Advantages:
1) Higher Mechanical Strength: The slots provide additional mechanical support to the magnets, enabling the rotor to withstand higher centrifugal forces, making it suitable for medium- to high-speed applications.
2) Improved Magnet Protection: Partial embedding shields the magnets from external environmental factors like corrosion or impact, offering better durability compared to fully exposed SPM designs.
3) Cost-Effective Manufacturing: The manufacturing process is simpler than IPM rotors and achieves a balance between production complexity and performance.
4) Enhanced Thermal Management: The slots offer some level of thermal pathways, improving heat dissipation and reducing the risk of magnet demagnetization at higher temperatures.
This design strikes a balance between performance, mechanical strength, and cost, making it a practical choice for medium-performance applications like industrial motors and cost-sensitive EV systems.
