Variable-speed drives enhance productivity as well as energy efficiency

Variable-speed drives are an excellent means of reducing the energy consumption of the motor-driven application they’re connected to. For example, power usage in pumps, fans and conveyors can be halved simply by reducing motor speed by 20 percent. Plus, the initial cost of a VSD can be recouped in energy savings within as little as six months.

Energy saving is a huge advantage to VSD users, and our clients have enjoyed significant reductions in their electricity bills since installing them. But what about the other major benefit – productivity?


By optimising the speed of a process, a drive enables the user to maximise valuable production time and get the most out of their equipment.


By accurately regulating speed in a motor-driven process, a consistent quality of end product can be achieved, meaning less wastage for the manufacturer and a satisfied customer base.

Reduced maintenance

VSDs allow an electric motor to be brought up to speed gradually, which eliminates the mechanical shock associated with instant start-up. Sudden shock quickens the rate of normal wear and tear, which could lead to equipment failure and unscheduled downtime with obvious effects on productivity.

While energy saving will always be an important issue in the manufacturing sector, productivity should never be neglected. As an ABB drives supplier for many years we know that productivity is among our clients’ top priorities and we’re always on hand to recommend the ideal drive to fully optimise their application.
