Abstract
A method for manufacturing a main rotor for a generator is provided. The method includes printing at least part of a rotor shaft by a three-dimensional printing process. The step of printing at least part of the rotor shaft includes printing a plurality of closed outlets and a plurality of open outlets. A rotor core is printed by the three-dimensional printing process. The step of printing the rotor core includes printing a plurality of liquid coolant conduits that extend through the rotor core and fluidly connecting the plurality of liquid coolant conduits to the plurality of closed openings.
Claims17
A main rotor for a generator system, the main rotor comprising:
- a rotor shaft comprising a plurality of open outlets printed on the outward-facing circumferential face of the rotor shaft;
- and
- a rotor core that extends about the rotor shaft, the rotor core comprising a first plurality of liquid coolant conduits printed within the rotor core and connected to a closed area of the rotor shaft;
- wherein the closed area of the rotor shaft comprises a first, second, third, and fourth plurality of closed outlets that are axially spaced from each other and the plurality of open outlets;
- wherein the rotor core includes a second plurality of liquid coolant conduits fluidly connected to the third plurality of closed outlets, and a third plurality of liquid coolant conduits fluidly connected to the fourth plurality of closed outlets;
- wherein the rotor core includes a plurality of axially extending liquid conduits that span between the second plurality of liquid coolant conduits and the third plurality of liquid coolant conduits;
- and
- wherein the plurality of axially extending liquid conduits are disposed in a radially-spaced configuration.
A generator system comprising:
- a main stator;
- and
- a main rotor located within a cavity of the main stator, the main rotor comprising:
- a rotor shaft comprising a plurality of open outlets printed on the outward-facing circumferential face of the rotor shaft;
- and
- a rotor core that extends about the rotor shaft, the rotor core comprising a first plurality of liquid coolant conduits printed within the rotor core and connected to a closed area of the rotor shaft;
- wherein the closed area of the rotor shaft comprises a first, second, third, and fourth plurality of closed outlets that are axially spaced from each other and the plurality of open outlets;
- wherein the rotor core includes a second plurality of liquid coolant conduits fluidly connected to the third plurality of closed outlets, and a third plurality of liquid coolant conduits fluidly connected to the fourth plurality of closed outlets;
- wherein the rotor core includes a plurality of axially extending liquid conduits that span between the second plurality of liquid coolant conduits and the third plurality of liquid coolant conduits;
- and
- wherein the plurality of axially extending liquid conduits are disposed in a radially-spaced configuration.
