ABSTRACT:
A centrifuge system and method according to which a conveyor is disposed in the bowl, and electrical motors are provided for rotating the bowl and the conveyor at different speeds. A DC bus is provided to store electrical energy which is supplied to the conveyor motor to rotate the conveyor if a brownout condition occurs. The bowl is braked in response to the brownout condition to generate electrical energy which is transferred to, and stored by, the DC bus for supplying to the conveyor motor.
