Abstract

In a method for mounting a prefabricated form-wound coil or tooth-wound coil on a layered laminated core to form a stator segment or stator, the form-wound coil or tooth-wound coil is insulated with insulation. Laminates are punched and stacked to form partial laminated cores and/or a laminated core, with the partial laminated cores being spaced apart from one another by spacers and forming substantially axially extending open slots of the laminated core. The form-wound coil or tooth-wound coil are radially inserted into the slots such as to embrace a tooth of the laminated core, and a removable auxiliary element is placed at an axial end face of the laminated core to protect the insulation of the form-wound coil or tooth-wound coil as the form-wound coil or tooth-wound coil is radially inserted into the slots. The auxiliary element is radially removed and repositioned on a further tooth of the laminated core.

First claim

What is claimed is:

1 - 6 . (canceled)

7 . A method for mounting a prefabricated form-wound coil or tooth-wound coil on a layered laminated core to form a stator segment or stator, said method comprising:
insulating the form-wound coil or tooth-wound coil with an insulation, punching and stacking laminates to form partial laminated cores and/or a laminated core, with the partial laminated cores being spaced apart from one another by spacers and forming substantially axially extending open slots of the laminated core; radially inserting the form-wound coil or tooth-wound coil into the slots such as to embrace a tooth of the laminated core; placing a removable auxiliary element at an axial end face of the laminated core to protect the insulation of the form-wound coil or tooth-wound coil as the form-wound coil or tooth-wound coil is radially inserted into the slots; and radially removing the auxiliary element and repositioning the auxiliary element on a further tooth of the laminated core.

8 . The method of claim 7 , wherein the auxiliary element is arranged on a first one or last one of the laminates of the laminated core.

9 . The method of claim 7 , wherein a partial laminated core of the partial laminated cores at the axial end face of the laminated core includes a pressure plate with pressure fingers, said auxiliary element being positioned on a respective one of the pressure fingers.

10 . The method of claim 9 , wherein the auxiliary element is additionally arranged on a respective one of the spacers between the partial laminated cores of the laminated core.

11 . An auxiliary element for aiding in mounting a form-wound or tooth-wound coil in slots of a laminated core, said auxiliary element comprising a basic structure arranged on an end face of the laminated core and configured in a form of a triangle with mutually facing curved legs.

12 . The auxiliary element of claim 11 , wherein the triangle is an isosceles triangle.

13 . The auxiliary element of claim 11 , wherein the basic structure has an upper part formed with an eye.

14 . The auxiliary element of claim 11 , wherein the legs have an extension formed with a releasable snap-fitting element for engagement in a recess of a tooth of the laminated core.
