Abstract:
A device for tensioning a winding of a stator having a core, the winding including multiple winding bars which form, on at least one axial front side of the core of the stator, with ends of the multiple winding bars extending axially outward from the core, an expanding, funnel-shaped winding head, the device comprising:multiple winding supports distributed circumferentially relative to the winding head on the front side of the core; and pressure spring elements; a coupling member cut perpendicularly to an outer side of the winding head to form a U-profile that opens in the direction of the winding support, the coupling member having two U-legs, a U-base between the two U-legs, and being attached to the outer side of the winding head or to a side of the outer clamping plate facing the winding support; wherein the two U-legs of the coupling member extend in a surface line direction of the outer side of the winding head; wherein the U-base projects perpendicularly from the outer side of the winding head; wherein the winding support includes a recess formed complementary to the U-base in the region of the coupling member, the recess including a radial edge portion; wherein the radial edge portion of the recess projects into the U-profile perpendicularly to the outer side of the winding head and is attached in the circumferential direction by the U-legs; wherein two axial edge portions overlap the U-base perpendicularly to the outer side of the winding head and are attached in the surface line direction by the U-base; wherein the winding supports are axially supported by the front side of the core; wherein each winding support is supported by the funnel-shaped outer side of the winding head via at least one pressure spring element; and wherein winding supports are attached to the winding head in a circumferential direction and in a surface line direction of an outer side of the winding head and are arranged for adjustment or movement perpendicular to said outer side.
