A spray disc is provided for a rotor assembly for an electric motor, comprising a spray disc body with an inner radius and an outer radius. The spray disc body comprises a first spray outlet and a second spray outlet, provided at or near the outer radius of the spray disc body and a spray disc conduit network, providing a fluid flow path between the inner radius of the spray disc body and the first and second spray outlets through the spray disc body, wherein the first spray outlet is axially offset from the second spray outlet. As such, a larger surface area of stator windings may be sprayed.
