Abstract: An assembly for positioning a retaining ring includes a mandrel having an outer diameter smaller than an outer diameter of a rotor. The assembly also includes a seal assembly for sealing a circumferential retaining ring around the mandrel or the rotor, the seal assembly comprising a pair of seal plates situated around opposing ends of the retaining ring. Further, the assembly includes a hydraulic expansion device for providing a fluid pressure for hydraulically expanding the retaining ring until an inner diameter of the retaining ring is greater than the outer diameter of the rotor. Furthermore, the assembly includes a displacement device for providing axial movement of the seal assembly and the retaining ring.

Abstract: Embodiments of the invention relate generally to rotor installation systems and, more particularly, to permanent magnet rotor installation systems, including those having an in situ magnetizer or magnet insertion device. In one embodiment, the invention provides a rotor installation system comprising: at least one magnetizer for permanently magnetizing a ferromagnetic material; and an arbor for receiving a rotor having at least one portion including a ferromagnetic material, wherein the at least one magnetizer is positioned relative to the arbor to allow permanent magnetization of the ferromagnetic material.
