FANUC A06B-2089-B103 is a βiS 40/2000-B AC servo motor for feed-axis control in compatible FANUC CNC machines. This exact B103 version has a straight shaft without a keyway, no holding brake and a βiA1000 absolute pulse coder.

It provides 3.0kW rated output, 36Nm continuous low-speed torque and 2000rpm maximum speed. Use the complete nameplate model for replacement; A06B2089B103 is only an auxiliary search reference.

βiS 40/2000-B Axis Performance

Its totally enclosed brushless design and high-resolution feedback support smooth rotation, repeatable positioning and strong acceleration. Actual performance depends on the matched amplifier, parameters and machine load.

B103 Nameplate Configuration

B103 identifies the straight-shaft, no-brake version with βiA1000 pulse coder. Other B-series endings may specify different shaft or brake arrangements. A model carrying #0100 is the separate IP67 version.

Compatibility, Testing and Installation

Confirm A06B-2089-B103, shaft, flange, connectors, pulse coder, amplifier and CNC parameters. REACO CNC checks the housing, shaft, bearings, windings, insulation, feedback and operation as applicable.

Qualified personnel should isolate power, support this 28kg motor securely, protect the encoder and verify coupling alignment. Back up CNC and servo parameters before replacement.
