Abstract
A stator for an electrical machine is described. The stator includes a plurality of axially adjacent generally annular laminations. An axially extending coolant passageway through which a coolant fluid flows in use, extends through the stator. A plurality of axially spaced sealing recesses are provided. Each sealing recess is located between a pair of laminations and is in open communication with the surface of the axially extending coolant passageway. Each sealing recess has an axial width greater than the gap between the facing planar surfaces of axially adjacent laminations and is at least partially filled with a cured resin material to define a plurality of axially spaced seals.
