MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18513819 titled 'MOTOR

Simplified Explanation

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

• The motor includes a rotor and stator with a housing for protection.
• A first annular member seals the stator core and housing, with holes for refrigerant injection.
• The holes are strategically placed on different planes for efficient cooling and operation.

Potential Applications

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

Problems Solved

This technology addresses the issue of efficiently cooling the motor during operation, which can improve performance and longevity. The seal provided by the annular member also helps protect the internal components from external elements.

Benefits

The benefits of this technology include improved cooling efficiency, increased motor performance and reliability, extended lifespan of the motor, and enhanced overall system efficiency.

Potential Commercial Applications

Potential commercial applications of this technology include electric vehicles, refrigeration systems, air conditioning units, industrial pumps, and other electric motor-driven equipment.

Possible Prior Art

One possible prior art for this technology could be similar motor designs with seals and cooling mechanisms, but the specific configuration and placement of the annular member and holes for refrigerant injection may be unique to this patent application.

How does this technology compare to existing motor cooling systems in terms of efficiency and effectiveness?

This article does not provide a direct comparison with existing motor cooling systems, so it is unclear how this technology stacks up against current industry standards.

What are the potential challenges or limitations of implementing this technology in different types of electric motors?

The article does not address any potential challenges or limitations that may arise when implementing this technology in various electric motor systems, leaving room for further exploration and analysis in this area.

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.
