Embodiment Construction

[0020] now turn to attached image figure 1 , a foldable slot liner and interface insulator combination 10, hereinafter referred to as slot liner 10, is shown in perspective view.

[0021] Slot liner 10 is a generally U-shaped member defined by short side walls 12 , bottom wall 14 and long foldable side walls 16 .

[0022] A fold line 18 exists between the short side wall 12 and the bottom wall 14 . Similarly, a fold line 20 exists between the bottom wall 14 and the long side walls 16 . These two fold lines 18 and 20 give the slot liner 10 a generally U-shape.

[0023] The foldable long side wall 16 includes three fold lines 22 , 24 and 26 which define four long side wall sections 28 , 30 , 32 and 34 . As understood through this disclosure, portion 28 insulates a portion of the first coil from the slot walls, portions 30 and 32 define an interface insulator, and portion 34 insulates a portion of the second coil from the slot walls.

[0024] as from figure 1 It is clear tha...

Abstract

Electrically insulating material so foldable as to form a slot liner and an interphase insulator combination so configured as to be inserted in the slots of the stator or the rotor of an electric machine to prevent coils from being in contact with the slot walls and to prevent separate coils inserted in the same slot to be in direct contact with one another is described herein.

Description

technical field [0001] The present invention generally relates to electric machines. More specifically, the present invention relates to a slot liner and interface insulator combination configured so as to be inserted in a rotor and / or stator slot of an electrical machine. Background technique [0002] The stator and rotor of an electric machine are usually made of stacked laminations provided with coil receiving slots, defined by protruding teeth therebetween. These slots need to be electrically insulated from the coils that will be inserted there. Insulating paper materials have been developed for this purpose. [0003] Traditionally, rolls of this insulating paper are cut and folded to form individual slot liners, which are manually or automatically inserted into the slots. These pads are generally U-shaped with arms sized to extend outside the slot, thus helping to guide the coils there while preventing contact between the coils and the stacked laminations. Once the ...
