ABSTRACT:
A centrifugal filter for a high speed electrical machine of the type having a fluid flow path through its rotor. The centrifugal filter includes an enlargement at the beginning of the flow path through the rotor and which extends radially outwardly of the axis of rotation. As a consequence, contaminants in an incoming fluid stream are subjected to centrifugal force during operation of the machine and moved thereby radially outwardly within the enlargement so as to be out of the fluid stream. Consequently, the fluid stream, after separation of the contaminants therefrom within the enlargement by centrifugal force, may be passed with safety through the rotor for cooling and/or lubricating purposes.
