A06B-0571-B355

The A06B-0571-B355 from FANUC is a high-quality AC servo motor engineered for precision applications. With a continuous power rating of 3.5 kW, this motor ensures efficient performance, while its rated stall torque reaches 25 Nm, translating to a force of 255 kgf·cm. Operating at a nominal rotational speed of 3000 min⁻¹, this motor is designed for dynamic and responsive applications.

The motor's peak theoretical torque is a substantial 74 Nm, allowing for significant power during demanding tasks. It features a rotor inertia of 0.0054 kg·m², which contributes to rapid acceleration and deceleration. The motor can achieve a maximum calculated acceleration of 13,600 rad/s², suitable for high-speed operations. Continuous RMS current is rated at 37 A, while the torque constant is fixed at 0.66 Nm/A, facilitating effective torque management.

The back-EMF constant of 23 V per 1000 min⁻¹ provides valuable feedback for accurately controlling motor speed, with an armature resistance of 0.049 Ω. Quick response times are ensured by a mechanical time constant of just 0.001 seconds, complemented by a thermal time constant of 30 minutes for heat regulation under extended use. For demanding conditions, the motor supports peak permissible currents of up to 200 A, allowing for powerful performance during critical operations.
