A06B-0443-B200 Fanuc Linear Motor model LiS900A1/4

Buy online your A06B-0443-B200 Fanuc Linear Motor model LiS900A1/4 from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The FANUC A06B-0443-B200 linear motor from the Alpha i series is designed for the direct control of linear axes on high-precision CNC machine tools. Used without mechanical transmission or ball screws, it enables fast, precise movements with no mechanical backlash, making it particularly well-suited for applications requiring high positioning accuracy.

This LiS900A1/4 model is integrated into FANUC Alpha i servo systems and operates with amplifiers configured for linear control. It is used on machining centers, grinding machines, EDM equipment, and transfer axes requiring excellent repeatability and smooth high-speed interpolation.

The motor operates at 132 V with a rated current of 15.8 A, a frequency of 133 Hz, and an IP54 protection rating. Its direct-drive architecture reduces mechanical wear and improves axis stability on machines used in high-volume production.

The A06B-0443-B200 motor is commonly used as a replacement part to quickly restore an axis following a motor failure, winding defect, or thermal alarm. To ensure compatibility, it is recommended to verify the full part number, LiS series, cable lengths, and servo parameters corresponding to the original machine.

Each motor can be tested before dispatch on CNC simulators to verify electrical behavior, servo response and operational integrity. Industrial protective packaging and support for repair, exchange or sourcing of older FANUC components may be available depending on stock and service conditions.

Frequently asked questions about A06B-0443-B200:

Which FANUC drives are typically used with this linear motor?
It is applied with FANUC Alpha i servo amplifiers that support linear motor control. Confirm the exact amplifier type and axis rating against the machine builder’s specification and the motor’s part code.

Is this a drop-in replacement for any LiS900 variant?
Match the full code A06B-0443-B200 and the LiS900A1/4 designation to ensure a like-for-like swap. Differences in winding, connectors or mounting can exist between close variants, so verify against the original nameplate.

Does the supply include magnetic tracks or cables?
This reference commonly corresponds to the motor assembly only. Tracks, cables and ancillary hardware are application-specific and should be sourced based on the machine’s OEM bill of materials.

Can a refurbished unit be provided if new stock is limited?
Depending on availability, a refurbished unit or tested unit can be offered to support urgent maintenance. Contact our team for current options and lead times.

What should maintenance teams prepare for replacement?
Have the original parameters and axis data backed up, confirm mechanical fit and cable routing, and plan a verification run after installation. Follow the machine builder’s procedures for alignment and servo tuning.
