New FANUC A06B-0272-B100 AC Servo Motor for CNC Precision Motion Control

The FANUC A06B-0272-B100 AC Servo Motor is built for CNC equipment and industrial automation systems that need strong torque delivery, consistent servo response, and dependable positioning accuracy during continuous operation. Designed for demanding motion-control environments, this motor is a practical fit for machine tools, automated production lines, and replacement projects where stable axis behavior and long-term reliability matter.

Key Technical Data

The specification profile associated with this model makes it especially suitable for applications where both motion strength and control accuracy are important. With 5.5 kW rated output, 40 Nm stall torque, and 4000 min⁻¹ maximum speed, it can support fast-response positioning while maintaining the controlled servo behavior expected in precision industrial equipment. The commonly listed straight shaft with key and a1000 pulse coder also make it relevant for buyers focused on system compatibility in FANUC-based installations.

Built for Responsive and Stable Servo Operation

In real production settings, a servo motor has to do more than generate motion. It needs to react smoothly to command changes, remain stable through changing loads, and support repeatable motion quality over long duty cycles. The A06B-0272-B100 fits that requirement well because its output and torque characteristics place it in a performance range suitable for serious CNC and automation work.

Its 40 Nm stall torque gives the motor the strength needed for controlled acceleration and dependable low-speed servo behavior, while the 130 Nm maximum torque provides reserve capacity for short-duration demand peaks. In practice, this helps improve axis responsiveness without sacrificing motion stability, which is especially valuable in equipment where inconsistent servo behavior can affect machining accuracy or production efficiency.

Straight Shaft Design for Practical Machine Integration

Mechanical compatibility plays a major role in any servo motor replacement. This model is commonly listed with a straight shaft with key, a configuration that supports secure coupling and practical integration in compatible systems. When a replacement motor must match the original machine layout closely, shaft design can be just as important as speed class or electrical performance.

For maintenance teams and industrial buyers, that matters because the correct mechanical fit can reduce installation issues and help preserve original motion characteristics. In everyday service work, a motor that matches both the control requirements and the shaft arrangement gives a much better chance of restoring stable machine behavior with less adjustment.

Reliable Feedback for Precision Control

This motor is commonly associated with an a1000 pulse coder, which supports the feedback quality needed for accurate speed and position monitoring. In CNC and industrial automation systems, dependable feedback helps the control system perform smoother correction, maintain better repeatability, and improve overall motion consistency. That is one of the reasons this motor remains a practical choice for installations where positioning accuracy is directly tied to machine performance.

Suitable Applications

The FANUC A06B-0272-B100 AC Servo Motor is commonly considered for:

• CNC machine tools

• Industrial automation systems

• Precision axis control assemblies

• High-demand motion-control equipment

• Compatible FANUC servo motor replacement projects
