Building a Sustainable Future with AC Drives

Overview

Energy savings is a crucial factor for sustainable industrial operations. AC drives offer tremendous potential for saving energy by controlling motors and adapting capacity to the exact power demand facilitating significant energy savings and smaller CO2 footprint. Adding an AC drive to a motor can save 25 percent energy or more. Improved speed control, process optimization, enhanced operating flexibility to suit the process needs, smooth torque over the entire speed range with reduced noise and vibration levels, minimal mechanical stress are some of the benefits provided by AC drives. Governments and public decision-makers are increasingly urging industries to adopt energy-efficient technologies such as AC drives to ensure a sustainable future going forward.

Electric motors are indispensable to the global economy and used widely in industries, running water treatment plants, refrigerating food, ventilating buildings, operating materials handling systems and so on. Motors account for more than half of the electricity consumption globally, so the impact of motors on the environment is enormous. The optimization of motor operation will result in considerable energy savings and help to make motors more environmentally friendly.

Energy Efficiency and Less Emissions

Increasing energy efficiency in all processes is crucial in preventing climate change. Industrial operations must continue to optimize performance, increase energy efficiency, and minimize waste to balance rising energy demand and support global-warming initiatives. Energy-efficient AC drives help to save a significant amount of energy by adapting capacity to the exact power demand rather than always running at full speed. This means less energy is wasted, especially since a small reduction in motor speed can result in energy savings and smaller CO2 footprint.

Motors are everywhere from pumps moving fluids to fans moving air to compressors, conveyors, and all type of machines that operate on rotational force. It requires advanced control to run optimally at all speeds. Low and medium voltage AC drives are designed for motors based on the requirements of the process rather than running them at full speed and reducing output using mechanical controls like throttles, dampers, or gears.

AC drives are deployed in numerous industries and application segments. These segments include building automation, cranes and hoists, marine and offshore, metals and minerals, chemical, automotive, semiconductor, oil & gas, infrastructure, food & beverage, pharmaceutical, machine, water & wastewater, elevators and escalators, pulp & paper, renewable solar and wind, etc.
