The FANUC A06B-0247-B100 is a 200V-class αiF 22/3000 AC servo motor for CNC feed axes. It provides 4.0kW rated output, 22Nm stall torque and 3000rpm maximum speed. B100 specifies a straight shaft, standard non-brake construction and an αiA 1000 absolute Pulsecoder.

A06B-0247-B100 Product Specifications

B100 Shaft and Encoder Configuration

In FANUC’s ordering code, B100 identifies a straight shaft, standard construction without a fan or high-torque brake, and the αiA 1000 absolute Pulsecoder. This encoder is also written as A1000i in some legacy listings. A missing # suffix means the standard specification rather than the optional #0100 IP67 version.

Understanding the 11A and 18.4A Values

The nameplate may show 11A as an operating rating, while FANUC lists 18.4A RMS as stall current. They describe different conditions and must not be substituted when selecting cables, amplifiers or protection devices.

Compatibility, Testing and Installation

Confirm A06B-0247-B100, the winding, shaft, flange, αiA 1000 feedback, connectors, servo amplifier and machine parameters. Other A06B-0247 variants may have a taper or keyed shaft, brake, incremental encoder or IP67 suffix and are not automatically interchangeable.

REACO CNC checks the nameplate, bearings, shaft, connectors, insulation, windings, encoder feedback, rotation, current and vibration as applicable. Protect the shaft and encoder during lifting and installation.
