New FANUC A06B-0247-B400 AC Servo Motor with Brake for CNC Motion Control

The FANUC A06B-0247-B400 AC Servo Motor is built for CNC systems and industrial automation equipment that require stable torque output, dependable servo response, and accurate positioning throughout long operating cycles. In practical use, a motor in this class must do more than deliver power. It must react smoothly to control commands, remain composed under changing loads, and support the kind of repeatable motion quality that modern machining and automated production depend on. This model is well suited to that role, making it a strong option for machine tools, industrial motion assemblies, and professional replacement projects.

Key Technical Data

The specification profile of this motor makes it particularly suitable for applications where controlled torque, reliable stopping performance, and stable servo feedback are all important. With 4 kW output and 3000 RPM operating speed, it supports solid axis performance in equipment that needs both motion strength and positioning consistency. The inclusion of a 24V DC brake adds value in systems where holding performance after stop is essential, while the A1000 feedback configuration helps maintain accurate motion correction during daily operation.

A Practical Servo Motor for Demanding Industrial Use

What makes this motor valuable is not only its output level, but the way its overall configuration supports real production requirements. In CNC and automation environments, motion quality often matters just as much as raw power. The motor must accelerate smoothly, hold steady when the load changes, and work with the control system to keep positioning repeatable from cycle to cycle.

The A06B-0247-B400 fits that kind of application well. Its 22 Nm torque gives it enough force for demanding servo tasks, while the 3000 RPM speed class supports efficient axis movement without compromising control stability. This makes it suitable for installations where machine uptime, motion accuracy, and predictable daily operation all carry equal importance.

Brake-Equipped Design for Better Holding Performance

A built-in brake can be one of the most important features in a servo motor replacement, especially in systems where the axis must hold position after the drive stops. This model is commonly described with a 24V brake, making it particularly relevant for machines that require controlled stopping and reliable holding behavior.

In real industrial settings, that can help reduce unwanted movement when power is removed or when the machine is not actively driving the axis. For maintenance teams and rebuilders, a brake-equipped motor is often more than a convenience feature. It is part of preserving the original operating behavior of the machine and supporting safer, more controlled shutdown conditions.

Straight Shaft and A1000 Feedback for Easier Compatibility

Successful servo replacement depends on more than matching the part number. Mechanical fit and feedback configuration both have a major effect on how well the motor performs after installation. This model is widely listed with a straight shaft and A1000 / AiA1000 pulse coder, a combination that gives buyers a clearer compatibility profile when comparing it against existing equipment.

That matters because the right shaft style can simplify coupling and alignment, while the correct feedback device helps the control system maintain accurate speed and position monitoring. For users working with established FANUC-based machinery, these details can make the difference between a straightforward installation and a time-consuming retrofit process.

Suitable Applications

The FANUC A06B-0247-B400 AC Servo Motor is commonly considered for:

• CNC machine tools

• Industrial automation equipment

• Precision axis control systems

• Servo replacement in compatible FANUC installations

• Motion control applications requiring brake-equipped servo performance

FAQ

Q1: What is the rated output of the FANUC A06B-0247-B400?
A1: The FANUC A06B-0247-B400 is commonly listed with a rated output of 4 kW. This places it in a performance range suitable for CNC and industrial automation systems that require stronger servo capability than smaller motor classes can provide. In practical applications, this output level supports solid axis drive performance while still allowing the control system to maintain precise and stable motion behavior.

Q2: Does the A06B-0247-B400 include a brake?
A2: Yes. Available product listings consistently describe this motor with a 24V DC brake. That brake is especially useful in applications where the axis must hold position after stop or where controlled shutdown behavior is important. In many CNC and industrial systems, a brake-equipped servo motor helps reduce unintended movement and supports better positional stability when the machine is not actively driving the load.

Q3: What shaft and feedback configuration is commonly associated with this model?
A3: This motor is commonly described with a straight shaft and an A1000 or AiA1000 pulse coder. These two details are important because they affect both mechanical fit and control-side compatibility. For service work and replacement projects, confirming shaft style and feedback type early can help reduce installation issues and improve the chance of restoring the machine’s original motion characteristics.

Q4: What performance characteristics are commonly listed for the A06B-0247-B400?
A4: Public distributor data commonly associates this model with 4 kW output, 3000 RPM speed, 22 Nm torque, 11 A current, 200 Hz frequency, and 3-phase AC voltage type. Together, these figures indicate a servo motor intended for industrial motion systems where controlled torque, stable operation, and dependable response are required. For buyers evaluating replacement options, these are some of the most useful baseline specifications to compare against the installed motor.

Q5: What types of applications is the FANUC A06B-0247-B400 suitable for?
A5: This servo motor is suitable for CNC machinery, industrial automation equipment, axis control systems, and compatible FANUC replacement applications. Its combination of 4 kW output, straight shaft, 24V brake, and A1000 feedback makes it especially relevant in systems where accurate motion, stable holding performance, and reliable long-term operation are essential to machine performance.
