Cooling arrangement of an electrical machine

A component of an electric machine 46, the component comprising a core 10; two or more teeth 14 extending radially therefrom; at least one electromagnetic winding 12, each winding 12 around at least one of the teeth 14; wherein the core 10 having a cooling arrangement including at least one cooling insert 48 located between adjacent windings 12 and whereby in use a cooling fluid being arranged to flow through the at least one cooling insert 48 to facilitate heat transfer and dissipation from the electromagnetic windings 12. The cooling inserts providing improved cooling, structural support to the windings, and electrical insulation between the windings and the core.
