ROTARY ELECTRIC MACHINE WITH AXIAL COOLING

摘要

A rotating electric machine, comprising a stator (1) wound with high-voltage cable and provided with stator teeth (4) extending radially inwards in a tooth sector (18) from an outer yoke portion (22), wherein at least one stator tooth (4) is provided with an axially-running cooling duct connected to a cooling circuit (29) in which coolant (31) is arranged to circulate, and a method of cooling a rotating electric machine provided with high-voltage stator windings, where the stator winding is cooled by a coolant (31) being caused to circulate in a cooling circuit (29) through cooling tubes (25) running axially through the stator (1).
