The facility puts vacuum cleaner prototypes through their paces with tests that include their ability to remove dust from surfaces.
Dust produced is subsequently extracted from several test points by a motor driven fan. Originally switched direct-on-line via a stardelta arrangement, the motor drew a large starting current that was causing fuses to blow.
ABB Drive Alliance member APDS monitored power use over a week.
Results showed the 55kW dust extraction motor cost £284/week to run at 12p/kWh.
APDS fitted a 55kW ABB standard drive.
Monitoring showed electricity costs per week could be reduced to £163 by running the motor at 40Hz rather than 50Hz, giving a total annual saving of £6292.
