Abstract
A method of forming a retention structure including magnetic regions and non-magnetic regions includes positioning one or more magnetic materials over one or more magnets of a rotor assembly and positioning one or more non-magnetic materials over one or more spacers, the spacers being positioned between the one or more magnets. The method also includes forming a cylindrical retention structure sized to fit around the one or more magnetic materials and the one or more non-magnetic materials. Forming the cylindrical retention structure is implemented via a three-dimensional printing process.

A method of forming a retention structure including magnetic regions and non-magnetic regions, the method comprising:
- providing a rotor assembly including a shaft and a pole retention structure;
- mounting a plurality of magnets on the pole retention structure;
- positioning one or more magnetic materials over one or more magnets of a rotor assembly;
- positioning one or more non-magnetic materials over one or more spacers, the spacers being positioned between the one or more magnets;
- and
- forming, via a three-dimensional printing process, a cylindrical retention structure surrounding the plurality of magnets, wherein the cylindrical retention structure comprises:
- the magnetic regions comprising magnetic materials, wherein each of the magnetic regions is aligned with a corresponding magnet of the plurality of magnets;
- and
- the magnetic regions comprising non-magnetic materials, wherein each of the non-magnetic regions is aligned with a corresponding space between each of the plurality of magnets.
