METHODS FOR MAKING A LOW INERTIA LAMINATED ROTOR

摘要

A rotor assembly having a plurality of rotor plates mounted to a shaft, and methods of construction for a rotor assembly are disclosed. Each rotor plate in the assembly may be provided with a central opening extending between the first and second sides through which the shaft extends. In one aspect, the rotor plates are provided with a plurality of lobes extending away from the central opening, wherein each of the lobes has a lobe opening extending through the thickness of the plates. In one embodiment, the rotor plates are rotationally stacked to form a helical rotor.

1. A method of making a laminated rotor, the method comprising the steps of:
a. providing a plurality of rotor plates, each of the plates having a plurality of lobes extending radially away from a central opening and a first indexing feature; b. providing a mandrel having a second indexing feature; c. stacking each of the rotor plates onto the mandrel such that the mandrel extends through the central opening of each plate and such that the rotor plate first indexing feature is aligned with the mandrel second indexing feature; d. securing the rotor plates together; e. removing the mandrel from the rotor plates; and f. inserting a shaft into the central openings of the rotor plates.
