What Are AC Drives ?

AC drives are applied in the process and discrete manufacturing industries, commercial buildings, and municipal infrastructure.  They provide speed, motion, and torque control for equipment, such as fans, pumps, compressors, conveyors, kilns, centrifuges, mixers, hoists, cranes, extruders, printing machinery, and textile machines. 

The demand for decarbonization and achieving the net zero emission targets propels the adoption of AC drives. Deployment of AC drive technology helps to reduce energy consumption and carbon emissions. Indus-trial operations continue to optimize performance, increase energy efficiency, and minimize waste to balance rising energy demand and support global warming initiatives.

ARC research on the AC Drives market reveals that digitalization enables ease of maintenance, productivity, and efficiency, that is necessary for sustainable plant operations. Digitalization in the drive technology allows transparency and easy access to relevant data of motors and converters, data analysis, monitoring the status and performance of the drive system, and to predict equipment failures beforehand, minimizing unnecessary shutdowns that can cost millions of dollars.

Low power AC drives comprise the micro (<5 kW), low-end (5-40 kW), and midrange (>40-200 kW) drives. 

High power AC drives comprise the midrange (41 kW to 200 kW), high-end (201 kW to 600 kW), and mega (>600 kW) AC drives.

Medium voltage AC drives are predominantly higher power drives that are greater than 0.2 MW.  The heavy industries, such as mining, metals, electric power generation, cement & glass, water & wastewater, marine, and oil & gas widely use medium voltage AC drives.  The medium volt-age AC drives market includes the following power ranges: >0.2-0.6 MW; >0.6-3 MW; >3-7.5 MW; >7.5-10 MW; >10 MW-20 MW; and >20 MW.
