An ABB drive has helped vacuum cleaner manufacturer Dyson improve its dust extraction at its Wiltshire research and development centre, saving the company over £6,000 a year on energy costs.
The test facility puts new Dyson vacuum cleaner prototypes through their paces with a battery of tests that include their ability to remove dust from surfaces. The dust produced for these tests needs to eventually be extracted to maintain a safe and healthy atmosphere. It is extracted from several test points by a motor driven fan. Originally switched direct-on-line (DOL) via a star-delta arrangement, this motor drew a large starting current that was causing fuses to blow regularly.
