A06B-1406-B103 Fanuc Spindle Motor Fanuc Alpha i 6/10000 (5,5 kW / 7.5kW)

Buy online your A06B-1406-B103 Fanuc Spindle Motor Fanuc Alpha i 6/10000 (5,5 kW / 7.5kW) reference A06B-1406-B103 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This FANUC Alpha i series AC spindle motor is a high-speed unit used as the main spindle drive on CNC machine tools. It delivers controlled torque and stable speed for milling, turning and drilling operations when paired with the correct FANUC Alpha i spindle amplifier. Commonly sourced as a replacement motor or spare part, it helps restore uptime on machines using the 6/10000 power and speed class.

The Alpha i 6/10000 designation identifies a 10,000 rpm class spindle motor in the 5.5 to 7.5 kW range, widely used on compact machining centers, turning centers and drill-tap platforms. Within a FANUC CNC system it operates in closed loop with the spindle amplifier, managing acceleration, speed hold and decel under load while maintaining thermal safety through integrated sensors.

Mechanical and electrical options defined by the B103 code align the shaft, connector set and feedback package with specific machine-tool requirements. When replacing an existing A06B-1406-B103 unit of the same option, the motor is typically a drop-in fit with existing cabling, mounting and parameters preserved by the CNC, which reduces commissioning time after swap-out.

This unit is part of the FANUC Alpha/Alpha i spindle family widely deployed across Japanese and European-built machine tools. Its build quality and balance accuracy support stable cutting at high spindle speeds, which matters in real shop conditions where heat, coolant mist and fine chips are present around the headstock or spindle cartridge.

Reference: A06B-1406-B103

Manufacturer: FANUC

Product type: FANUC Servo Motor AC Model Alpha

Main function: High-speed AC spindle drive motor providing torque and speed control for FANUC Alpha i spindle systems.

Applications: CNC machining centers, turning centers and drill-tap machines requiring a 10,000 rpm spindle class in the 5.5 to 7.5 kW range.

Key technical data: Alpha i 6/10000 power class with approx. 5.5 kW to 7.5 kW rating per model designation, FANUC Alpha i spindle ecosystem compatibility when matched to the correct spindle amplifier, manufactured in Japan, typical lead time 5 to 8 days. Supplied as a replacement unit for machines originally equipped with the same reference and option code.

In the field this motor is selected for compact high-speed spindles where steady speed control and reliable starts under load are required. Maintenance teams commonly use the A06B-1406-B103 to replace motors showing bearing noise, repeated spindle alarms or thermal trips, restoring machine operation with minimal adjustments when the reference and option match.

For planned maintenance, many shops keep an identical spare motor on the shelf to limit machine downtime during changeover. It also serves well in retrofit tasks on older lines where the original FANUC Alpha i spindle specification must be preserved to keep tooling, parameters and cycle timing consistent.

Each unit can be tested by skilled engineers on CNC simulators with servo motors to verify feedback signals, thermal inputs and run performance before dispatch. Packaging is prepared for industrial transport, and the product is covered by warranty according to our service terms. Shipping timelines are managed to support maintenance windows, with fast dispatch depending on availability.

This model can be sourced as an emergency spare to reduce unexpected downtime. Cnc-shopping supports obsolete part sourcing as well as repair service or exchange service when applicable, helping keep legacy FANUC-based installations running. Worldwide supply options are available for maintenance teams and rebuild shops.

Frequently asked questions about A06B-1406-B103:

Which drive should be used with this Alpha i spindle motor?
Use a matching FANUC Alpha i spindle amplifier sized to the motor’s capacity. Always confirm the amplifier rating and motor nameplate to ensure correct pairing.

Is this a drop-in replacement for an existing A06B-1406-B103?
Yes when the existing motor carries the same option code B103. Compare the nameplate, connectors and mounting to confirm a direct swap without mechanical changes.

What does the 6/10000 marking indicate?
It denotes the family and speed class associated with approximately 10,000 rpm capability and the 5.5 to 7.5 kW power range. For exact torque and current values, refer to the motor nameplate and the machine’s documentation.

Can it replace older Alpha non-i spindle motors?
Alpha and Alpha i generations differ in feedback and amplifier interface. Direct substitution is not guaranteed, so review retrofit feasibility and consult your maintenance documentation before planning a swap.

What is the typical lead time?
This reference is generally available in 5 to 8 days depending on sourcing and inventory. Contact us for current availability, repair options or an exchange unit.
