Patent ID: 6977459

Claim:
A locking strip system for anchoring a modular winding in an electrical machine wherein the winding has axially spaced winding supports and the machine includes a rotor having an axial slot, comprising: first and second elongated superposed locking strips each having a plurality of recesses spaced one from the other along a long edge thereof, said recesses being arranged in pairs thereof spaced one from the other along said long edge; a first recess of each pair thereof having a depth from said long edge greater than a depth from said long edge of a second recess of each pair thereof, each said first recess being spaced from one another along each said strip a distance corresponding to an axial spacing between axially adjacent winding supports and each said second recess being spaced from one another along each said strip a distance corresponding to the axial spacing between the axially adjacent winding supports; said pairs of recesses being arranged in repeating patterns along said long edge of each locking strip with the second recess of each pair thereof along said first locking strip lying adjacent one side of said first recess thereof and said second recess of each pair of recesses along said second locking strip lying adjacent an opposite side of said first recess of said second locking strip such that, with said locking strips superposed one over the other in an unlocked configuration, said first recesses of said first and second locking strips are aligned with one another to receive the winding supports and in a locking configuration with said strips displaced longitudinally relative to one another, said second recesses of said first and second locking strips are aligned with one another and portions of said strips engage the winding supports, precluding relative movement of the winding module and rotor in at least one direction.
