ABSTRACT:
A decanter centrifuge is provided with a dual motor drive for purposes of start-up and efficient operation. The two motors are coupled together during, at least, the start-up of the centrifuge rotation so as to provide the desired power requirements and to reduce the thermal load on the motors. After reaching operational speed, a first motor continues to drive the centrifuge at the desired operational speed and the second motor may be disengaged from operation. The dual motor drive may be varied by use of wye-start and delta-run phase connections for the motors. The operating conditions of the two motors can be varied to provide the necessary power while maximizing efficiency of the operation.
