Structural Features:
- Robust laminated steel stator construction
- High-energy samarium cobalt (SmCo) permanent magnets on rotor
- Precision ground shaft with keyway option available
- Integrated absolute encoder mounted on rear shaft end
- Sealed bearing design for contamination resistance
- Compact cylindrical form factor optimized for machine integration
Material Composition:
- Stator Core: Silicon steel laminations (0.35 mm thickness)
- Rotor Magnets: Samarium Cobalt (Sm2Co17)
- Shaft: Hardened alloy steel (AISI 4340)
- Housing: Aluminum alloy (6061-T6) with anodized finish
- Bearings: Sealed angular contact ball bearings (steel)
- Windings: Class H insulation (180°C rating), copper wire
Working Principle:
The motor operates on the principle of a three-phase permanent magnet synchronous motor (PMSM). The stator windings are energized by a servo drive (such as AKD series) producing a rotating magnetic field. The permanent magnet rotor locks to this rotating field, producing torque. The integrated single-turn absolute encoder provides position feedback to the drive for closed-loop servo control, enabling precise position, velocity, and torque regulation.
Functional Features:
- High torque-to-inertia ratio for fast dynamic response
- Single-turn absolute encoder eliminates homing requirement after power loss within one revolution
- Wide speed range from 0 to 4500 RPM
- Smooth cog-free operation at low speeds
- Compatible with Kollmorgen AKD, AKD-P, and AKD2G servo drives
Advantages:
- Exceptional torque density at 140 mm frame size
- Absolute position feedback removes need for reference homing on every power cycle
- High overload capacity (3:1 peak-to-continuous torque ratio)
- IP65 protection suitable for harsh industrial environments
- Low cogging torque for ultra-smooth motion at low speeds
Applicable Industries:
- CNC machining centers
- Packaging machinery
- Printing presses
- Robot joints (medium payload)
- Semiconductor equipment
- Textile machinery
Installation Requirements:
- Mount using standard NEMA or IEC flange pattern
- Ensure shaft alignment within 0.05 mm TIR
- Provide forced air cooling at minimum 2 m/s airflow
- Ground the motor housing to chassis ground
- Use shielded cable for encoder connection (max 50 m)
Usage Notes:
- Do not exceed rated continuous current of 12 A RMS per phase
- Verify encoder cable shield grounding at drive end only
- Operate within ambient temperature range of 0°C to 40°C
- Derate output by 1% per °C above 40°C ambient
