Abstract:
A reluctance rotor and method for manufacturing reluctance rotors having soft magnetic regions and regions with magnetic properties that are dissimilar to those of the soft magnetic region so as to create a flux barrier. The method generally entails producing a magnetic body having a central axis and an outer peripheral surface. The body is composed of concentric regions, at least one of which is a soft magnetic region while at least a second region of the concentric regions is formed of a material with dissimilar magnetic properties to the soft magnetic region. Once formed, the body is divided along radials thereof to form wedge-shaped members, with each wedge-shaped member having coaxial arcuate regions that are portions of the concentric regions of the body. As a result of the manner in which the body is divided, the wedge-shaped members have radial surfaces defined where the wedge-shaped members were divided from the body, and each wedge-shaped member also has a distal surface corresponding to the outer peripheral surface of the body. The wedge-shaped members are then arranged about an axis of symmetry corresponding to the axis of rotation of the rotor, with the distal surfaces of the wedge-shaped members disposed adjacent the axis of symmetry and facing each other, and with the radial surfaces of the wedge-shaped members facing away from the axis of symmetry.

US Classification:
310 44, 29598, 419 5, 31015656
Abstract:
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.

Abstract:
An electric machine for a vehicle comprising a shaft, a first one-way-clutch between the shaft and a driving member; and a second one-way-clutch between the shaft and a driven member is provided. The shaft is rotatably received within the electric machine. The first one-way-clutch transmits a first torque from the shaft to the driving member, but does not transmit a second torque from the driving member to the shaft. The second one-way-clutch transmits the second torque from the driven member to the shaft, but does not transmit the first torque from the shaft to the driven member.
