Delta Medium Voltage Drive
Delta MVD2000 Series
The MVD2000 is a medium voltage variable speed drive series for speed and torque control based on advanced
frequency-conversion multilevel inverter technologies and advanced vector control algorithms. The MVD2000 is a
modular and congurable cost-effective solution that provides efcient and reliable operation across many industrial
applications. Simple installation requirements, easy operation and maintenance make the MVD2000 the drive of choice
across industrial segments that require energy savings or speed control for constant torque loads over the operating
speed range.
MVD2000 delivers high performance control accuracy using vector control. The ability to independently control motor
ux and speed yields fast dynamic response to load uctuations and high torque at low speeds, including during motor
start-up.
Both encoder and sensor-less vector control approaches are available for selection. The speed sensors can be installed
depending on actual application conditions. For cases without the speed sensors, the system can still provide fast
dynamic responses and high output torque when the motor is running at low speed.
The MVD2000 series is applied for speed control of square torque loads such as fans, pumps, and
compressors, as well as for mills, crushers, and conveyor belts that require constant torque operation
over the entire speed range. Accurate speed and torque controls result in better energy saving, improved
process quality, and prolonged equipment lifetime. Various industry segments that require reliable and
stable operation can benet from MVD2000’s high performance:
• Power generation: coal mills, blower fans, and water pumps.
• Metallurgy: conveyor belts, positive displacement pumps, fans, and water pumps.
• Mining: crushers, conveyor belts, PD pumps, fans and water pumps.
• Oil & Gas: compressors, PD pumps, centrifugal pumps, fans and water pumps.
• Cement & Materials: crushers, mixers, extruders, rotary kilns, drying furnaces, fans and water pumps.
• Sugar & Ethanol: mills, pumps, and fans.
• Municipal works: water supply pumps, sewage pumps, heat network pumps.
