Fanuc AC Servo Motor A06B-0377-B077

Product Overview

The Fanuc A06B-0377-B077 is an AC servo motor designed for CNC machinery and industrial automation systems that depend on stable motion control, accurate positioning, and dependable operating consistency. It is commonly identified in the market as an AM2.5/3000 servo motor and is used in applications where maintaining original machine compatibility is a priority.

For replacement and maintenance work, this motor is often selected by buyers who need a like-for-like FANUC solution rather than a general-purpose substitute. Public product listings consistently describe this model as a tapered shaft version associated with i64 feedback, making it well suited for CNC repair, retrofit, and machine rebuild projects.

Technical Data

The most consistently supported public details for this model are the AM2.5/3000 configuration, 0.4 kW output, 2.5 Nm torque, 3-phase design, maximum 3000 RPM, no brake, and a tapered keyed shaft layout. One supplier also describes the motor as fitted with standard IP65 FANUC seals.

Built for Precision Motion Applications

In real industrial use, servo motors need to deliver repeatable axis control, smooth acceleration, and predictable response under continuous operating conditions. The A06B-0377-B077 fits that requirement well, especially in machine tools and automation systems where preserving original motion performance is important. Its published configuration makes it a practical choice for users servicing existing FANUC-controlled equipment.

Because this model is generally offered as a direct replacement-style FANUC servo motor, it is particularly suitable for buyers focused on mechanical fit, motion consistency, and straightforward integration into compatible CNC platforms. That makes it relevant for repair departments, plant maintenance teams, and industrial spare-parts sourcing.
