The FANUC A06B-0142-B176#7075 is an Alpha series AC servo motor designed for CNC feed axes requiring precise positioning and secure holding at standstill. Equipped with an integrated holding brake and an A64 serial encoder, it is commonly used as a replacement motor on machining centers, CNC lathes, and industrial automation equipment fitted with FANUC Alpha systems.

This A06B-0142-B176#7075 corresponds to an Alpha 12 motor rated at 2000 rpm and is typically installed on X, Y, or Z axes depending on the machine configuration. The integrated brake provides mechanical holding when power is removed, making it particularly suitable for vertical axes or applications where unintended movement must be prevented during emergency stops or maintenance operations.

The A64 serial encoder delivers digital position feedback compatible with FANUC Alpha servo amplifiers and many i-Series CNC controls. Combined with the #7075 option code, it defines the exact motor configuration. When replacing an existing unit, matching the complete A06B-0142-B176#7075 reference helps ensure compatibility with the original cabling, connectors, and machine parameters, allowing for a straightforward installation without modification.

Manufactured in Japan, this servo motor is designed for continuous operation in demanding industrial environments. It is frequently used to replace motors affected by encoder failures, worn bearings, weakened brakes, or damaged windings that lead to axis alarms, positioning errors, or unstable axis performance.

Tested or refurbished motors may be available depending on stock. Each motor can be inspected to verify overall operation, encoder communication, and brake functionality before shipment. Standard warranty coverage, worldwide shipping options, and repair or exchange services may also be offered.

For older FANUC Alpha installations, the A06B-0142-B176#7075 provides a practical replacement solution that helps minimize unexpected downtime and keep existing CNC equipment in productive operation.

Frequently asked questions about A06B-0142-B176/7075:

What does the A64 encoder indicate on this Alpha motor
It denotes a FANUC serial pulse coder used on Alpha systems. Match A64 to the existing axis feedback type to keep CNC parameters and amplifier feedback settings consistent.

Can this replace other A06B-0142-B1xx variants like B175
Suffix and option codes affect brake and encoder details, so verify the complete code on the nameplate including the #7075 option. Use the same configuration for a straightforward drop-in replacement.

Where is this motor typically used on a machine
It is commonly installed on feed axes that fit the Alpha 12 frame class, often on vertical or safety-critical axes where the integrated brake prevents motion at rest. Usage depends on the machine builder’s sizing and load requirements.

Is the brake interface compatible with standard FANUC Alpha cabling
Yes, it is intended to work with the Alpha servo amplifier harness and corresponding CNC I/O. Always confirm connectors and cable lengths against the removed unit for a clean swap.

Do you offer refurbished units or exchange service for this model
Depending on availability, refurbished units and exchange programs can be arranged to speed up repair turnaround. These options help maintain uptime while the faulty motor is evaluated or repaired.
