摘要： Generator field endwinding blocking is described. The endwinding blocking has a spacer block for radial placement between rotor endwindings. The spacer block has a spacer body with a radially inboard end, a radially outboard end, a slot extending from the outboard end towards the inboard end, and at least one transverse hole formed on an outer surface of the spacer body, extending in a perpendicular direction towards the slot. A cap covers at least a portion of the outboard end. The cap has a radially inward portion received in the slot with at least one hole aligned with the at least one traverse hole, and at least one end extending beyond a periphery of the outboard end towards an adjacent endwinding. A fastener placed in the holes of the spacer block and the radially inward portion of the cap, secures the cap with the spacer block.

摘要： A rotor assembly includes a rotor core having winding slots, and one or more coils, which have slot-inserted segments included in the winding slots, and first and second end-turn segments external to the winding slots and located around opposite axial ends of the rotor core, respectively. The rotor assembly further includes a first containment band located around at least a portion of the first end-turn segments and configured to prevent the first end-turn segments from moving away from the rotor core radially, a second containment band located around at least a portion of the second end-turn segments and configured to prevent the second end-turn segments from moving away from the rotor core radially, and one or more sticks mounted in one or more of the winding slots, respectively. The first and second containment bands are retained via the sticks against moving away axially.
