FANUC A06B-0061-B403 AC Servo Motor with Brake for CNC Precision Motion Systems

Product Overview

The FANUC A06B-0061-B403 is an AC servo motor designed for CNC machinery and industrial motion-control applications where stable speed performance, precise positioning, and dependable axis response are essential. In replacement and maintenance work, this model is commonly selected for situations where preserving original machine compatibility matters just as much as restoring motion accuracy. It is widely identified as a BiS2/4000 servo motor with a straight smooth shaft, 24V brake, and b128ia feedback configuration.

Technical Data

Built for Accurate and Stable Servo Performance

In real production environments, servo motors are expected to do much more than simply rotate. They need to provide smooth acceleration, controlled deceleration, repeatable axis travel, and reliable response under continuous operating conditions. The A06B-0061-B403 fits that role well, especially in CNC systems where maintaining original motion characteristics is a priority during repair or replacement work. With its 0.5 kW output, 4000 RPM speed, and 2 Nm stall torque, this motor is well suited for applications that demand fast and controlled servo response.

The integrated 24V brake adds practical value in applications that require holding performance or controlled stopping, while the straight smooth shaft design supports mechanical compatibility in matching assemblies. For maintenance teams and parts buyers, this makes the motor a practical option when the goal is to restore an installed FANUC system with a compatible replacement instead of adapting a different motor platform. The final point is an inference based on how this part is described and sold across replacement channels.

FAQ

Q1: What type of product is the FANUC A06B-0061-B403?
A: It is an AC servo motor used in CNC machinery and industrial motion-control systems. It is commonly listed as a BiS2/4000 model and is typically associated with applications that require accurate positioning, stable axis response, and reliable servo performance.

Q2: What are the main technical characteristics of the A06B-0061-B403?
A: The most consistently listed specifications include 0.5 kW rated output, 156 V continuous voltage, 4000 RPM rated speed, 1.9 A AC current, 267 Hz operating frequency, 200–230 V AC input at 50/60 Hz, 2 Nm stall torque, and 3.3 A stall current. It is also commonly described as a straight smooth shaft motor with a 24V brake and b128ia feedback reference.

Q3: Does the A06B-0061-B403 include a brake?
A: Yes. This model is commonly described as a 24V brake-equipped servo motor. That makes it especially suitable for machine applications where controlled stopping or holding performance is important, including equipment that must maintain axis position during pauses or shutdown.

Q4: What shaft style is associated with this motor?
A: Public listings commonly describe this motor as having a straight smooth shaft. In practical replacement work, shaft style is a critical detail because it affects coupling compatibility, installation fit, and how closely the motor can match the original machine assembly.

Q5: Is this motor suitable for replacement and maintenance projects?
A: Yes. This motor is well suited for CNC repair, industrial maintenance, refurbishment, and spare-parts stocking where maintaining original FANUC compatibility is important. Buyers usually search for this exact model when they want to restore machine performance with a matching servo motor rather than redesign the motion setup around another platform. The final sentence is an inference based on how the model is presented in industrial replacement listings.
