MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240178719 titled 'MOTOR

Simplified Explanation

The patent application describes a motor with a rotor, stator, housing, and annular member for sealing and refrigerant injection.

• The motor includes a rotor, stator, housing, and annular member.
• The annular member seals between the stator core and housing.
• The annular member has holes for injecting refrigerant towards the coil end.
• The holes are located on different planes perpendicular to the axis.

Potential Applications

The technology described in the patent application could be applied in various electric motor systems, such as HVAC systems, industrial machinery, and automotive applications.

Problems Solved

This technology solves the problem of effectively sealing the stator core within the housing while also providing a means for injecting refrigerant towards the coil end for cooling purposes.

Benefits

The benefits of this technology include improved efficiency and performance of the motor due to better cooling of the coils, increased longevity of the motor components, and potentially reduced maintenance requirements.

Potential Commercial Applications

The technology could find commercial applications in industries such as HVAC, automotive, and manufacturing, where electric motors are used extensively. The section title could be "Innovative Motor Technology for Enhanced Performance in HVAC and Automotive Industries".

Possible Prior Art

One possible prior art could be the use of separate seals and refrigerant injection systems in electric motors, which may not be as integrated and efficient as the system described in this patent application.

Unanswered Questions

How does the design of the annular member impact the overall efficiency of the motor system?

The efficiency of the motor system could be affected by factors such as the material of the annular member, the size and placement of the holes for refrigerant injection, and the overall design of the sealing mechanism.

Are there any potential challenges in implementing this technology in existing motor systems?

Implementing this technology in existing motor systems may require modifications to the design and manufacturing processes, as well as potential compatibility issues with older systems. Additionally, ensuring proper alignment and sealing of the annular member within the housing could be a challenge during installation.

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 have a cylindrical shape about an axis of the stator core. the first annular member may include at least one first hole and at least one second hole through which refrigerant is injected toward a first coil end. the at least one first hole may be located on a first plane perpendicular to the axis. the at least one second hole may be located on a second plane that is perpendicular to the axis and spaced apart from the first plane in the axial direction.
