摘要： A composite powder metal disk for a rotor assembly in a circumferential type interior permanent magnet machine. The disk includes an inner ring of magnetically conducting powder metal compacted and sintered to a high density. The disk further includes an outer ring of permanent magnets separated by magnetically non-conducting powder metal compacted and sintered to a high density. The permanent magnets additionally are radially embedded by magnetically conducting powder metal compacted and sintered to a high density with optional intermediate non-conducting powder metal bridges extending radially from the permanent magnets to the outer surface of the disk. A rotor assembly is also provided having a plurality of the composite powder metal disks mounted axially along a shaft with their magnetic configurations aligned. A method for making the composite powder metal disks is further provided including filling a die with the powder metals, compacting the powders, and sintering the compacted powders.

摘要： 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.

摘要： According to the invention, a rotor is provided having a cylindrical core and a protective can closely fit and secured with the core. The core is provided with two axially spaced, annular reliefs spaced inwardly from points of welding which secure the can and core and connected by at least two circumferentially spaced, axial reliefs. To effect removal of the can, a cutting tool is extended through the can along the extent of the reliefs. With the cuts completed, access sections are defined and are separable from the core. The remainder of the can, including the weld material, can be machined off using conventional techniques.
