ABB's variable speed drives control the speed of electric motors to match the task in hand, saving power and improving performance in industrial plants, shops, offices and homes, across the world.

ABB is the world’s leading supplier of AC and DC low-voltage drives and high-power, medium-voltage drives, with a product portfolio of drive systems that extends across a large power range, from 100 watts to 100 megawatts.

ABB drives are used to improve energy efficiency in most industries and applications, from single-phase residential and commercial buildings to huge all-electric drive systems that power entire natural gas liquefaction plants and gigantic gearless mill drives that grind ore and minerals into smaller pieces at mines and processing plants.

Here’s why you should invest in variable speed drives (VSDs) to improve the energy efficiency of your various applications, such as pump, fan, conveyor and compressor systems:

1. Improved operational efficiency.
   the need for manual labor is eliminated as the system controlled by drives can be automated, thus saving in man-hours and labor costs.
2. Savings on the electricity bill
   variable speed drives use only the needed amount of energy by running the motors at partial load, which can result in to 50% reduction in energy consumption of the drive system.
3. Savings in capital expenditure
   immediate reduction in electrical consumption ensures fast financial payback for the VSD investment, in pump and fan applications even within months of installation.
4. Savings in maintenance and spare part costs
   with drives, the stress on the mechanical equipment during startup and operation can be minimized ensuring a longer lifetime of the equipment.

This type of valuable gain can be achieved not only in large industrial operations but also in smaller installations as well.
