A06B-0123-B175 Fanuc Motor Brake model Alpha 3/3000

Buy online your A06B-0123-B175 Fanuc AC Servo Motor Brake model Alpha 3/3000 reference A06B-0123-B175 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This FANUC AC servo motor from the Alpha 3/3000 family is a field-proven axis motor used across CNC machine tools that require reliable positioning with a holding function. It is designed for integration with FANUC Alpha control platforms and is commonly sourced as a replacement motor on machining centers and lathes where a compact 3000 rpm class unit with a brake and tapered keyed shaft is specified.

The unit combines a tapered shaft with key for secure mechanical coupling and an integrated 8 Nm holding brake that keeps the axis locked at rest, useful for vertical axes and any motion stage that must remain in position at power down. Feedback is provided by a FANUC absolute encoder A64, enabling absolute position support on compatible FANUC controls when the machine is equipped accordingly.

Within the CNC drive chain this motor works with the appropriate FANUC Alpha series servo amplifier sized for the Alpha 3 class, driving linear or rotary axes with stable speed and position control up to 3000 rpm. The tapered keyed output simplifies alignment during motor swaps where the matching hub or coupling is already installed on the machine.

This model is widely used on X, Y, Z feed axes of machining centers, lathe slides, loaders and auxiliary positioning axes that require a compact frame with an integrated brake. For a drop-in field replacement, technicians typically match the full A06B-0123-B175 code to maintain mechanical fit, encoder type and connector orientation.

In maintenance contexts this unit is commonly used as a replacement unit to recover a down axis after encoder faults, brake wear or winding failures. Keeping one in spare inventory helps reduce machine downtime on lines that depend on Alpha 3 axis performance. When planning a field replacement, confirm the mechanical interface, brake requirement and encoder type to ensure a true drop-in replacement.

Technicians choose this model when a compact Alpha motor with an absolute encoder and holding brake is required to restore machine uptime without mechanical rework. It fits well into preventive strategies where a like-for-like CNC replacement component is staged to support critical assets running older FANUC installations.

Each unit is a tested motor, verified on CNC simulators and dedicated servo benches by skilled engineers. Encoder signals, brake function and thermal behavior are checked before packing. Supplied with a warranty and prepared for industrial shipping. Many stocked items ship directly from our Florida facility, and most products are shipped from our Florida warehouse unless otherwise specified on the product page.

For emergency needs this motor can serve as an urgent spare part to cut unexpected downtime. Cnc-shopping USA supports sourcing for obsolete parts and can offer repair or exchange service options when available, helping keep legacy FANUC-based machines in operation.

Frequently asked questions about A06B-0123-B175 :

What feedback device is fitted on this motor
It comes with a FANUC A64 absolute encoder. This supports absolute position capability on compatible FANUC controls, provided the machine’s battery and parameters are maintained correctly.

Does this model include a holding brake and what is the torque
Yes, it includes an integrated brake rated at 8 Nm, suitable for axes that must remain stationary at power off, such as vertical slides.

What is the output shaft configuration
The motor is supplied with a tapered shaft with key, intended to mate with the corresponding tapered hub or coupling installed on the machine.

Is it a direct drop-in for any Alpha 3/3000 motor
Use it as a drop-in when the complete codeA06B-0123-B175 or A06B-0123-B175#7000 matches your original unit. This ensures the same encoder type, brake configuration and mechanical interface.

Which drive system does it work with
It is designed for FANUC Alpha series servo systems where an Alpha 3 class motor is specified. Always verify the drive rating and cabling against the original build.

What is the typical dispatch time and shipping origin
Typical dispatch is noted as within 3 days. Depending on availability, many items ship from our Florida warehouse.
