A stator assembly for an electrical machine comprises a stator, a plurality of inserts and a heat sink. The stator comprises an annular core extending around an axis (X) and a plurality of axially extending slots. A plurality of sets of electrical windings is arranged within the slots. The windings have axial end portions arranged at axial ends of the core. The inserts comprise ceramic plates which are arranged in respective slots in the gaps (G) between adjacent respective electrical windings in the slots. The inserts extend axially from the respective slots for engagement with the heat sink.

Electrical machines

A stator assembly for an electrical machine comprises an annular core extending around an axis (X) and comprising a plurality of axially extending slots. A plurality of electrical windings are arranged in the slots and have end portions arranged at the axial ends of the core. A cooling jacket at least partially extends around a radially outer surface of the core. At least one annular cooling plate is mounted to an axial end of the cooling jacket and arranged in thermal contact with the end portions of the electrical windings.
