A method of making composite electric machine rotor assembly of a desired magnetic pattern. Magnetic segments and non-magnetic segments are separately formed to green strength, and then arranged adjacent to each other in a desired magnetic pattern. A small amount of powder material is added in-between the segments, and the whole assembly is then sintered to form a sinterbonded composite component of high structural integrity.

Method of making a composite electric machine component of a desired magnetic pattern

An edge-connected non-thermal plasma reactor includes an element having an edge-connected frame comprising a pair of dielectric edge connectors secured at opposite ends to a pair of outer dielectric plates. The dielectric edge connectors have a backplane and a plurality of tines protruding along one major surface of the backplane. The tines are spaced apart from one another at regular intervals so as to form pockets between adjacent tines. Alternating polarity electrode plates comprising a dielectric barrier plate having an electrode and terminal connection lead disposed on the dielectric barrier are arranged within the edge-connected frame so as to define the presence of a dielectric barrier next to a plasma cell, with the pockets engaging opposite ends of the electrode plates. Double and single dielectric edge-connected reactor elements are provided.

Edge-connected non-thermal plasma exhaust after-treatment device

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.

Manufacturing method and composite powder metal rotor assembly for circumferential type interior permanent magnet machine

A method of making a composite powder metal disk for a rotor assembly in a synchronous reluctance machine. The method includes filling discrete regions of a disk-shaped die with ferromagnetic and non-ferromagnetic powder metals, compacting to powders, and sintering the compacted powders. By this method, a disk is formed that includes alternating regions of magnetically conducting powder metal and magnetically non-conducting powder metal compacted and sintered to a high density. The method may also include forming a rotor assembly by stacking a plurality of the composite powder metal disks axially along a shaft with their magnetic configurations aligned.

Method of making a powder metal rotor for a synchronous reluctance machine

A method of making a composite powder metal disk for a rotor assembly in a surface permanent magnet machine. The method includes filling inner and outer annular regions of a disk-shaped die with soft and hard ferromagnetic powder metals, compacting the powders, and sintering the compacted powders. By this method, a disk is formed that includes permanent magnets on the surface of an inner ring of magnetically conducting powder metal compacted and sintered to a high density. In one embodiment, non-ferromagnetic powder metal is filled into regions of the die such that the permanent magnets are separated by magnetically non-conducting powder metal compacted and sintered to a high density. The method may also include forming a rotor assembly by stacking a plurality of the composite powder metal disks axially along a shaft with their magnetic configurations aligned.
