ROTOR ASSEMBLY FOR AN ELECTRIC MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240030765 titled 'ROTOR ASSEMBLY FOR AN ELECTRIC MOTOR

Simplified Explanation

The abstract describes a rotor assembly that includes a shaft with a lubricant inlet channel and a lamination stack. The lamination stack is rotatably coupled to the shaft and has a lubricant cooling channel in fluid communication with the lubricant inlet channel. The assembly also includes first and second end caps adjacent to the ends of the lamination stack. One of the end caps defines an end cap inlet, a lubricant outlet channel, and an end cap outlet.

  • The rotor assembly includes a shaft with a lubricant inlet channel and a lamination stack.
  • The lamination stack is rotatably coupled to the shaft and has a lubricant cooling channel.
  • The assembly also includes first and second end caps adjacent to the ends of the lamination stack.
  • One of the end caps has an end cap inlet, a lubricant outlet channel, and an end cap outlet.

Potential applications of this technology:

  • This rotor assembly can be used in various rotating machinery such as motors, generators, and turbines.
  • It can be applied in automotive engines, wind turbines, and industrial machinery.

Problems solved by this technology:

  • The lubricant cooling channel helps to dissipate heat generated during operation, preventing overheating and potential damage to the rotor assembly.
  • The lubricant inlet and outlet channels ensure proper lubrication of the assembly, reducing friction and wear.

Benefits of this technology:

  • Improved cooling of the rotor assembly increases its efficiency and extends its lifespan.
  • Proper lubrication reduces friction, leading to smoother operation and reduced maintenance requirements.
  • The design allows for easy access to the lubricant inlet and outlet, simplifying maintenance and servicing.


Original Abstract Submitted

a rotor assembly includes a shaft defining a lubricant inlet channel for receiving a lubricant and a lamination stack. the lamination stack is rotatably coupled to the shaft, extends between first and second lamination stack ends, and defines a lubricant cooling channel in fluid communication with the lubricant inlet channel. the rotor assembly also includes a first end cap adjacent to the first lamination stack end and a second end cap adjacent to the second lamination stack end. one of the first end cap and the second end cap defines an end cap inlet at a first radial distance from the shaft, a lubricant outlet channel defined to extend at least partially radially inward toward the shaft, and an end cap outlet at a second radial distance from the shaft which is less than the first radial distance for expelling the lubricant.
