ROTOR, ROTARY ELECTRIC MACHINE, AND METHOD OF MANUFACTURING THE ROTARY ELECTRIC MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18547890 titled 'ROTOR, ROTARY ELECTRIC MACHINE, AND METHOD OF MANUFACTURING THE ROTARY ELECTRIC MACHINE

Simplified Explanation

The rotor described in the patent application consists of a first resin portion, a first core, a magnet, and a second core. The first core has a division surface where it contacts an adjacent first core, while the second core does not contact an adjacent second core. Structures are arranged around the main shaft, with a second resin portion formed between the circumferential end faces of adjacent second cores and magnets.

• The rotor includes a first resin portion surrounding a main shaft.
• A magnet is attached to the radial outside of a first core, which is in turn surrounded by a second core.
• The first core has a division surface for contact with an adjacent first core, while the second core does not contact an adjacent second core.
• Structures are arranged around the main shaft, with a second resin portion formed between the circumferential end faces of adjacent second cores and magnets.

Problems Solved

This technology solves the problem of ensuring proper alignment and spacing between the components of a rotor, such as cores, magnets, and resin portions, to optimize performance and durability.

Benefits

The benefits of this technology include improved rotor stability, reduced friction between components, and enhanced overall efficiency of the rotating machinery in which it is utilized.

Potential Commercial Applications

The technology could be commercially applied in industries such as automotive, aerospace, renewable energy, and industrial manufacturing for the production of high-performance rotors for various applications.

Possible Prior Art

One possible prior art for this technology could be the design of rotors in electric motors and generators, where similar components are used but with different configurations and materials.

Original Abstract Submitted

A rotor includes a first resin portion formed the periphery of a main shaft; a first core disposed the outer circumferential portion of the first resin portion; a magnet attached to the radial outside of the first core; and a second core disposed the radially outside end face of the magnet, wherein a plurality of structures in each of which the magnet is sandwiched between the first and second cores are disposed circumferentially around the main shaft, and a second resin portion is formed between the circumferential end faces of adjacent second cores and between the circumferential end faces of adjacent magnets, wherein the first core has a division surface on which the circumferential end faces of itself and an adjacent first core are in surface contact with each other, and wherein the second core is not in contact with an adjacent second core.
