FANUC A06B-0373-B175 AC Servo Motor with Brake for CNC and Industrial Motion Control

Product Overview

The FANUC A06B-0373-B175 is an AC servo motor built for CNC machinery and industrial motion-control systems that require accurate positioning, stable speed performance, and dependable axis response. In industrial replacement and maintenance settings, this model is widely recognized as a practical solution for restoring original machine performance while maintaining compatibility with existing FANUC configurations. It is commonly identified as an A2/3000 servo motor with a tapered shaft, brake, and A64 feedback.

For buyers working with installed CNC systems, the value of this motor usually comes from fit, continuity, and predictable motion behavior rather than broad interchangeability. Because this version is consistently listed as a brake-equipped tapered-shaft motor, it is especially relevant for service projects where original mechanical matching and controlled stopping performance matter.

Technical Data

The most consistently repeated market-listed details for this model are A2/3000, 3000 RPM, 2.6 A, 200–230 V AC, 50/60 Hz, 3-phase, tapered shaft, brake, and A64 feedback. One listing also gives a weight reference of approximately 6.8 kg, which can be useful for logistics and replacement planning.

Built for Reliable CNC Servo Performance

In real manufacturing environments, servo motors are expected to deliver more than rotational output. They need to provide smooth acceleration, stable deceleration, accurate positioning, and repeatable motion over long operating cycles. The A06B-0373-B175 fits that role well in CNC and automation systems where preserving original machine behavior is important during repair or replacement work. Its commonly listed configuration makes it a strong option for buyers looking for a matched FANUC servo motor rather than a generic substitute.

The built-in brake adds practical value in applications where holding performance and controlled stopping are important. At the same time, the tapered shaft design supports secure mechanical fitment in compatible assemblies, which is often a critical consideration when replacing a failed motor in an existing machine. This combination makes the motor suitable for CNC repair, rebuild projects, spare-parts sourcing, and ongoing maintenance programs.

Key Features

Application Advantages

For maintenance teams, machine rebuilders, and industrial spare-parts buyers, the A06B-0373-B175 is a sensible choice when exact compatibility matters more than generic replacement flexibility. It is commonly relevant for CNC machine tools, servo axis replacement work, industrial automation systems, and service environments where restoring original performance is the main priority.

Another reason this motor remains in demand is that buyers searching for this exact part number are often trying to reduce downtime and keep an installed FANUC system running without unnecessary design changes. In that context, a brake-equipped servo motor with established replacement-market visibility is often the preferred route for efficient maintenance planning. This is an inference based on how the product is described across industrial replacement listings.

FAQ

Q1: What type of product is the FANUC A06B-0373-B175?
A: It is an AC servo motor used in CNC machinery and industrial motion-control applications. Market listings consistently place it in the FANUC servo motor category and describe it as an A2/3000 model used for precise machine-axis operation.

Q2: Does the A06B-0373-B175 include a brake?
A: Yes. Public listings consistently describe this motor as a brake-equipped version. That makes it especially suitable for applications where holding force and controlled stopping are important, including equipment that needs stable axis position during pauses or shutdown.

Q3: What shaft style does this motor use?
A: This model is commonly listed with a tapered shaft. In replacement work, shaft style is a critical specification because it directly affects coupling compatibility, installation fit, and the ability to match the original machine assembly.

Q4: What feedback type is associated with the A06B-0373-B175?
A: Public product listings commonly associate this motor with A64 feedback. That makes it relevant for systems that depend on consistent position and speed feedback for controlled servo operation within compatible FANUC platforms.

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 sourcing where maintaining original FANUC compatibility is important. Buyers usually select it when they want to restore an installed machine with a matching servo motor rather than switch to a different motor platform. The final sentence is an inference based on the way the motor is presented across replacement-market listings.
