FANUC A06B-0061-B203 AC Servo Motor | 0.5 kW 4000 RPM 3-Phase Servo Motor

Product Overview

The FANUC A06B-0061-B203 AC Servo Motor is a compact, high-response motion control solution built for CNC machinery, automated production equipment, and precision industrial systems that demand stable torque delivery and accurate positioning. With its 0.5 kW output, 4000 RPM speed, and 3-phase 200–240 V input, this motor is well suited for applications where consistent servo performance and dependable replacement compatibility are essential.

Designed for installed FANUC systems that require reliable feedback and secure mechanical coupling, this model combines a straight keyed shaft with β128iA feedback and a compact servo structure that fits small-to-medium motion axes effectively. For buyers sourcing a replacement motor for existing equipment, it offers a practical balance of speed, torque, and integration confidence.

Technical Data

Performance and Application

In real-world industrial use, the A06B-0061-B203 is a strong fit for machine builders and maintenance teams that need precise servo motion without unnecessary complexity. Its 4000 RPM capability supports fast axis response, while the 2 N·m torque rating helps provide stable control in compact machine assemblies. Because this motor is commonly associated with smaller FANUC servo applications, it is especially useful where space efficiency and accurate motion are just as important as raw output.

This model is commonly considered for:

• CNC machine tools

• Compact automated motion systems

• Industrial equipment repair and maintenance

• Servo replacement projects in FANUC-based machinery

• Spare parts inventory for fast service response

Its straight keyed shaft supports secure coupling in compatible assemblies, and the β128iA feedback configuration helps maintain the level of control accuracy expected in precision motion systems. That makes it a practical choice for users who want to restore machine performance with a matching servo motor rather than settle for a loosely comparable substitute.

Why Choose FANUC A06B-0061-B203

When a servo motor fails, the priority is rarely just finding a similar part. It is finding a motor that matches the installed system closely enough to protect machine accuracy, shorten downtime, and reduce integration risk. The A06B-0061-B203 stands out because its core specifications are clearly tied to the βiS 2/4000 platform, giving buyers a more confident basis for replacement planning.

For service teams, resellers, and plant operators, that matters. A motor with the correct output level, shaft format, and feedback type can make the difference between a smooth restart and a time-consuming compatibility problem. This is why the A06B-0061-B203 remains a valuable option for maintaining established FANUC-controlled equipment.

FAQ

Q1: What is the FANUC A06B-0061-B203 used for?

A: The FANUC A06B-0061-B203 is an AC servo motor typically used in CNC machines, compact industrial automation systems, and precision motion control equipment. It is commonly selected as a replacement motor in FANUC-based machinery where stable servo response, accurate positioning, and reliable system matching are important.

Q2: What are the main specifications of the A06B-0061-B203?

A: This model is generally identified as βiS 2/4000 and is associated with 0.5 kW output, 2 N·m stall torque, 3.3 A stall current, 4000 RPM, 3-phase 200–240 V AC input, 8 poles, Class F insulation, a straight keyed shaft, and β128iA feedback. These are the main technical points buyers usually verify before replacement.

Q3: Does the A06B-0061-B203 have a brake?

A: Available product references for A06B-0061-B203 describe it as a no-brake motor. This matters during replacement because brake and non-brake versions are not interchangeable in every application. Buyers should always confirm the installed machine configuration before ordering.

Q4: What should be checked before buying this servo motor?

A: Before purchasing, it is best to confirm the part number, motor model, output rating, speed, shaft type, feedback type, and whether the machine requires a brake or non-brake version. Matching these points helps avoid wiring, mounting, or performance issues after installation.

Q5: Is the A06B-0061-B203 a good option for spare inventory?

A: Yes. For facilities that already operate compatible FANUC systems, keeping the A06B-0061-B203 in spare stock can reduce downtime and improve maintenance response. Because servo motor failures can halt production quickly, having a correctly matched replacement available is often a smart inventory decision.
