【発明の名称】半径方向に冷却を行う回転電気機械
Document Type and Number:
Japanese Patent JP2000511394
Kind Code:
A
Abstract:
A rotating electric machine comprising a stator (1) wound with a high-voltage cable and provided with stator teeth (4) extending radially inwards from an outer yoke portion (5), wherein at least one stator tooth (4) is connected to at least one cooling tube (18) running radially in the stator tooth (4) and connected to a cooling circuit (34) in which coolant (36) is arranged to circulate and wherein the cooling is arranged to take place over at least most of the axial extension of the stator tooth (4), and also a method of cooling a rotating electric machine provided with high-voltage stator windings, wherein the stator is cooled by a coolant (36) being caused to circulate in a cooling circuit (34) through cooling ducts running radially through the stator teeth (4).
