KOLLMORGEN AKM34H-ANC2R-00 Servo Motor – Compact, high-response torque for precise machine axes

The KOLLMORGEN AKM34H-ANC2R-00 is part of the AKM series of brushless synchronous servomotors known for high torque density and smooth, low-cogging performance. From my experience, this configuration typically suits 230/400 VAC-class servo systems and pairs seamlessly with KOLLMORGEN AKD and AKD2G drives. You might notice that the “34” points to a size-3 frame with a longer stack for added torque, while the “H” winding seems to balance speed capability and continuous torque in many cases.

Key Features

• High torque density – The AKM34 length stack delivers strong continuous torque in a compact footprint, ideal when cabinet space is tight.
• Smooth, precise motion – Low cogging and optimized magnetic design help achieve stable speed regulation for indexing, sealing, or pick-and-place axes.
• Flexible feedback options – This build is configured for common AKM feedback interfaces; it typically aligns with AKD/AKD2G drives for quick commissioning.
• Industrial-grade sealing – When mated with correct connectors and a shaft seal option, AKM motors reach robust ingress protection for shop-floor environments.
• Wide drive compatibility – Works with KOLLMORGEN AKD single-axis and AKD2G dual-axis drives across 120/240/480 VAC systems (exact bus depends on the drive).
• Global support & lifecycle – AKM is a long-running platform, which in many cases simplifies spares management and reduces downtime risk.

Technical Specifications

Note: The “N” in ANC2R typically indicates no holding brake on this variant; final features should be confirmed against the nameplate and Kollmorgen build sheet.

Application Fields

• Packaging & converting machines – Repeatable torque for seal jaws, knife stations, and feed rollers where cycle-time matters.
• Electronics assembly – Precise positioning on small gantries and screwdriving axes with tight tact times.
• Printing & labeling – Smooth low-speed control for web tension and registration tasks.
• Machine tools & automation – Auxiliary axes, tool changers, and index tables requiring fast acceleration.
• Medical and test devices – Compact footprint where low vibration and accuracy are important.

Advantages & Value

• Reliability you can plan around – AKM motors are widely deployed; spare availability and field familiarity reduce downtime.
• Compatibility – Native pairing with AKD/AKD2G drives cuts commissioning time; feedback and cable sets are standardized.
• Cost of ownership – High efficiency and right-sized torque typically let you use smaller drives and cables, saving panel space.
• Engineering support – Drive sizing tools and parameter libraries streamline replacement of legacy axes.

Installation & Maintenance

• Mounting: Use the pilot and flange holes; align couplings to minimize shaft side load. A torque wrench is recommended for repeatable fits.
• Cabinet/drive environment: Provide adequate ventilation for the drive; shield motor and feedback cables, ground at the drive side to reduce EMI.
• Wiring: Use Kollmorgen power/feedback cable sets; route power and feedback separately where possible. Verify phase sequence and insulation resistance.
• Safety: Lock out power before handling connectors; wait for DC bus capacitors to discharge on the drive.
• Routine care: Inspect connectors and cable strain relief quarterly; keep motor body free of oil buildup; firmware/parameter backups on the drive help recovery.
• Calibration: If using resolver/encoder, run the drive’s commutation/phase identification procedure after installation or motor replacement.

Quality & Certifications

• Conformity: CE and UKCA typically applicable; RoHS compliant
• Safety: UL Recognized components (varies by exact build)
• Manufacturing: Built under ISO 9001 quality systems
• Warranty: 12 months (365 days) from shipment

Recommended Supporting Components

• KOLLMORGEN AKD or AKD2G servo drives – Single or dual-axis; select voltage class to match your mains (120/240/480 VAC).
• Power and feedback cable sets – Factory-terminated cables in standard lengths (e.g., 3 m / 5 m / 10 m) reduce wiring errors.
• Precision couplings or gearheads – Match shaft size and required backlash; KOLLMORGEN gearheads or equivalent precision planetary types work well.
• EMI filters and braking resistors – As required by the drive sizing and application duty cycle.

If you share your target torque/speed, supply voltage, and cycle profile, I can help validate drive sizing and confirm whether this AKM34H-ANC2R-00 build’s feedback and sealing options match your environment. In most cases, this model drops in smoothly where a compact, mid-range AKM axis is needed.
