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.
