New FANUC A06B-0372-B575 AC Servo Motor | 2000 RPM Servo Motor for CNC Replacement and Motion Control

The FANUC A06B-0372-B575 is the kind of servo motor people usually search for when a machine is already down and the priority is getting it back to its original running condition without wasting time on uncertain substitutes. Public listings for this exact part consistently place it in the A2/2000 class and describe it as a 3-phase 120 VAC, 2.2 A, 133 Hz, 2000 RPM AC servo motor with a straight shaft, A64 pulse coder, and no brake configuration, making it a strong fit for FANUC-based CNC equipment and other industrial motion systems that need a close-match replacement rather than a generic alternative.

Technical Data

The table above reflects the specification set that is supported most consistently for this exact model: the manual gives the stable α2/2000 performance values such as 0.4 kW, 2.0 N·m, 2.2 A, 0.00060 kg·m² rotor inertia, and 16 N·m maximum theoretical torque, while exact-part listings confirm straight shaft, A64 feedback, 120 VAC, 133 Hz, and 2000 RPM for A06B-0372-B575.

What makes this version commercially useful is not some abstract spec-sheet appeal. It sits in a very practical part of the FANUC range. A servo in the 0.4 kW / 2000 RPM range is often exactly what maintenance teams need for feed axes, compact positioning systems, and small-to-medium CNC applications where restoring the original feel of the machine matters more than trying to force in a larger motor that creates mounting, tuning, or feedback-side complications. The straight-shaft layout is especially relevant in replacement work, because shaft style affects coupling and fit just as much as voltage and speed do.

The A64 pulse coder is just as important as the mechanical side. In FANUC systems, feedback configuration is one of the first things that should match when replacing a servo motor. A motor can look close enough on paper and still become a poor choice if the feedback format is wrong. That is why this model tends to be a more sensible option when the installed machine already uses the same part number or the same A2/2000 straight-shaft A64 configuration. It reduces guesswork, lowers the risk of compatibility issues, and usually makes the return-to-service process much more straightforward.

In practical buying terms, the A06B-0372-B575 is best suited to CNC repair, planned spare stock, servo replacement, and legacy system support. It is not the kind of part people buy because they want to redesign a machine from scratch. It is the kind they buy because production time is expensive, the original motor matters, and the safest decision is usually to stay as close as possible to the installed FANUC specification.

FAQ

Q1: What is the FANUC A06B-0372-B575 mainly used for?

A: This motor is mainly used in FANUC-based CNC machines and industrial automation equipment as a feed-axis or motion-control servo. In real purchasing situations, it is most often sourced for replacement work or kept as a spare so a failed machine can be returned to service with a motor that matches the original electrical and feedback setup closely enough to avoid unnecessary integration problems.

Q2: What are the most important specifications to confirm before ordering?

A: The first details most buyers verify are the part number, A2/2000 motor class, 0.4 kW output, 2000 RPM speed, 2.0 N·m torque at stall, 2.2 A current, 3-phase 120 VAC, 133 Hz, straight shaft, and A64 pulse coder. Those are the core identifiers that determine whether the replacement is likely to match the motor already installed on the machine.

Q3: Why does the shaft style matter so much on this model?

A: Shaft style affects more than appearance. It directly influences coupling fit, installation alignment, and whether the replacement motor will drop back into the existing mechanical assembly without additional rework. Exact listings for A06B-0372-B575 identify it as a straight-shaft version, and some listings also specify a keyway, so checking the existing motor’s shaft configuration before purchase is one of the safest ways to avoid fitment issues during installation.

Q4: Is the A64 pulse coder important when replacing this servo motor?

A: Yes. The feedback device is a critical part of servo compatibility. Exact listings for this part identify it with an A64 pulse coder, and that matters because the control system depends on the correct feedback format to read position accurately and behave as expected. Even if another motor seems similar in size or speed, a mismatch in feedback configuration can still create control-side problems, so this is one of the most important details to verify.

Q5: Is this a good model to keep in spare inventory?

A: For facilities already running machines that use this exact motor, yes. Keeping the right servo motor in stock can cut downtime significantly, especially when a failed axis would otherwise hold up production while purchasing and engineering teams try to confirm an equivalent. Because A06B-0372-B575 has a clearly established configuration across multiple listings, it is a practical spare to hold when the machine base already depends on this specification.
