ROTARY ELECTRIC MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18506728 titled 'ROTARY ELECTRIC MACHINE
Simplified Explanation: The patent application describes a rotary electric machine with improved cooling performance on one side of the winding part compared to the other side. This is achieved through a motor cooling passage in the stator's outer circumferential part, which includes different lengths of passages on each side of the center position.
- The motor cooling passage in the stator's outer circumferential part has circumferential direction parts with different lengths of passages on each side of the center position.
- The length of the passage on one side of the center position is longer than the length of the passage on the other side, resulting in higher cooling performance on that side.
Key Features and Innovation:
- Asymmetrical cooling design for improved performance.
- Motor cooling passage in the stator's outer circumferential part.
- Different lengths of passages on each side of the center position.
Potential Applications:
- Electric vehicles.
- Industrial machinery.
- Appliances.
Problems Solved:
- Uneven cooling of winding parts.
- Overheating issues in electric machines.
Benefits:
- Enhanced cooling efficiency.
- Increased reliability and lifespan of electric machines.
- Improved overall performance.
Commercial Applications: Electric Motor Cooling System Optimization for Enhanced Performance and Reliability
Questions about Electric Motor Cooling System Optimization: 1. How does the asymmetrical cooling design improve the performance of the electric machine? 2. What are the potential applications of this technology in different industries?
Frequently Updated Research: Research on advanced cooling techniques for electric machines to further enhance efficiency and reliability.
Original Abstract Submitted
To provide a rotary electric machine that the cooling performance of the winding part on the axial direction one side with connection can be higher than the cooling performance of the winding part on the axial direction other side with no connection. A motor cooling passage provided in an outer circumferential part of the stator is provided with circumferential direction parts that is provided with an one side circumferential direction passage and an other side circumferential direction passage; and circumferential direction parts that is provided with an axial direction passage, wherein a length of a part of the one side circumferential direction passage which exists on an upstream side of a center position of a total length of the motor cooling passage is longer than a length of a part of the other side circumferential direction passage which exists on the upstream side of the center position.
