II. Key Highlights
1. High Torque + Wide Voltage: Low KV value adapts to low-speed precision control; max torque up to 0.35Nm, can replace motors like 4010/4008, covering multi-voltage application scenarios.
2. Structural Advantages: CNC alloy housing + hollow shaft design, balancing structural strength and installation flexibility; low cogging torque ensures smooth operation.
3. Strong Expandability: Supports optional magnetic encoders and FOC drivers, suitable for power demands of heavy-load and precision equipment.
