MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18501162 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, 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 where efficient cooling and sealing are required, such as in HVAC systems, electric vehicles, and industrial machinery.
Problems Solved
This innovation solves the problem of effectively sealing the stator core within the housing while also providing a means for injecting refrigerant to cool the motor during operation.
Benefits
The benefits of this technology include improved motor efficiency, longer lifespan due to better cooling, and reduced maintenance requirements.
Potential Commercial Applications
Potential commercial applications for this technology include electric vehicle motors, HVAC systems, industrial machinery, and other electric motor-driven devices.
Possible Prior Art
One possible prior art for this technology could be patents related to motor cooling systems and sealing mechanisms in electric motors.
Unanswered Questions
How does this technology compare to existing motor cooling and sealing methods in terms of efficiency and cost-effectiveness?
This article does not provide a direct comparison with existing motor cooling and sealing methods, so it is unclear how this technology stacks up against current practices.
Are there any limitations or drawbacks to using this specific annular member design for sealing and refrigerant injection in motors?
The article does not address any potential limitations or drawbacks of using this specific annular member design, leaving room for further exploration into its practicality and effectiveness in real-world applications.
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.
