Abstract
A stator for a rotating electrical machine is disclosed, the stator comprising a stack of stator laminations () forming a stator core (). A lamination () comprises a plurality of cooling fins () arranged in at least one group of at least two fins. The cooling fins in a group are connected by a peripheral connecting member (). The laminations are arranged in packs of at least one lamination. A group of fins () in one pack of laminations lies circumferentially between two adjacent groups of fins in an adjacent pack of laminations. A cooling fin () in one pack of laminations is interposed between two cooling fins in a group of cooling fins in another non-adjacent pack of laminations. This can allow a good thermal performance to be achieved while at the same time providing good mechanical strength and being cost effective to manufacture.
