Summary:An electric machine comprises a core ( 10 ) of magnetic material and a first insulating layer ( 14 ) of a solid electrically insulating material surrounding the core. A high-voltage winding ( 17 ) in the form of an electric conductor is wound around a first part ( 16 ) of the first insulating layer and a field-equalizing member ( 19 ) is arranged around a second part ( 18 ) of the first insulation layer. Further, a second insulating layer ( 20 ) of a solid electrically insulating material surrounds the high-voltage winding and the field-equalizing member. The field-equalizing member comprises at least one first sub-member in the form of a winding ( 27, 28, 37, 38 ), and an electric cable conductor ( 31 ) is intended to be connected to the high-voltage winding at the field-equalizing member.
