660v Medium Voltage Variable Frequency Drives

Product Description

660v 1100v 3300v 6600v Medium Voltage Inverter Vfd Vsd For Mining Industry



Medium Voltage Drive Description


Medium Voltage Vfd  are widely used in mining industry coal mining machine, continuous mining machine, shuttle car, conveyor, hoist, winch, emulsion pump, submersible pump, mine fan, water pump and other equipment. Furthermore, it has many functional features, such as excellent medium voltage drive performance, synchronized multi - function balance, low-frequency high-torque smooth start, improving self-learning and so on.


The advantage of Medium VFDs driving:

1) Simple structure and small size;

2) Compared with the two levels, the device can achieve 2 times the voltage output with the same voltage level;

3) Reduce the common mode voltage of the motor;

4) Reduce common mode interference to the power grid;

5) It is convenient to realize the two-way flow of energy and the four-quadrant operation of the motor;

6) The output du/dt is reduced by half compared to the two levels;

7) Compared with the two levels, the number of phase voltage output levels increases and the output harmonics decrease.

8)Significant energy savings

9)The constant current automatic control

10)Low torque pulse

11)Soft start


1). Substantial reduction of harmonic current on power source side

2). Total inverter effi ciency as high as approximate 97%

3). Source power factor as high as 95% or more

4). High-reliability

5). Vector control

6). Easy maintenance




Medium voltage drive suitable applications such as Centrifugal pumps, fans, and compressors, screw compressors, blowers, refiners, mixers, extruders, belt conveyors, mill pressers, kilns, mills, hot gas expanders, etc.
