Using simple two-conductor cables, it could allow Ethernet to replace proprietary serial communications and support links from the shopfloor to the cloud. 34 Transportation Industrial automation and motion technologies are increasingly being applied in all forms of transportation, on roads, in the air and on the water. We report on some recent developments. 46 Food Production A novel robotic food-cutting machine is allowing a Somerset dessert manufacturer to slice cheesecakes and other products on-the-fly. The inline system will boost the producer’s throughput, as well as widening the range of products that it can cut. 48 Motors Although no specification has been agreed yet for what constitutes an IE5 efficiency motor, several motor manufacturers are already offering machines that, they say, comply with IE5 requirements. An expert explains what’s going on. 51 Drives In what is thought to be the first installation of its type, a chairlift in an Austrian ski resort is being driven directly by 90-pole synchronous servomotors, eliminating the need for a gearbox, and doubling the lift’s passenger-carrying capacity. 52 Machine Building When designing a system to test airbag diffusers, a German machine-builder opted for a flexible linear transport technology that gave it the flexibility that a conventional rotary indexing table could not deliver. The resulting machine is achieving average cycle times of less than two seconds. 18 3 63 52 ANNUAL BUYER’S GUIDE This issue contains the 2019/2020 edition of the industry “bible” for power transmission, automation and motion engineers, telling you who sells what and how to get in touch with them.
