ELECTRIC MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18504643 titled 'ELECTRIC MOTOR

Simplified Explanation

The electric motor described in the patent application includes a stator with a supply hole, a first flow passage, and second flow passages. The first flow passage extends along the circumferential direction of the stator, while the second flow passages extend along the stator's axis and intersect the first flow passage. Guides are placed in the first flow passage to disrupt the flow of refrigerant, which is supplied through the supply hole. The disrupted refrigerant flows into the second flow passages, ensuring even distribution and effective cooling of the entire stator.

• Stator with supply hole, first flow passage, and second flow passages
• Guides in the first flow passage disrupt refrigerant flow
• Refrigerant is evenly distributed into the second flow passages for effective cooling

Potential Applications

The technology described in the patent application could be applied in various electric motor systems where efficient cooling is essential, such as electric vehicles, industrial machinery, and HVAC systems.

Problems Solved

This innovation addresses the challenge of uneven cooling in electric motors, ensuring that the stator is effectively cooled to prevent overheating and potential damage to the motor.

Benefits

- Improved cooling efficiency - Enhanced motor performance and longevity - Reduced risk of overheating and motor failure

Potential Commercial Applications

The technology could be utilized in electric vehicle motors, industrial machinery, and air conditioning systems to improve overall performance and reliability.

Possible Prior Art

Prior art related to the cooling of electric motors may include traditional cooling methods such as air cooling or liquid cooling systems. However, the specific design of the stator with multiple flow passages and guides to disrupt refrigerant flow may be a novel approach in this field.

How does this technology compare to other cooling methods for electric motors?

The article does not provide a direct comparison with other cooling methods such as air cooling or liquid cooling systems. Further research or testing may be needed to evaluate the efficiency and effectiveness of this technology in comparison to existing methods.

What are the potential limitations or drawbacks of this cooling system?

The article does not mention any potential limitations or drawbacks of this cooling system. It would be important to investigate factors such as maintenance requirements, cost-effectiveness, and compatibility with different motor designs to fully assess the technology's practicality and feasibility.

Original Abstract Submitted

An electric motor disclosed herein may include a stator, a supply hole, a first flow passage, and second flow passages. The first flow passage and the second flow passages may be provided in the stator. The first flow passage may extend along a circumferential direction of the stator. The second flow passages may extend along an axis of the stator and cross the first flow passage. A plurality of guides may be provided in the first flow passage to disturb a flow of refrigerant. The refrigerant is supplied from the supply hole to the first flow passage and disturbed by the guides. A part of the refrigerant of which flow is disturbed flows into the second flow passages. The refrigerant is distributed, thus, the refrigerant flows evenly into the second flow passages. The entire stator is thus effectively cooled.
