Kollmorgen AKM54K-ANC2AA00 12.85 Nm Servo Motor

Key Technical Specifications

Trade documentation specifically identifies AKM54K-ANC2AA00 with 640 VDC, 4,000 rpm, 12.85 Nm, 8.7 A, and 3.23 kW.

A secondary technical listing gives a 108 mm square flange and describes the feedback as a 2-pin resolver. Because this information is not corroborated by an accessible Kollmorgen primary datasheet for the exact suffix, the mechanical dimensions should be confirmed from the motor nameplate/drawing before replacement.

Product Introduction

The Kollmorgen AKM54K-ANC2AA00 is a high-torque AKM-series permanent-magnet synchronous servo motor intended for industrial motion-control applications. Available documentation identifies the exact model as a resolver-feedback motor and associates it with a 640 VDC-class drive system. Trade records also identify applications involving conveyor transport mechanisms.

The available exact-model data indicates approximately 12.85 Nm torque, 4,000 rpm, 8.7 A, and 3.23 kW. The motor’s complete suffix should be matched before substitution because resolver configuration, shaft design, connectors, and brake options vary across the AKM54K family.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation (~10 min)

1. Record the complete motor nameplate: .
2. Confirm the replacement has the same winding, resolver feedback, shaft, and connector configuration.
3. Verify the servo amplifier is rated for the applicable 640 VDC-class motor bus.
4. Back up the existing drive parameters and axis configuration.
5. Check the motor mounting dimensions and coupling before removing the existing unit.

⚠️ Do not select the replacement solely by frame designation. The complete suffix defines important electrical and mechanical characteristics.

Stage 2 — Removing the Old Motor (~5 min)

1. Place the machine in its approved maintenance state.
2. Disconnect incoming power and verify the servo DC bus has fully discharged.
3. Secure the mechanical load against unexpected movement.
4. Label the motor power and resolver connections.
5. Disconnect the motor connectors only after confirming zero hazardous voltage.
6. Remove the coupling and mounting fasteners.
7. Inspect the coupling, shaft, flange, and connectors for wear or damage.

⚠️ A 640 VDC-class servo system can retain hazardous energy after power removal. Follow the drive manufacturer’s discharge and lockout procedure.

Stage 3 — Installing the New Motor (~5 min)

1. Compare the replacement nameplate with the removed motor.
2. Confirm the keyed shaft and mechanical coupling are compatible.
3. Inspect the motor flange and shaft before installation.
4. Install the motor without striking the shaft or applying excessive radial load.
5. Align the coupling according to the machine manufacturer’s specification.
6. Secure the motor using the specified mounting hardware and torque.
7. Connect the motor power and resolver cables to the correct drive connections.
8. Ensure the angular connectors are properly oriented and mechanically supported.

Stage 4 — Power-On & Testing (~10–15 min)

1. Restore power after confirming the mechanical installation is complete.
2. Verify the drive recognizes valid resolver feedback.
3. Confirm the configured motor data corresponds to .
4. Check feedback position at zero speed.
5. Perform a low-speed jog with the machine unloaded where practical.
6. Verify motor direction.
7. Monitor current, following error, vibration, and abnormal noise.
8. Gradually increase operating speed after the initial test passes.
9. Record the final drive parameters and commissioning results.

FAQ

What is the Kollmorgen -ANC2AA00?

It is an AKM-series synchronous servo motor from Kollmorgen/Danaher Motion. The exact model is listed in Danaher Motion catalogs as a synchronous servo motor, and trade records identify it as a high-power motor used in industrial machinery.

What are the main ratings of -ANC2AA00?

Available exact-model trade data gives approximately 12.85 Nm, 4,000 rpm, 8.7 A, 3.23 kW, and 640 VDC. These figures should be checked against the physical nameplate before commissioning because marketplace data can contain configuration errors.

What feedback does -ANC2AA00 use?

Available specialist documentation identifies the exact configuration as a resolver-feedback motor, with one technical listing specifying a 2-pin resolver.

Does this motor have a brake?

The available exact-model configuration data indicates no integrated holding brake. Do not assume a brake can be added without checking the Kollmorgen configuration and mechanical assembly.

Is AKM54K-ANC2AA00 a 640 VDC motor?

The trade specification for this exact part number identifies 640 VDC and 4,000 rpm. This should be understood as the associated DC-bus/drive electrical reference rather than connecting 640 VDC directly to the motor phases.

Can I replace it with another ?

Not automatically. variants can differ in winding, feedback, shaft, connector, brake, and sealing configuration. Match the entire part number and verify the servo amplifier’s motor database parameters before installation.

What should I verify before purchasing a replacement?

At minimum, compare the com nameplate, winding code, resolver arrangement, shaft/keyway, connector orientation, brake configuration, and rated electrical data. A clear photograph of the motor nameplate is useful when sourcing legacy or surplus inventory. Lektronix also lists the exact model as a Kollmorgen servo motor and offers repair, new, refurbished, and exchange options, indicating that condition should be specified separately when purchasing.
