MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240162765 titled 'MOTOR

Simplified Explanation

The patent application describes a motor with a rotor, stator, housing, and annular member for sealing and injecting refrigerant towards the coil.

• The motor includes a rotor, stator, housing, and annular member.
• The annular member seals between the stator core and housing, with holes for refrigerant injection.
• The holes include a large hole and a small hole, with the small hole having a smaller opening area.

Potential Applications

This technology could be applied in various electric motor systems that require efficient cooling and sealing mechanisms, such as HVAC systems, electric vehicles, and industrial machinery.

Problems Solved

This innovation addresses the challenge of maintaining optimal operating temperatures in electric motors by providing a reliable seal and efficient refrigerant injection system.

Benefits

The motor design with the annular member allows for improved cooling efficiency, longer motor lifespan, and enhanced overall performance due to better temperature regulation.

Potential Commercial Applications

This technology could be utilized in the development of advanced electric motors for various industries, including automotive, aerospace, and manufacturing, to enhance energy efficiency and reliability.

Possible Prior Art

One possible prior art could be the use of seals and cooling systems in electric motors to prevent overheating and improve performance. However, the specific design of the annular member with different hole sizes for refrigerant injection may be a novel aspect of this innovation.

Unanswered Questions

How does the size of the small hole affect the refrigerant injection process?

The patent application mentions a small hole with a smaller opening area than the large hole, but it does not elaborate on how this size difference impacts the refrigerant injection towards the coil.

What materials are used in the construction of the annular member for optimal performance?

The patent application does not specify the materials used in the annular member, which could be crucial for its durability, compatibility with refrigerants, and overall effectiveness in sealing and cooling the motor.

Original Abstract Submitted

a motor may include a rotor; a stator comprising a stator core and a coil; a housing that houses the rotor and the stator; and a first annular member that provides a seal between a first end face of the stator core in an axial direction of the stator core and an inner wall surface of the housing. the first annular member may include a plurality of first holes through which refrigerant is injected toward a first coil end of the coil protruding from the first end face of the stator core. the plurality of first holes may include a first large hole and a first small hole, and the first small hole may have an opening area smaller than an opening area of the first large hole.
