Description
The part number A06B-6151-H045 is a spindle amplifier module made by FANUC, used in CNC machines to control high-power spindle motors.
🔧 Description
- Type: Spindle Amplifier (AC Spindle Drive)
- Series: FANUC αi (Alpha i) Spindle Amplifier Series
- Model family: AiSP-45HV
- Voltage class: 400V industrial spindle drive
⚙️ Function
- Drives the main spindle motor in CNC machines
- Converts CNC controller commands into controlled power output
- Regulates:
- Spindle speed (RPM)
- Cutting torque
- Acceleration and braking
👉 In simple terms: it is what makes the machine’s main cutting spindle rotate with controlled power and precision.
📊 Key technical idea (typical for H045 class)
- Medium–high power spindle amplifier (around 45 kW class)
- Designed for heavy-duty CNC machining
- Uses feedback from spindle motor sensors for precise control
- Built-in protection (overcurrent, overheating, fault diagnostics)
🏭 Where it is used
- CNC machining centers
- Heavy CNC lathes
- Milling and boring machines
- Industrial production lines requiring high spindle torque
🔁 Where it sits in the A06B-6151 range
- H006 → low power spindle (small machines)
- H011–H015 → medium power
- H030 → medium-high power (~30 kW)
- H045 → high power (~45 kW class, heavy machining)
- Higher models (H075/H100) → very high power industrial spindles
✔️ Simple summary
A06B-6151-H045 = FANUC αi spindle amplifier (~45 kW class) used to control the main spindle motor in heavy CNC machining systems.
