SF-A4.0091.030-10.050

The Bosch Rexroth Indramat SF-A4.0091.030-10.050 from the SF Servo Motors series features a single-turn (STG) encoder system and an insulation classification F design that ensures reliable operation in demanding environments. It delivers a rated speed of 3000 RPM with a precise torque constant of 1.42 Nm/A, facilitating high responsiveness and repeatable motion control. With a robust locked-rotor torque of 10 Nm and a smooth startup supported by a locked-rotor current of 7.0 A, this servo motor prevents stalling under heavy loads. Designed for digital integration, it seamlessly pairs with the fully digital Servodyn-D inverter system for advanced commutation and field-oriented control.

Mechanically, the motor’s lightweight mass of 13 kg (without holding brake) and compact maximum length of 246 mm (without holding brake) simplify installation in space-constrained drive cabinets. The high-precision bearings boast a minimum service life of 20,000 hours, delivering long-term stability and reduced downtime. An IP 67 protection type rating (excluding the output side) wards off dust ingress and withstands immersion up to 1 m for 30 minutes, while the aluminum frame provides superior heat dissipation without complex cooling circuits. The simplicity of the mechanical design and the absence of additional cooling fans contribute to reduced maintenance requirements and higher mean time between failures.

Optimized for high-frequency, precision applications, the SF-A4.0091.030-10.050 offers dependable performance across automation platforms. Its minimal maintenance profile and robust construction ensure consistent throughput in packaging, assembly, and material handling systems. The combination of digital encoder feedback, durable bearing life, and IP 67-rated protection makes this servo motor a solid choice for engineers seeking a balance of efficiency, longevity, and precise motion control.
