摘要： A retention structure can be created using two or more different materials (e.g., one magnetic material, and one non-magnetic material) as a composite structure. The retention structure can include a cylindrical hoop comprising one or more one or magnetic regions tangentially alternating with one or more non-magnetic regions configured to surround and retain a plurality of magnets to a rotor, wherein the one or more magnetic regions are aligned with each one of the plurality of magnets and the one or more non-magnetic regions are aligned with one or more spaces between the plurality of magnets on the rotor. The magnetic material allows flux from the permanent magnets to flow through to the stators and the non-magnetic sections reduce leakage of magnetic flux to adjoining permanent magnets through use of non-magnetic materials. The retention structure can be fabricated using a hot isostatic press process.

摘要： A two-phase bipolar step motor comprises a rotor (41) having a plurality of pairs of rotor poles (43) of alternating (N and S) magnetic polarity, and a stator (45) having four primary energizable stator poles (46-49) with conductive windings (55-58) around those primary stator poles and four passive inter-poles (467, 478, 489, 496) located uniformly between every adjacent pair of primary stator poles, the passive inter-poles lacking any conductive windings. Both 18° steppers with five pairs of rotor poles (Figs. 4-9) and 30° steppers with three pairs of rotor poles (Figs. 10-15) are provided. Also provided are both PM hybrid mix steppers with 2D magnetic flux paths (Figs. 4-6, 10-12) and hybrid steppers with 3D magnetic flux paths having an axial component (Figs. 7-9, 13-15). In each case, the overall lengths of the flux paths are substantially reduced from conventional designs resulting in improved motor efficiency.
