A06B-0142-B077#7012 Fanuc Motor Model Alpha 12/2000 V-Groove keyed shaft

Buy online your Fanuc Motor Model Alpha 12/2000 V-Groove keyed shaft reference A06B-0142-B077-7012 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This FANUC A06B-0142-B077-7012 is a FANUC Alpha 12/2000 AC servo motor designed for precision feed-axis and positioning applications on FANUC-controlled CNC machines. With a rated power of 2.1 kW, a maximum speed of 2,000 rpm and a stall torque of 12 Nm, it is suitable for medium-duty axes on machining centers, CNC lathes, routers, grinders and other industrial equipment.

The motor is designed to operate with compatible FANUC α-series servo amplifiers and features an integrated I64 incremental pulse coder for accurate closed-loop position feedback. Its V-groove keyed shaft provides secure mechanical coupling for pulleys and belt-driven systems, while the integrated holding brake helps maintain axis position when the machine is stopped or powered down.

The motor is rated at 7.4 A, 186 V AC three-phase and 133 Hz. The Alpha 12/2000 configuration provides a 2,000 rpm operating class suitable for feed axes requiring stable torque, accurate positioning and repeatable motion. The B077#7012 option code identifies the specific mechanical and feedback configuration and should be matched with the original motor before replacement.

Manufactured in Japan, this FANUC servo motor is suitable as a CNC replacement motor, industrial spare part, replacement unit or emergency spare. It is commonly used for X, Y and Z axes, axis rebuilds, preventive maintenance and retrofit projects where maintaining the original mechanical mounting, shaft configuration and feedback system helps simplify installation and commissioning.

Each motor supplied by Cnc-shopping can be inspected and functionally tested on appropriate CNC test equipment with a compatible FANUC servo amplifier when applicable. Products are securely packaged for industrial transportation and supplied with a commercial warranty, with fast dispatch, worldwide shipping, obsolete-part sourcing, repair and exchange services available depending on stock and condition.

In the field, this motor is used to recover axis precision after encoder faults, bearing wear or winding issues on the original unit. Maintenance teams often keep one in industrial spare inventory as a replacement unit to limit machine downtime, especially on high-use axes. For planned overhauls or retrofits, matching the option code ensures shaft style and feedback configuration align with the existing pulley set and amplifier parameters, which shortens restart time.

Units supplied by Cnc-shopping can be a tested unit or a refurbished unit depending on sourcing and availability, suitable as a CNC replacement component to extend machine lifetime and stabilize uptime. This model is commonly sourced as a spare part for shops that run legacy FANUC controls and want consistent mechanical interchangeability without rewiring or bracket changes.

Each motor is functionally evaluated by skilled engineers on CNC simulators with servo motors, with attention to feedback signals, smooth running and thermal behavior under load. Packaging is prepared for industrial transport with protective cushioning and secure shaft protection. Warranty and lead time are provided according to our service terms, with fast dispatch depending on availability.

When an obsolete part threatens production, this model can serve as an emergency spare to cut unexpected downtime. Cnc-shopping supports sourcing for legacy FANUC equipment, and repair service or exchange service may be available for selected variants. With the right spare strategy, older CNC installations can remain operational for years.

Frequently asked questions about A06B-0142-B077-7012:

Which FANUC systems typically use this Alpha 12/2000 motor?
It is commonly paired with FANUC α-series servo amplifiers on machines running FANUC 0i and i‑Series controls. Always confirm the motor nameplate and option code against the drive label before ordering.

What is the shaft configuration on this variant?
This version features a V-groove keyed shaft that suits belt and pulley coupling. Verify pulley width and key dimensions with your existing hardware to keep alignment consistent.

Is this a drop-in replacement for A06B-0142-B077 without the #7012 code?
The base family is the same, however the #7012 option defines mechanical and feedback details. Match both the B-code and # code to your original unit to ensure full interchangeability.

Does the motor include the feedback device?
Alpha motors are supplied with a FANUC pulse coder interface integrated in the assembly. Check the original nameplate to confirm the required feedback variant so parameters and homing behavior remain unchanged.

Can you support refurbished or exchange options?
Depending on sourcing, a refurbished unit or an exchange service may be offered for faster turnaround. Contact us with your nameplate details for current availability and lead time.
