| 摘要 |
The invention relates to a component such as a rotor or stator (1) for an electrical machine. The component includes a plurality of axially adjacent stacks (4) of laminations. At least one pair of adjacent stacks are spaced apart in the axial direction by spacer means (6) such that a passageway or duct for cooling fluid, e.g. air, is formed therebetween. The spacer means (6) comprises a porous structural mat (8) of metal fibres (10). The cooling fluid may flow through the spaces or voids between the fibres (10). |
