A06B-0128-B075 Fanuc Motor Alpha 6/3000

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

This FANUC Alpha series AC servo motor operates as a feed-axis workhorse on FANUC-equipped machine tools. It delivers accurate motion control for positioning and contouring tasks and is frequently sourced as a replacement unit or tested spare part to restore CNC axis performance on the production floor.

Built as a Model Alpha 6/3000, the unit is designed for a rated speed of 3000 rpm, giving stable axis motion for compact machining centers, turning equipment and automated fixtures that rely on precise incremental moves. The taper shaft with key provides a positive mechanical interface to the ballscrew or gearbox, which helps maintain coupling integrity under repeated acceleration and deceleration.

Feedback is provided by a FANUC A64 absolute encoder with 64K ppr, enabling high-resolution position data within FANUC CNC systems. Absolute feedback is widely used to minimize re-referencing after service interventions and supports consistent axis repeatability when parameters and battery conditions are properly maintained.

The motor is engineered to run with FANUC Alpha servo amplifiers in standard axis control applications. Its dimensions and connection scheme follow the Alpha family design, making it a practical drop-in replacement on machines originally equipped with the same frame rating. Typical use includes X, Y or auxiliary axes where the 6/3000 profile is specified by the machine builder.

In maintenance contexts this motor is often selected to replace a failed axis unit and quickly recover machine uptime. Keeping a stocked spare or arranging a field replacement plan for this reference helps reduce downtime risk on legacy equipment that still runs daily production. It also fits retrofit and rebuild scenarios where the original Alpha 6/3000 specification must be preserved.

Each motor is verified by skilled engineers on CNC simulators with servo motors, including encoder communication checks and functional run testing. Units are packed in protective industrial packaging to safeguard the shaft and feedback hardware. A warranty is provided, and shipping options are available for domestic and worldwide needs.

When an obsolete part causes an unexpected stop, this reference can serve as an emergency CNC replacement component to get the axis back online. Cnc-shopping can also support repair service or exchange service options when appropriate, helping extend the operating life of older FANUC installations.

Frequently asked questions about A06B-0128-B075 :

Which encoder is fitted on this motor?
It comes with a FANUC A64 absolute encoder rated at 64K pulses per revolution, suitable for high-resolution axis positioning within FANUC CNC systems.

What shaft configuration does this model use?
This Alpha 6/3000 variant is supplied with a taper shaft with key, providing a secure connection to the machine’s mechanical transmission.

Is it a drop-in replacement for machines using Alpha 6/3000?
In most cases yes, provided the machine was originally specified for the same Alpha 6/3000 frame and uses compatible FANUC Alpha servo amplifiers. Verify shaft interface, mounting, and connector orientation before installation.

Do I need to perform a home routine after installation?
Systems using absolute mode may retain position data if encoder backup and CNC parameters are maintained. If not, your maintenance team may perform the standard machine homing procedure required by the OEM.

Can you support repair or exchange for this Fanuc servo motor reference?
Yes, depending on condition and availability, repair service or exchange service can be arranged to help manage spare inventory and reduce downtime.
