Material Composition:
- Housing: Aluminum alloy, black anodized
- Shaft: Hardened stainless steel
- Magnets: NdFeB N42
- Windings: Class H insulation, copper
- Bearings: Sealed ball bearings
Structural Features:
- 57 mm diameter compact body — fits in tight spaces
- Rear-mounted connector (M12 or M23 depending on sub-variant)
- Keyed shaft, 8 mm — standard for small couplings
- IP40 rating — protected against solid objects >1 mm, no water protection
Working Principle:
3-phase electronic commutation via AKD servo drive. Incremental encoder provides position/velocity feedback. The drive commutates stator phases based on encoder position to produce continuous torque.
Advantages:
- Compact 57 mm frame — ideal for space-constrained applications
- Direct AKD compatibility — plug-and-play with AKD-P/AKD-B drives
- Low inertia — fast acceleration response
- Cost-effective — economy-class servo motor
Applicable Industries:
Small robotics, medical devices, lab automation, valve actuators, small conveyors, pick-and-place, 3D printers, textile machines
Series: AKM57 (57 mm frame, 0.85 Nm) — OEM/legacy variant
Installation Requirements:
- Flexible coupling — misalignment: <0.05 mm, <0.1°
- Shielded cable, max 10 m
- Ground chassis to PE
- Do not exceed 4500 RPM
Usage Notes:
- IP40 only — do not use in wet or dusty environments without additional protection
- Encoder cable bend radius: minimum 30 mm
- Do not apply axial loads >30 N on shaft
- Compatible with AKD-P00606-NAC and AKD-B00606-NCA drives (6A class)
