The Control Techniques Drives and Controls Handbook (2nd Edition)


File Size: 4.33 Mb

Description
With the rapid developments in the last 20 years in the area of industrial automation, it can be argued that the variable-speed drive has changed beyond all recognition. The functionality of a modern drive is now so diverse that its ability to rotate a motor is sometimes forgotten. Indeed, some customers buy drives not to control a motor but to utilise the powerfull auxiliary functionality that is built in. This is, however, unusual, and the drive remains a key component of the boom in all aspects of automation. Drives are also critical components in relation to energy saving. For over 30 years the case for energy saving through the use of variable-speed drives has been made by drive companies, and at last it seems that industry is moving quickly to adopting the technology. Consider the facts: 55–65 per cent of all electrical energy is used by electric motors. On average, fitting a variable-speed drive will save 30 per cent of the energy used by a fixed-speed motor, but today only 5 per cent of those motors are controlled by variable-speed drives. The opportunity is therefore enormous. Drives could save the world, or make a significant contribution to the cause. Before taking a brief look into the future it is helpful to look back at the relatively short history of drives and see how far and how quickly the technology has come.
