Abstract

The electric machine includes a stator wound with HV cable and is provided with stator teeth (104) extending radially inwards from an outer yoke portion (123). At least one stator tooth in a tooth sector (18) is provided with at least one axially-running cooling duct (124) connected to a cooling circuit. The latter accommodates a coolant that is arranged to circulate and in that the axially-running cooling tube is connected at least at one end of the stator to a clamping device (126). That is for axial compression of the stator. all cooling tubes in the figure shown are also radially aligned. Each cooling tube (124) is electrically insulated and provided with an insulating layer, not shown, in order to avoid contact with the metal in the stator tooth (104) or in the outer yoke portion (123). A thermally conducting glue may alternatively be used for attachment.
