Structural Features:

• Stator: Laminated silicon steel, epoxy-potted for environmental protection
• Rotor: Rare-earth permanent magnets (NdFeB), dynamically balanced
• Bearings: Two sealed ball bearings (lifetime-lubricated)
• Housing: Aluminum alloy, anodized finish

Functional Characteristics:

• Integrated absolute encoder eliminates homing routine after power loss
• Hiperface DSL interface provides high noise immunity for industrial environments
• CNC variant includes Z-channel index pulse for reference mark alignment
• High torque-to-inertia ratio for fast dynamic response

Applicable Industries:

• CNC machining centers
• Robot joints (6-axis and collaborative)
• Packaging machinery
• Semiconductor handling equipment
• Medical devices

Key Advantages:

• No external encoder cable required — reduces installation complexity
• Absolute position retention eliminates recalibration
• Compact form factor with high power density
• Robust construction for continuous duty operation

Installation Requirements:

• Mount using M5 tapped holes on flange (bolt pattern: 80 mm diameter)
• Ensure shaft alignment within 0.05 mm TIR
• Torque mounting bolts to 2.5 Nm
• Ground motor housing to chassis ground

Usage Notes:

• Do not exceed maximum continuous current rating
• Ensure adequate ventilation; derate torque by 10% above 40°C ambient
• Use shielded cable for encoder signals in high-EMI environments
