摘要： A rotor of an electric machine includes a rotor core having a plurality of longitudinally extending magnet channels each containing a permanent magnet, and a plurality of moldable containers each containing a heat transfer material and each being contiguous with portions of the respective permanent magnet and its magnet channel. A method of thermal management of an internal permanent magnet (IPM) rotor includes installing, into at least one longitudinally extending magnet channel of a rotor core, a permanent magnet having opposite lateral ends. The method also includes installing a moldable container, enclosing a heat transfer material, into the magnet channel adjacent one of the lateral ends of the permanent magnet. The method further includes transferring heat from the magnet through the container into the rotor core.

摘要： Methods, systems, and articles of manufacture for fastening internal cooling fans to claw-pole segments are provided. A claw-pole segment suitable for use in a rotor of an electro-mechanical machine is formed. The claw-pole segment may include a base portion, at least one claw pole projecting axially from the base in a first direction, and at least one protrusion projecting axially from the base in a second direction opposite the first direction. A fan assembly that attaches to the claw-pole segment is also formed. The fan assembly may include at least one opening for receiving the at least one protrusion, and may be formed with varying configurations to affect the frequency response of the fan. The portion of the at least one protrusion extends through and beyond the opening of the fan assembly when the fan assembly is mounted on the claw-pole segment and expands in response to an application of an axial load, to secure the fan assembly to the claw-pole segment.
