Core Advantages

1. Extra large Φ50.8 outer rotor structure supports ultra-high peak power up to 2843W for super heavy payload;
2. Single 380KV low-speed high-torque winding perfectly matches 8S high-voltage lithium battery packs;
3. 14AWG thick high-temperature wire effectively suppress temperature rise under long heavy load;
4. 12N14P multi-pole design brings ultra-smooth rotation, low vibration and high energy conversion efficiency;
5. Heavy-duty M6 threaded shaft and reinforced 4×M4 mounting base resist large impact thrust;
6. Long 500mm outgoing wire simplifies wiring layout for large industrial automation equipment.
