Abstract: A 3D printed metal coil for an electrical machine. The 3D printed coil has a plurality of turns and is configured to fit within a slot in an electrical machine. A cross-sectional shape of successive turns of the plurality of turns varies such that a portion of each turn forms a part of an external surface of the metal coil, the external surface forming an interface with a side of the slot.

Abstract: An electrical machine is disclosed comprising a stator cavity. The stator cavity is axially divided by a distribution plate into a winding chamber containing stator windings of the electrical machine and a handling chamber. The handling chamber has one of a fluid inlet and a fluid outlet and the winding chamber has the other of the fluid inlet and fluid outlet. In use fluid is passed from the fluid inlet to the fluid outlet via the handling chamber, the winding chamber and an array of fluid passages in the distribution plate providing fluid communication between the handling chamber and winding chamber. The array of fluid passages comprises passages of at least two different cross-sectional areas.

Abstract: A method is provided for fabricating an insulated metal coil for an electrical machine. The method includes 3D printing a metal coil having a plurality of turns. The method further includes subsequently infiltrating insulating material between the turns of the metal coil to electrically insulate the turns from each other.
