Cooling arrangement of an electrical machine
First Claim
1. A component of an electric machine, the component comprising:
- a core;
two or more teeth extending radially from the core;
at least one electromagnetic winding, each winding being arranged around at least one of the teeth;
whereinthe core has a cooling arrangement comprising at least one cooling insert being bonded to the core and located between adjacent windings, the at least one cooling insert defining a cooling fluid flow duct, the at least one cooling insert including only a single material with high thermal conductivity and low electrical conductivity; and
a cooling fluid is arranged to flow through the at least one cooling insert to facilitate heat transfer and dissipation from the electromagnetic windings.

Abstract
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.
