ELECTRICAL MACHINE COMPRISING A STATOR WITH WINDINGS

摘要

The invention relates to an electrical machine, for example a motor or a generator, comprising a housing (3) and therein a stator (2) comprising a tubular core (8) and windings (9) surrounding the core wall, said stator windings (9) extending axially and radially with respect to the axis of the core (8), the machine comprising means for cooling the windings (9). As well on the inside as on the outside of the core (8) the windings (9) are for at least 95 % spaced apart, forming gaps (11) between them, the cooling means comprising a cooling medium in these gaps (11).
