FANUC A06B-0102-B078 αE2/3000 AC Servo Motor with αA8B Absolute Pulse Coder

The complete A06B-0102-B078 number should be used when comparing the replacement motor. Motors with a similar frame or the same αE family name may use a different shaft, brake arrangement or feedback detector.

Verified Motor Configuration

• Manufacturer: FANUC
• Part number: A06B-0102-B078
• Motor model: αE2/3000
• Rated output: 0.5 kW
• Maximum speed: 3,000 min⁻¹
• Rated torque at stall: 2.0 N·m
• Shaft: Standard straight shaft without keyway
• Holding brake: No brake identified by the B078 ordering code
• Feedback: αA8B serial absolute pulse coder, 8,192 divisions per revolution
• Signal connection: D-sub 15-pin connector

Speed-torque performance depends on the matching servo amplifier, input voltage, software and parameter settings. The ratings above identify the motor family but do not establish compatibility with every FANUC control or amplifier.

Absolute Feedback and Connection Check

The αA8B pulse coder is an absolute feedback device, not an incremental encoder. Absolute-position retention depends on the appropriate CNC or servo-amplifier backup system. Preserve machine parameters and follow the manufacturer’s encoder and battery procedures when removing or installing the motor.

Confirm the D-sub signal connector, motor power connection and cable orientation against the existing assembly. Cables, connectors and the servo amplifier are not assumed to be included unless they are specifically shown in the REACO CNC quotation.

Replacement and Compatibility Guidance

Before ordering, compare the complete A06B-0102-B078 nameplate with the removed motor. Check the αE2/3000 designation, straight non-keyed shaft, absence of a brake, αA8B feedback, connector layout, mounting dimensions and the applicable FANUC servo amplifier.

Send REACO CNC clear photos of the motor nameplate, shaft and connectors together with the CNC or machine model. We can review visible identifiers before confirming the available unit, condition, price and lead time.

Tested Supply from REACO CNC

REACO CNC checks the offered motor by full model number and function before dispatch. Available condition may be new surplus, used or refurbished and will be confirmed in the quotation.
