Abstract

The paper describes a project to replace the drive of a pump in a waste water treatment facility. The existing drive has a peak output of 45 kW and is required to operate between 600 and 850 r/min which is obtained from a slip-ring wound-rotor induction motor using rotor resistive control. Of several possible electronically controlled drive configurations, the brushless doubly-fed machine has been selected for trial installation because of the advantages it appears to offer in this application.
