Generator assembly

摘要

An electric machine, such as a generator, providing for the generation of electricity and includes a rotor generating a magnetic field and a stator having stator windings. The interaction of the magnetic field with the stator windings generates current in the windings. The generator may provide the generated current to a power output of the generator, where it may be further transmitted to an electrical load to power the load.

1. A generator assembly comprising:
a stator having a core with multiple poles; stator windings wound about the poles to define winding end turns at an end of the poles; a heat transfer element having a body defining a face confronting the end turns and comprising an aluminum alloy including a predetermined amount of Silicon Carbide (SiC) providing the body with a first coefficient of thermal expansion; and a thermally conductive, dielectric coating deposited on at least a portion of the face of the heat transfer element and in physical contact with the stator windings, and having a second coefficient of thermal expansion; wherein the predetermined amount of SiC is selected such that the first and second coefficients of thermal expansion are related that the thermal expansion of the heat transfer element and the dielectric coating in response to exposure to heat from the end turns will not result in through-cracking of the dielectric coating during normal operation of the generator.
