Original Abstract Submitted
An electrical machine is provided. The electrical machine comprises a housing enclosing a rotor and a stator, wherein said stator comprises a stator core and end turns extending axially beyond the stator core. The electrical machine further comprises a first cooling system providing a flow of oil to the end turns of the stator, and a second cooling system having an axial end section overlapping the axial position of the end turns of the stator. The axial end section of the second cooling system is provided with one or more cooling fins.
