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 20240235293 titled 'ROTOR, ROTARY ELECTRIC MACHINE, AND METHOD OF MANUFACTURING THE ROTARY ELECTRIC MACHINE

The abstract of the patent application describes a rotor design that includes a first resin portion, a first core, a magnet, and a second core, all arranged around a main shaft.

• The first resin portion is located at the periphery of the main shaft.
• The first core is positioned on the outer circumferential portion of the first resin portion.
• A magnet is attached to the radial outside of the first core.
• The second core is placed on the radially outside end face of the magnet.
• Multiple 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 circumferential end faces of adjacent second cores and between the circumferential end faces of adjacent magnets.
• The first core has a division surface where its circumferential end faces and those of an adjacent first core are in surface contact.
• The second core does not make contact with an adjacent second core.
