AI Technical Summary
Technical Problem
Rotating electric machines face challenges in miniaturization and increased manufacturing costs due to separate coolant tanks and terminal holders, which complicate the structure and require additional components.
Method used
Integration of a terminal holding member and refrigerant tank, formed as a single unit, with a storage section for refrigerant that cools the machine, allowing refrigerant to flow through holes for efficient cooling.
Benefits of technology
Enables easy miniaturization and reduces manufacturing costs by eliminating the need for separate installations, facilitating easier manufacturing.
