New FANUC A06B-0247-B100 AC Servo Motor for CNC and Industrial Motion Systems

The FANUC A06B-0247-B100 AC Servo Motor is designed for CNC equipment and industrial automation systems that rely on precise motion control, steady servo response, and dependable long-term operation. In real production environments, the right servo motor is not judged by output alone. It also needs to deliver smooth acceleration, predictable axis behavior, and consistent motion quality under changing loads. That is where this motor stands out, making it a practical fit for machine tools, automated manufacturing lines, and professional replacement projects.

Key Technical Data

Built for Precision Where Motion Quality Matters

In CNC and automation applications, servo performance is measured by control quality as much as by raw force. A motor must follow command changes cleanly, hold steady when load conditions shift, and maintain repeatable axis behavior over long duty cycles. The A06B-0247-B100 fits this type of requirement well because its output and torque profile are matched to systems where stable motion is essential to productivity and part quality.

Its 22 Nm stall torque provides solid low-speed control and dependable acceleration, while the 64 Nm maximum torque gives useful reserve during short-duration peak demand. For practical machine operation, that means the motor can support responsive motion without sacrificing servo stability. In high-precision environments, that balance is often more valuable than simply choosing a larger motor, because the goal is not only to move the axis, but to move it accurately and consistently.

Straight-Shaft Design for Easier Mechanical Compatibility

Replacement success depends heavily on mechanical fit. This model is widely described with a straight shaft, and several sources also use the SLK shaft detail, which is a useful installation reference when comparing it with an existing motor. Correct shaft style helps simplify coupling alignment, reduce retrofit complications, and improve the likelihood of restoring the machine’s original motion characteristics after installation.

For maintenance teams and rebuilders, that can make a real difference. A motor that matches the original shaft arrangement is usually easier to install and commission, especially in established FANUC-based systems where mechanical layout and servo tuning are already optimized around the original configuration.

Accurate Feedback for Stable Servo Control

This motor is also commonly associated with A1000 or αiA1000 pulsecoder feedback. In servo systems, encoder feedback is what allows the control to monitor speed and position continuously, which is essential for smooth correction, repeatable movement, and accurate axis response. When the correct feedback type is matched to the control system, the machine has a much better chance of preserving its intended motion behavior after replacement.

That matters especially in CNC machinery, where even small deviations in motion can affect machining consistency, cycle quality, or surface finish. Rather than being just a replacement component, the motor serves as a central part of the machine’s motion-control accuracy and daily reliability.

Typical Applications

The FANUC A06B-0247-B100 AC Servo Motor is commonly considered for:

• CNC machine tools

• Industrial automation systems

• Precision axis control assemblies

• Motion-control equipment

• Compatible FANUC servo motor replacement projects

FAQ

Q1: What is the rated output of the FANUC A06B-0247-B100?
A1: The FANUC A06B-0247-B100 is commonly listed with a rated output of 4.0 kW. This gives it enough capacity for CNC and industrial automation systems that need reliable servo performance without moving into a much larger motor frame. In day-to-day use, that output level supports stable axis movement, predictable control behavior, and solid overall motion performance in precision equipment.

Q2: What speed and torque performance is associated with this motor?
A2: FANUC αi-series specification data for the A06B-0247-B□0□ motor family lists 3000 min⁻¹ rated speed, 3000 min⁻¹ maximum speed, 22 Nm stall torque, and 64 Nm maximum torque. These figures indicate a motor intended for controlled servo work where accurate response, stable acceleration, and dependable load handling are important. For buyers evaluating compatibility, those are some of the most useful core performance values to compare with the installed motor.

Q3: What shaft and feedback configuration is commonly listed for the A06B-0247-B100?
A3: Public distributor listings commonly describe this model with a straight shaft and A1000 / αiA1000 feedback. Some sources also specify the shaft detail as SLK. These points matter because they affect both mechanical installation and control-side compatibility. Confirming them early can reduce replacement issues and help preserve the machine’s original motion characteristics.

Q4: What electrical characteristics are commonly listed for this motor?
A4: Available listings commonly associate the A06B-0247-B100 with 230 VAC, 11 A, 200 Hz, and 3-phase operation. These values are useful when comparing the motor against an existing drive or machine platform. Before installation, buyers should still verify the full electrical and control-side compatibility with the original amplifier and feedback setup.

Q5: What types of applications is the FANUC A06B-0247-B100 suitable for?
A5: This servo motor is suitable for CNC machinery, industrial automation equipment, axis control systems, and compatible FANUC replacement projects. Its combination of 4.0 kW output, αiF22/3000 performance, straight-shaft design, and A1000 feedback makes it especially useful in systems where accurate motion, reliable servo correction, and dependable daily operation are essential.
