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

The abstract of this patent application describes a rotor design that includes multiple components such as resin portions, cores, magnets, and structures arranged around a main shaft.

• The rotor features a first resin portion at the periphery of the main shaft, a first core surrounding the resin portion, a magnet attached to the first core, and a second core positioned at the outer end face of the magnet.
• Structures are arranged around the main shaft, with the magnet sandwiched between the first and second cores.
• A second resin portion is formed between the end faces of adjacent second cores and magnets.
• The first core has a division surface where its end face and an adjacent first core are in contact, while the second core does not contact adjacent second cores.

Potential Applications: - This rotor design could be used in various electric motor applications where efficient energy conversion is essential. - It may find applications in industries requiring precise rotational motion control, such as robotics or automotive systems.

Problems Solved: - The design addresses the need for a compact and efficient rotor structure for electric motors. - It ensures proper alignment and spacing of components for optimal performance.

Benefits: - Improved energy efficiency due to the optimized rotor design. - Enhanced durability and reliability of electric motor systems.

Commercial Applications: - This rotor design could be utilized in electric vehicles, industrial machinery, household appliances, and other devices requiring electric motors for operation.

Questions about the rotor design: 1. How does the division surface on the first core contribute to the overall performance of the rotor? 2. What are the potential cost implications of implementing this rotor design in mass-produced electric motors?

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.
