METHOD FOR MANUFACTURING ROTOR AND EXTRUSION JIG - A simplified explanation of the abstract

This abstract first appeared for US patent application 18438701 titled 'METHOD FOR MANUFACTURING ROTOR AND EXTRUSION JIG

The abstract describes a method for manufacturing a rotor by fixing magnets to a laminated iron core using resin materials and a cull plate.

• Magnets are fixed to a laminated iron core by filling resin materials through a cull plate into magnet accommodating holes.
• Resin materials are solidified to secure the magnets in place.
• Solidified materials remaining in the supply ports of the cull plate are removed using an extrusion jig.
• The extrusion jig has extrusion portions that protrude from the base and extrude the solidified materials.
• The extrusion jig includes a first extrusion portion and a second extrusion portion with different protrusion amounts.

Potential Applications: - Manufacturing of rotors for various electrical machines. - Industrial applications requiring precise magnet placement.

Problems Solved: - Ensures secure fixation of magnets to the iron core. - Facilitates efficient manufacturing processes.

Benefits: - Improved rotor durability and performance. - Cost-effective production of rotors.

Commercial Applications: - Electric motor manufacturing industry. - Renewable energy sector for wind turbines.

Questions about the technology: 1. How does the use of resin materials improve the manufacturing process? 2. What are the advantages of using a cull plate and extrusion jig in this method?

Original Abstract Submitted

A method for manufacturing a rotor includes fixing magnets to a laminated iron core by respectively filling resin materials through a cull plate into magnet accommodating holes that accommodate the magnets and solidifying the resin materials. The cull plate has supply ports from which the resin materials are supplied. The method further includes removing, from the cull plate, solidified materials of the resin materials respectively remaining in the supply ports of the cull plate by extruding the solidified materials with the extrusion jig. The extrusion jig includes a base having an opposing surface that opposes one end surface of the cull plate in a thickness direction, and extrusion portions that protrude from the opposing surface and extrude the solidified materials. The extrusion portions include a first extrusion portion and a second extrusion portion that has a smaller protrusion amount from the opposing surface than the first extrusion portion.
