✅ 100% genuine Fanuc product. Brand new in original factory packaging. Ready for immediate worldwide shipment.
Why the Alpha i Series Is the Industry Standard for Fanuc CNC
Fanuc's Alpha i series motors are found in hundreds of thousands of CNC machines globally — from compact machining centers to large multi-axis turning centers. Three engineering characteristics make them the default choice for CNC axis replacement:
🔁 Closed-loop precision — The built-in high-resolution encoder provides accurate position and speed feedback directly to the Fanuc CNC controller, maintaining positioning accuracy even at high feed rates.
🔧 Low maintenance — Brushless AC design eliminates commutator wear, meaning the motor runs for years without scheduled maintenance under normal operating conditions.
⚡ Fanuc-native integration — Designed specifically for Fanuc servo amplifiers (Alpha i and Beta i series), the A06B-0213-B100 connects without parameter guesswork or compatibility issues.

💡 Before ordering: Confirm the full part number — including the -B100 suffix — matches the label on your existing motor. The suffix encodes shaft type, brake, and connector configuration. Substituting an incorrect suffix will result in a mechanical or electrical mismatch.
Decoding the A06B-0213-B100 Part Number
Understanding Fanuc's part number structure helps confirm you have the exact right motor:
A06B - 0213 - B100
│ │ └─ B100: Shaft/connector/brake specification code
│ │ ├─ B: Standard shaft with key, no brake
│ │ └─ 100: Connector type variant
│ └──────────── 0213: Motor model code (defines torque/speed/frame size)
└──────────────────────── A06B: Fanuc AC servo motor product family prefix
If your machine's motor label shows A06B-0213-B101 or A06B-0213-B200, those are different suffix variants — contact our team to verify before ordering.
Compatible Fanuc Servo Amplifiers
The A06B-0213-B100 is designed to operate with Fanuc Alpha i series servo amplifiers. Common compatible units include:
- A06B-6117-H103 (Alpha i SV 3/3/3 servo module)
- A06B-6120-H003 (Alpha i SVM servo module)
- A06B-6130-H003 (Beta i SVU standalone amplifier — verify capacity)
⚠️ Always match the servo amplifier's rated output capacity to the motor's rated power. Using an undersized amplifier will trigger overcurrent alarms (SV430/SV431 on Fanuc controllers).

FAQ — Fanuc A06B-0213-B100 Servo Motor
Q1: Is this a genuine Fanuc motor or an aftermarket alternative? This is a 100% genuine Fanuc A06B-0213-B100 — factory new and sealed. We supply only original Fanuc components. Aftermarket or clone motors carry significant risks in Fanuc systems: parameter mismatches, encoder signal errors, SV alarms, and accelerated mechanical wear are all common outcomes of non-genuine motor substitutions.
Q2: What does the "-B100" suffix mean, and can I substitute a different suffix? The B100 suffix defines the shaft configuration, connector type, and brake specification of the motor. B100 typically indicates a straight shaft with key, no electromagnetic brake, and a specific connector pin-out. Different suffixes (B101, B200, etc.) are physically or electrically different and are not interchangeable without modification. Always match the full part number including suffix from your machine's motor nameplate.
Q3: Which Fanuc servo amplifier should I pair with the A06B-0213-B100? The A06B-0213-B100 is designed for Fanuc Alpha i series servo amplifiers. The specific amplifier model depends on the axis configuration in your machine. Check your machine's servo parameter screen (Fanuc parameter No. 2020 — motor code) and electrical schematic to identify the matched amplifier. Our team can assist with amplifier identification if you provide your machine model and CNC series.
Q4: My Fanuc CNC is showing an SV alarm after motor replacement — what should I check? After installing a new A06B-0213-B100, verify the following: (1) Motor code parameter (No. 2020) is set correctly for this motor model; (2) Encoder cable is fully seated at both motor and amplifier ends; (3) Power cable phasing matches the original installation. Incorrect motor code parameters are the most common cause of SV alarms after genuine motor replacement.
Q5: Does the A06B-0213-B100 include an electromagnetic brake? The B100 suffix indicates this motor does not include an electromagnetic brake. If your application requires load holding — such as a vertical axis — you need the brake-equipped variant (suffix B200 or similar). Confirm the brake requirement from your machine's original motor nameplate before ordering.
Q6: Can this motor be used as a direct drop-in replacement? Yes — it is a direct replacement for any existing A06B-0213-B100 installation. Before installation, note down the original motor's serial number and back up the servo parameters from the CNC controller. A new motor does not retain previously set parameters, so having a parameter backup ensures fast re-commissioning.
Q7: How fast can you ship, and do you offer volume pricing? In-stock units are dispatched within 1–2 business days with worldwide express options for urgent maintenance situations. Volume pricing is available for machine builders, service companies, and MRO procurement teams — contact us via WhatsApp or the Enquiry button with your quantity requirements.
