Rotor of a variable-reluctance synchronous motor

A rotor of a variable-reluctance synchronous motor comprising a plurality of identically shaped discs arranged adjacent to one another in sequence along an axis of rotation and along a total depth of the rotor that extends axially from one end of the rotor to the other, the identically shaped discs being identical in shape and orientation to one another so that all features extending axially through discs that make up the total depth of the rotor align exactly with one another,

• wherein each of said discs is a lamination and includes a plurality of apertures extending axially therethrough, wherein the shape and arrangement of the plurality of apertures in each disc is identical for adjacently oriented discs,
• wherein the identically shaped discs are arranged in a plurality of equally sized sub-groups of said discs arranged in sequence along said axis of rotation such that each sub-group includes an equal number of laminations and each sub-group thereby extends an equal sub-group axial depth along the total depth of the rotor,
• wherein each of the plurality of apertures in adjacently oriented discs are aligned with one another so that each of the plurality of apertures extends axially through the adjacently oriented discs,
• wherein each of said discs is angularly sub-divided into a plurality of polar sectors, each of said polar sectors having exactly two identically dimensioned through-cavities radially aligned with one another, each through-cavity of the two radially aligned through cavities for housing at least a magnet,
• wherein each magnet has a parallelepiped shape having predefined dimensions, and all the magnets are identical in shape and size with one another,
• wherein each magnet has a predefined depth that is equal to one another, said depth being smaller than the total depth of the rotor, and each magnet having a section area perpendicular to the axis of rotation that is equal to or smaller than an access area to said through-cavity, and
• wherein the access area of each axially aligned through-cavity is the same between adjacent discs and extends between the plurality of discs forming a cavity therethrough, the cavity extending parallel to the axis of rotation along the depth of the rotor.
