Abstract
The present invention facilitates keeping the slot cellsof a generator rotor from migrating during operation of the rotor. The present invention utilizes a slot cell catchthat hold slot cells, both U-shaped and L-shaped, in position within a rotor body slot. The catchlimits 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 cellsas well as lowering the risk of grounds being created between the windings and the rotor body
