ELECTRIC MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18681228 titled 'ELECTRIC MOTOR

The abstract describes an outer rotor for a brushless DC electric motor, which includes a rotor body, a shaft for co-rotation, a cover, and a fan integrated with the cover as a single piece.

  • The outer rotor consists of a rotor body and a shaft that rotate together.
  • The cover surrounds the rotor body, providing protection and support.
  • The fan, integrated with the cover, has blades that induce airflow parallel to the rotational axis.
  • The design aims to improve cooling and efficiency of the electric motor.
  • This innovation simplifies the assembly process and enhances overall performance.

Potential Applications: - Electric vehicles - HVAC systems - Industrial machinery

Problems Solved: - Improved cooling of electric motors - Simplified assembly process - Enhanced efficiency and performance

Benefits: - Increased cooling efficiency - Simplified assembly and maintenance - Improved overall performance and longevity

Commercial Applications: - Electric vehicle manufacturing - HVAC system production - Industrial machinery development

Questions about the technology: 1. How does the integration of the fan with the cover improve the efficiency of the electric motor? 2. What are the specific advantages of using this outer rotor design in electric vehicles compared to traditional designs?


Original Abstract Submitted

An outer rotor for use with a brushless DC electric motor includes a rotor body, a shaft coupled for co-rotation with the rotor body and defining a rotational axis, a cover surrounding at least a portion of the rotor body, and a fan integrally formed with the cover as a single piece. The fan includes a plurality of blades extending radially outward of the cover and configured to induce an airflow along an exterior surface of the cover in a direction parallel with the rotational axis.
