Abstract: A variable frequency generator (VFG) rotor can include a plurality of windings configured to form a plurality of magnetic poles, each winding comprising a first winding end and a second winding end, and a first winding support structure comprising a plurality of first winding support segments configured to retain a first portion of each winding, each winding support segment being configured to move radially relative to an axis of rotation of the rotor. The first winding end of each winding extends from each winding support segment. The rotor can include at least one flexible bus bar jumper connected to two first winding ends of adjacent windings and configured to flex with radial movement of the winding support segments of respective windings attached to the flexible bus bar jumper.

Abstract: A method of installing the terminal block assembly onto a generator includes the step of providing a terminal block with multiple terminal studs. Protrusions that are integral with the terminal block are aligned with corresponding bores in a generator housing. The terminal block is mounted on the generator housing with the protrusions received in the bores. A terminal lead assembly is inserted through the protrusion, and a terminal pad of the terminal lead assembly is arranged over the terminal stud. A terminal lug is fastened to the terminal stud. A terminal cover is secured to the terminal block over the terminal with a boss of the terminal block received in a corresponding recess of the terminal cover.
