Structural Features: Compact cylindrical form factor with 130mm flange diameter. The motor features an integrated SFD feedback device, a 0.5m shielded cable with IP65 connector for power and feedback signals, and a standard shaft without keyway. The modular stack design allows multiple stack lengths within the same frame size to match torque requirements.
Working Principle: The motor operates as a three-phase permanent magnet synchronous motor (PMSM). The stator contains a three-phase winding distributed across precision-laminated silicon steel slots. When energized by a sinusoidal current from the servo drive, the rotating magnetic field interacts with the permanent magnet rotor to produce continuous torque. The SFD feedback device provides real-time rotor position and speed information to the drive, enabling closed-loop vector control with precise torque, speed, and position regulation.
Installation Requirements:
- Mount using standard IEC/NEMA flange mounting holes on the AKM4 frame
- Ensure proper alignment between motor shaft and load to minimize radial and axial forces
- Use shielded motor cables with correct grounding to reduce EMI
- Maintain adequate clearance around the motor housing for natural convection cooling
- Connect the motor cable to the AKD drive X2 (power) and X10 (feedback) interfaces
Usage Precautions:
- Verify the motor winding matches the drive voltage configuration before commissioning
- Do not exceed the rated continuous torque at 40°C ambient temperature
- Monitor motor temperature during high-duty-cycle operation
- Use Kollmorgen WorkBench software for parameter configuration and auto-tuning
- Ensure the SFD feedback cable is properly shielded and grounded
- Avoid exposure to silicone oil contamination in the operating environment
