ELECTRICAL MACHINE HAVING COOLING FEATURES

摘要

An electrical machine has passages in the rotor. The passages have an inlet port and an exit port disposed at different locations. The passages remove heat from the electrical machine during operation. Another embodiment is an electrical machine rotor. The rotor has passages that remove heat from an electrical machine during operation. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for electrical machines and the cooling of electrical machine rotors and/or stators.

主权项

1. An electrical machine rotor, comprising:
a rotor for electromagnetic cooperation with a stator of an electrical machine and structured to rotate about an axis of rotation, wherein the rotor extends along the axis of rotation and includes a first cooling passage extending therethrough and having a first cooling fluid inlet port disposed at a first axial location along the axis of rotation, the first cooling passage also having a first cooling fluid discharge port in fluid communication with the first cooling fluid inlet port and disposed radially outward of the first cooling fluid inlet port at a second axial location spaced apart from the first axial location in a first axial direction along the axis of rotation, wherein the first cooling passage removes heat from the rotor during rotation of the rotor.
