Unified assembly for slot cell insulation

The present invention facilitates keeping the slot cells of a generator rotor from migrating during operation of the rotor. The present invention utilizes a slot cell catch that hold slot cells , both U-shaped and L-shaped, in position within a rotor body slot . The catch limits movement to a pre-determined amount, usually only a fraction of an inch. The catch can withstand the forces of rotor in operation, and the limitation in migration reduces the need for inspection on the slot cells as well as lowering the risk of grounds being created between the windings and the rotor body
