发明名称 Support members inside stator slots of a rotating electric machine and method of mounting these support members
摘要 A rotating electric machine ( 1 ) has a rotor, a stator ( 2 ), and stator windings ( 3, 4 ). The windings ( 3, 4 ) include high voltage cable drawn through slots ( 5, 6 ) in the stator ( 2 ). Support members ( 8 ) are arranged inside the slots ( 5, 6 ) along and in contact with the windings ( 3, 4 ), said support members ( 8 ) comprising a hose ( 8 ') with a substantially triangular cross-section. A wire ( 9 ) is extending through and being attached to each support member ( 8 ). When mounting the support members ( 8 ) air inside a support member ( 8 ) is evacuated in order to shrink the support member ( 8 ). Then the wire ( 9 ) extending through the support member ( 8 ) is used to pull the evacuated support member ( 8 ) into a slot ( 5, 6 ), whereupon the evacuated support member ( 8 ) is expanded by releasing the vacuum inside in order to make it clamp a cable inside a slot ( 5, 6 ) of the stator ( 2 ).
