ROTOR ELECTRICAL GROUNDING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17819701 titled 'ROTOR ELECTRICAL GROUNDING SYSTEM

Simplified Explanation

The abstract describes an electric machine grounding system with low impedance, which includes a rotor with a shaft assembly that rotates about an axis. The shaft assembly has a surface, and a housing supports the rotor for rotation. A holder extends from the housing, and a ground assembly is held between the holder and the shaft assembly, with multiple strands extending to the surface to ground the shaft assembly to the housing.

  • The system includes a rotor with a shaft assembly that rotates about an axis.
  • A housing supports the rotor for rotation.
  • A holder extends from the housing.
  • A ground assembly is held between the holder and the shaft assembly.
  • The ground assembly includes multiple strands that ground the shaft assembly to the housing.

Potential Applications

  • Electric motors
  • Generators
  • Wind turbines

Problems Solved

  • Ensures low impedance grounding
  • Prevents electrical malfunctions
  • Improves safety of electric machines

Benefits

  • Enhanced performance of electric machines
  • Increased reliability
  • Improved safety for operators and equipment


Original Abstract Submitted

An electric machine grounding system with low impedance includes a rotor that has a shaft assembly and that is configured to rotate about an axis. The shaft assembly has a surface. A housing supports the shaft assembly for rotation of the rotor. A holder extends from the housing. A ground assembly is held between the holder and the shaft assembly and includes a plurality of strands that extend to the surface to ground the shaft assembly to the housing.
