  • Patent number: 6825585
    Abstract: An end plate (1, 11) for a stator (31) wound with a cable in a rotating electric machine, the plate (1, 11) being provided with axially running winding slots (2) corresponding to the stator (31) and axially running apertures (19, 21, 22, 26) for cooling tubes corresponding to the stator (31), and that the plate (1, 11) is provided with at least one bending member (20, 23, 27) pre-shaped in the plate (1, 11) for cooling tubes (33) insertable into the cooling-tube apertures (19, 21, 22, 26) and also a procedure for supporting and protecting a cooling tube in a first axially running aperture at its exit from a stator in a rotating electric machine, whereby an end plate provided with bending members is applied at the end of the stator, the cooling tube being bent around the bending member before continuing, either by being fitted in a second axially running aperture in the stator or for extension out of the stator.

  • Patent number: 6646363
    Abstract: The invention relates to a rotating electric machine comprising a stator (4) provided with windings drawn through slots in the stator, and a rotor (1) having a central axis (2) and poles (5, 6) in the form of pole pieces (8, 9) provided with windings and forming solenoids, pole gaps (13) being arranged between the poles. The machine also comprises coil supports (15, 16) in said pole gaps in order to support the solenoid windings (10, 11). It is characterized in that the coil supports (15, 16) are arranged in pairs and that each coil supports (15, 16) is shaped so that it supports only a part of the solenoid windings (10, 11) of the two adjacent poles (5, 6).

  • Publication number: 20020125788
    Abstract: A rotating electric machine, comprising a stator (1) wound with high voltage cable and provided with stator teeth (4) extending radially inwards from an outer yoke portion (23), wherein at least one stator tooth (4) in a tooth sector (18) is provided with at least one axially running cooling duct (24) connected to a cooling circuit (25) in which coolant is arranged to circulate and in that the axially running cooling tube (24) is connected at least at one end of the stator (1) to a clamping means (27, 28) for axial compression of the stator (1).
