Abstract:
A high speed generator, comprising:a stator; and a rotor rotationally mounted within the stator, the rotor including: a shaft, at least a first and second pole, each pole extending radially outwardily from the shaft and spaced apart from one another to form an interpole region therebetween, and a coil support wedge positioned in the interpole region, the support wedge including: an integrally formed, longitudinally extending main body having at least a first end, a second end, and an outer surface, a first fluid passageway having an inlet port formed in the support wedge first end and an outlet port formed in the support wedge second end, a second fluid passageway having an inlet port formed in the support wedge second end and an outlet port formed in the support wedge first end, the second fluid passageway inlet port in fluid communication with the first fluid passageway outlet port, a third fluid passageway having an inlet port formed in the support wedge first end and extending at least partially into the support wedge to an end, a fourth fluid passageway having an outlet port formed in the support wedge first end and extending at least partially into the support wedge to an end, the end of the fourth fluid passageway in fluid communication with the end of the third fluid passageway; and a flow channel coupling the ends of the third and fourth fluid passageways in fluid communication with one another.
