AI Technical Summary

⚠Technical Problem

The existing six-phase motor controller stacking structure cannot meet the layout requirements of twelve-phase motor controllers, and the cooling and wiring structure is messy, making it difficult to meet the requirements for efficient installation and cooling.

⚗Method used

The main housing is divided into an upper cavity and a lower cavity by a partition plate. Each group of six-phase motor controller assemblies is located on the outer surface of different water channels. Combined with HPD packaged SiC power modules and thin film capacitors, a unified wiring method is designed to increase cooling efficiency and simplify wiring layout.

🎯Benefits of technology

It achieves efficient cooling and unified wiring for the twelve-phase motor controller, meets layout requirements, and improves production efficiency and ease of installation.
