The FANUC A06B-0257-B705 AC servo motor is engineered for high-performance applications. With a rated output of 1.0 kW, it operates at a maximum speed of 3000 RPM. This unit is powered by a voltage of 90V DC and draws a current of 7.5 A. The motor reaches a peak torque of 3.8 Nm while maintaining a rated torque of 0.3 Nm, which aids in providing effective motion control.

This motor features a shaft diameter measuring 14 mm and has four poles, which contributes to its operational characteristics. The inertia rating is noted at 0.014 kg·m², indicating its responsiveness and efficiency during operation. Constructed as a synchronous motor with permanent magnets, it ensures reliable energy usage and consistent performance in various settings.

Critical to its functionality is the incremental encoder integrated with an encoder resolution of 2500 PPR, which offers precision in motor positioning and movement feedback. The overload capacity of this unit allows it to sustain 150% of its rated torque for up to three seconds, accommodating sudden spikes in demand. It also incorporates a 90V DC brake type for effective stopping control, making it a versatile choice for industrial automation and robotic functions.
