Introduction
Elevate your CNC machining and robotic automation with the Fanuc A06B‑0075‑B403 servo motor. Tailored for precision-driven industries, this motor bridges the gap between raw power and surgical accuracy, making it an ideal choice for high‑load milling, multi‑axis turning, and sophisticated pick‑and‑place systems.

Relevant Entities & Technologies
Built around a brushless DC core, it features a 20‑bit absolute optical encoder, advanced sinusoidal commutation, and PWM drive compatibility with Fanuc αi/αiA series controllers. The die‑cast aluminum housing meets IP65 standards, while Class F insulation ensures stable operation under thermal stress.

Micro‑Level Specifications

• Continuous Torque: 3 Nm for steady-state cutting

• Peak Torque: 9 Nm to handle rapid acceleration

• Nominal Speed: 3000 rpm for consistent cycle times

• Rotor & Bearings: Low‑inertia rotor paired with dual angular‑contact bearings for minimal vibration

• Feedback System: Zero‑homing absolute encoder for instant position recall

  Materials & Design Highlights

  The hardened stainless steel shaft and precision‑wound copper coils reduce cogging and enhance responsiveness—even at low speeds. The motor’s streamlined winding layout maximizes heat dissipation, protecting the Class F insulation during prolonged heavy loads.

  Advantages

  By integrating the A06B‑0075‑B403, you’ll notice smoother contouring on complex parts, faster tool‑change cycles, and fewer thermal distortions. Its robust IP65 rating minimizes downtime on dusty or splash‑prone shop floors, while plug‑and‑play support for Fanuc 30i/31i controls reduces installation headaches.

  FAQ

  How does the B403 differ from the B103 variant?
  The B403 delivers roughly 20% more continuous torque than the B103, making it better suited for heavier tooling or robotic joints.

  Is active cooling required?
  Standard ambient cooling suffices for most applications, but forced-air or liquid cooling kits are available for extreme duty cycles.

  What safety standards does it comply with?
  Meets ISO 13849 safety requirements when paired with certified Fanuc drives and controllers.
