A06B-0128-B075 Fanuc Servo Motor Alpha 6/3000

Buy online your A06B-0128-B075 Fanuc Motor Alpha 6/3000 reference A06B-0128-B075 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This FANUC Alpha series AC servo motor serves as a feed-axis work unit on FANUC-controlled machine tools, delivering repeatable positioning and smooth contouring at a rated speed of 3000 rpm. Commonly sourced as a replacement motor or tested unit, it supports maintenance teams restoring axis performance on machining centers, CNC lathes and automated fixtures that specify the Model Alpha 6/3000 profile.

Built around FANUC’s Alpha platform, the motor interfaces with FANUC Alpha servo amplifiers for standard axis control. It is equipped with a taper shaft with key to ensure positive mechanical coupling to ballscrews or gearboxes, maintaining drive integrity through frequent start-stop cycles. The integrated A64 absolute encoder, 64K ppr, provides high-resolution feedback within FANUC CNC systems and supports consistent repeatability when parameters and battery backup are properly managed.

The frame, connectors and mounting pattern follow the Alpha family layout, which helps make this unit a practical drop-in replacement on machines originally built with the same rating. Typical roles include X and Y axes on compact vertical machining centers, feed axes on turning equipment, and auxiliary motion where the 6/3000 specification is required. Manufactured in Japan, this reference is widely used by rebuild shops and plant maintenance teams to keep legacy FANUC installations productive.

Reference: A06B-0128-B075

Manufacturer: FANUC

Product type: FANUC AC Servo Motor Model Alpha 6

Main function: Precision feed-axis servo for FANUC-controlled CNC positioning and contouring

Applications: Replacement unit for machining centers, CNC lathes and automated fixtures using Alpha 6/3000 motors; suitable for retrofit and rebuild projects requiring the original Alpha profile

Key technical data: Model Alpha 6/3000 rated for 3000 rpm, taper shaft with key for secure transmission coupling, integrated A64 absolute encoder at 64K ppr, engineered for use with FANUC Alpha servo amplifiers, manufactured in Japan, available as a tested unit with warranty and fast dispatch depending on availability

In day-to-day maintenance, this reference is selected to replace a failed axis motor and recover machine uptime with minimal disruption. Keeping a spare part on the shelf for the 6/3000 rating supports quicker field replacement and shortens repair turnaround when unexpected stops occur. It is equally relevant for retrofit work where the machine builder’s original specification must be preserved.

Each unit is verified by skilled engineers on CNC simulators with servo motors, including encoder communication checks and functional run testing. Motors are packed in protective industrial packaging to safeguard the shaft and feedback hardware. A warranty is provided, and many stocked items ship directly from our Florida facility depending on availability.

For older or obsolete parts that trigger downtime, this reference can act as an emergency CNC replacement component to bring the axis back online. Cnc-shopping USA can also support repair service or exchange service when suitable, helping extend the working life of legacy FANUC equipment while maintaining spare inventory flexibility.

Frequently asked questions about A06B-0128-B075 :

Which feedback device is integrated?
It is fitted with a FANUC A64 absolute encoder rated at 64K ppr. This provides high-resolution position data for FANUC CNCs and helps maintain axis reference when backup and parameters are correctly managed.

What shaft interface does this motor use?
This Fanuc 6/3000 variant uses a taper shaft with key, providing a secure connection to ballscrews or gearboxes under frequent acceleration and deceleration.

Is it compatible with FANUC Alpha servo amplifiers?
Yes, it is designed for use with FANUC Alpha servo amplifiers. Verify mounting, connector orientation and the original machine specification before installation.

Will the machine need homing after replacement?
On systems running absolute mode, homing may be minimized if the encoder battery and CNC parameters are maintained. If not, perform the standard OEM homing routine after installation.

Can repair or exchange be arranged for this reference?
Depending on condition and availability, repair service or exchange service can be organized to reduce downtime and support spare inventory planning.
