Abstract

This invention relates to a rotary electrical machine, comprising: a laminated core having a plurality of laminations, the laminations defining a plurality of parallel circumferential channels in a surface of the laminated core for a flow of cooling fluid, wherein the plurality of circumferential channels each extend between an inlet and an outlet so as to provide a plurality of parallel circumferential flow flows of coolant when in use.
