, slurry pump, mill .

Metals: dusting fans, slurry pump, feeding pump, furnace fans, compressor, mill

Cement:  fan, discharge fan, waste gas fan, dust collecting fan, dust removing fan, mill.

Oil & Gas: water injection pump, oil transfer pumps, air compressor.

Mining: Fans, media pump, circulating pump, gas pump, oil separating pump, compressor, lift, mill, conveyer, hoisting machine.

Water: water supply pump, circulating pump.

 

System Principle Of MV VFD Inverter Frequency

Inverter Frequency

Q:How to choose the right inverter?
2, constant torque load Constant torque load equipment requires low frequency inverter torque, dynamic response speed. Inverter 0HZ vector state, to 150% of the torque, to meet the needs of various conditions. For example: a dredger owner bucket inverter system, is a constant torque load, dual motor, and the load overload time is long, so the inverter configuration configuration to enlarge the two models of the G-type machine, while the power supply for the device Machine power supply, the inverter must be configured to input AC reactor.
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:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
You can only use constant torque type of inverter. Motor selection frequency conversion motor. Driving is no problem
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:Laptop power adapter in the ring is how is it?
Inductance and capacitive shock sound In fact, any inductance and capacitance work will be shocked, but some shocks are large, and some shocks are small, the frequency is not the same, and some sounds harsh, some not harsh, and some ears can not hear the range Inside. Of course, this noise also has a certain standard, in fact, listen carefully, a lot of more power consumption of electronic equipment (tens of watts or more) have a voice. So, as you said to hear the sound is very small, sharp degree is not the same. This do not control, as long as they can endure, the general sound is not great, rest assured that good use of the performance and stability of no effect.
Q:I power adapter output current 3.25A for a 4.5A, can you use it
Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook
Q:What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
Bipolar input is positive and negative. Bipolar input is generally used to directly through the external reference or potentiometer to achieve the motor forward and reverse switching, without having to switch all the way to switch the signal (switch).
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:Laptop power adapter output voltage is not the same as the current? What's the effect?
so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
Q:Inverter alarm a043, how is it
Check processing: Check if the cable is disconnected. Check the tachometer to shield the ground. The shield is not only on the motor side, but also on the inverter side The cable of the pulse encoder should not be disconnected. The pulse encoder cable can not be laid together with the power loop cable. Use only the recommended pulse encoder.
