ROTATING ELECTRIC MACHINE AND METHOD FOR MANUFACTURING ROTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18330456 titled 'ROTATING ELECTRIC MACHINE AND METHOD FOR MANUFACTURING ROTOR

Simplified Explanation

The abstract describes a rotor for a rotating electric machine that includes a rotating shaft and a permanent magnet. The rotor also includes a sleeve made of a carbon fiber reinforced polymer that covers the outer surface of the permanent magnet. A resin film is joined to the outer circumferential wall of the sleeve, and a plurality of ridges are formed on the resin film. A riblet, which is recessed relative to the ridges, is formed between the ridges.

  • The rotor includes a rotating shaft and a permanent magnet.
  • A sleeve made of carbon fiber reinforced polymer covers the outer surface of the permanent magnet.
  • A resin film is joined to the outer circumferential wall of the sleeve.
  • The resin film has a plurality of ridges formed on its outer circumferential wall.
  • A riblet, which is recessed relative to the ridges, is formed between the ridges.

Potential Applications:

  • Electric motors
  • Generators
  • Wind turbines
  • Electric vehicles

Problems Solved:

  • Provides a protective covering for the permanent magnet
  • Enhances the strength and durability of the rotor
  • Reduces friction and drag during rotation

Benefits:

  • Improved performance and efficiency of the rotating electric machine
  • Increased lifespan of the rotor
  • Reduced maintenance and replacement costs


Original Abstract Submitted

A rotor constituting a rotating electric machine includes a rotating shaft and a permanent magnet. A sleeve covering the outer surface of the permanent magnet is attached to the rotating shaft. The sleeve is made of a carbon fiber reinforced polymer. A resin film is joined to an outer circumferential wall of the sleeve via a joining material. A plurality of ridges are formed on the outer circumferential wall of the resin film. A riblet recessed relatively to the plurality of ridges is formed between the plurality of ridges.
