Kollmorgen R65GMNA-R2-NS-NV-00
Product Brief:
The R65GMNA-R2-NS-NV-00 is a servo motor from Kollmorgen’s R-Series product line. The model number decodes as: R65 = frame size 65 mm, G = general purpose, M = metric, N = specific winding, A = variant, R2 = revision 2, NS = no shaft seal (or specific seal type), NV = no vacuum compatibility, 00 = base configuration. This motor is designed for general industrial automation and OEM integration.

Functional Features:
- Compact 65 mm frame — smaller than standard NEMA 23, ideal for space-constrained designs
- Incremental encoder — 2500 pulses/revolution, A/B/Z channels
- Low cogging torque — smooth low-speed performance
- High speed capability — up to 6000 RPM continuous
- Cost-optimized — general-purpose motor for volume applications
Material Composition:
- Housing: Aluminum alloy (die-cast)
- Stator: Silicon steel laminations (0.35 mm)
- Rotor: Sintered NdFeB magnets
- Shaft: Carbon steel, chrome-plated
- Bearings: Sealed ball bearings (NSK or equivalent)
Structural Features:
- 65 mm cylindrical body
- 10 mm keyed shaft with single shaft seal
- M12 connector for encoder
- Screw terminal block for power
- 2-bolt or 4-bolt flange mount option
Operating Principle:
Sinusoidal brushless commutation. The AKD servo drive sends three-phase sinusoidal currents to the stator windings based on rotor position from the incremental encoder. The permanent magnet rotor produces torque proportional to the q-axis current component.
Advantages:
- Small footprint — fits in tight spaces where NEMA 23 is too large
- High speed — 6000 RPM in a compact package
- Low cost — optimized for high-volume OEM applications
- Easy integration — standard AKD drive compatibility
Applicable Industries:
- Pick-and-place machines
- Small robot joints
- Laboratory equipment
- Textile machines (spindle drives)
- Conveyor rollers
- AGV/AMR wheel drives
Installation Requirements:
- Mount with 2-bolt or 4-bolt flange, torque to 3 Nm
- Shaft coupling: use flexible coupling, max 0.1 mm misalignment
- Cable routing: keep encoder cable away from power cables (min 50 mm)
- Ground motor housing to drive chassis
Usage Notes:
- Incremental encoder requires homing after each power cycle
- Do not exceed 6000 RPM — mechanical limit of bearings
- IP54 rating — protect from direct water jet
- Operating temperature must not exceed 40°C ambient
