The FANUC A06B-0373-B169 is an AC servo motor designed for CNC machinery and industrial motion-control applications where stable axis movement, accurate positioning, and dependable response are essential. In the replacement market, this model is commonly associated with the 1-0SP/3000 configuration and is regularly sought for service, refurbishment, and maintenance work where preserving original system compatibility is a priority.
What makes this motor particularly relevant in industrial aftersales channels is its combination of 3000 RPM performance, integrated brake, and a market profile centered on precision CNC axis use. It is widely presented as a practical replacement option for existing FANUC-controlled equipment, especially when buyers need a motor that aligns closely with the installed mechanical and motion setup rather than a generic substitute.

These are the most stable overlapping details for this model across industrial listings, particularly the 1-0SP/3000 designation, 129 V, 2.9 A, 3-phase, 8-pole, 2 Nm stall torque, and brake-equipped configuration. Most listings describe the motor with a tapered shaft, while some marketplace listings use more item-specific wording, so exact installed-unit matching remains important when fitment is critical.
In real machining and automation environments, a servo motor has to do more than reach a rated speed. It needs to deliver controlled acceleration, stable deceleration, repeatable positioning, and predictable axis behavior over long operating cycles. The A06B-0373-B169 fits that role well in CNC systems where maintaining original motion characteristics matters during repair or replacement work. Its commonly listed 3000 RPM speed and 2 Nm stall torque make it suitable for controlled axis movement in precision machine applications.
The integrated brake adds practical value in applications where stopping control and position holding are important, while the motor’s market-recognized configuration helps buyers identify it as a matching replacement for compatible FANUC setups. For maintenance teams, machine rebuilders, and spare-parts buyers, that combination makes this motor a sensible option when the goal is to restore machine performance without unnecessary system changes. This final point is an inference based on how the model is described and sold across industrial replacement channels.
One reason the A06B-0373-B169 continues to attract demand is that buyers searching for this exact part number are usually working from an existing machine requirement, not browsing for a general-purpose motor. In those situations, consistency matters: the right servo motor helps preserve known machine behavior, reduces integration uncertainty, and supports faster repair planning. That practical replacement value is exactly why part-specific FANUC motors remain important in CNC maintenance and industrial support environments. The final two points are inferences based on replacement-market patterns for this model.
Q1: What type of product is the FANUC A06B-0373-B169?
A: It is an AC servo motor used in CNC machinery and industrial motion-control systems. Market listings consistently place it in the FANUC servo motor category and associate it with the 1-0SP/3000 configuration for precision axis applications. That makes it especially relevant for repair, replacement, and machine-support work where controlled motion performance matters.
Q2: Does the A06B-0373-B169 include a brake?
A: Yes. Public listings consistently describe this model as a brake-equipped servo motor. In practical use, that is valuable for applications where controlled stopping and load holding are important, including machine axes that must maintain position during pauses, shutdown, or specific motion sequences.
Q3: What are the key technical characteristics buyers usually look at for this motor?
A: The most commonly repeated characteristics are 1-0SP/3000 configuration, 3000 RPM, 129 V, 2.9 A, 3-phase, 8 poles, and 2 Nm stall torque. These details are useful because they help buyers compare the motor against the installed unit and confirm whether it aligns with the original machine setup before purchase.
Q4: What shaft style is associated with this model?
A: Most industrial listings describe the A06B-0373-B169 as a tapered-shaft version. Shaft style is an important detail in servo replacement work because it affects mechanical fit, coupling compatibility, and how closely the new unit matches the motor already installed on the machine. Since some marketplace listings can use item-level wording, checking the installed motor before ordering is still the safest approach when fitment is critical.
Q5: Is the A06B-0373-B169 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 generally look for this exact model when they want to restore machine performance with a closely matched servo motor instead of redesigning the system around a different motion platform. The second sentence is an inference based on how the part is positioned across industrial replacement listings.
