Kollmorgen AKM65K-ANCNR-00
Product Introduction:
The AKM65 is one of the largest standard AKM frames (135 mm square flange), intended for high-power machine tool, converting, and heavy automation applications. “K” stack is a long laminate giving high continuous torque. “ANCNR-00” = Standard configuration, N=Std seal (IP65), C=Resolver feedback, N=No brake, R=Right-angle or standard connector orientation, 00=default shaft (smooth / plain).
Detailed content

-
Shaft: 24 mm diameter, smooth/plain (no keyway per “R” option)
-
Feedback: 2-pole resolver (16-bit interpolation capable in AKD)
-
Connector: 2 × M23 angled rotatable Speed Tec connectors (power + resolver)
-
Degree of Protection: IP65 (with cable glands)
-
Insulation Class: F (155 °C), with PTC thermistor
-
Flange: 138 × 138 mm IEC square flange, pilot Ø110 mm
-
Weight: ~12–14 kg (frame dependent)
Material & Construction:
-
Stator: Heavy-section copper winding, Class F insulation system
-
Rotor: High-energy NdFeB magnets, retaining ring secured
-
Housing: Cast / extruded aluminum with machined flange
-
Shaft: Alloy steel, dynamically balanced to G2.5 or better
-
Bearings: Deep-groove ball bearings, greased-for-life
Installation & Notes:
-
Requires secure mounting with ≥4 M10 bolts torqued to spec
-
Resolver must be phased correctly during first auto-commissioning in AKD (WorkBench will detect polarity)
-
Large inertia — check regeneration requirements under frequent deceleration
-
Use appropriately sized power cabling; observe bending radius for M23 connectors
