SF-A4.0172.030-00.000

The SF-A4.0172.030-00.000, Bosch Rexroth Indramat, SF Servo Motors model is a high-performance servo motor combining precision and robustness. It features an integrated single-turn absolute STG/MTG encoder for reliable position feedback and a locked rotor current of 13 A delivering a locked rotor torque of 18 Nm. The motor operates at a rated speed of 3000 min⁻¹ and offers a torque constant of 1.38 Nm/A for responsive acceleration. Shaft options include a 24 × 50 mm output shaft with keyway and feather key, optimized for high-torque transmission.

Designed for demanding industrial environments, this unit presents a dimension of flange of 142 mm and a maximum length of 309 mm without the holding brake. It weighs 19 kg (mass without holding brake) and incorporates a moment of inertia of encoder of 40 × 10⁻⁴ kg·m² to minimize control lag. Temperature monitoring is handled by integrated negative temperature coefficient thermistors, while natural convection cooling maintains optimal thermal performance. Cable connections require a main cable cross-section of 4 × 1.5 mm² and brake cable of 2 × 1.5 mm².

Engineered for seamless integration, the SF-A4.0172.030-00.000 is rated to IP67 (excluding the output side) for protection against dust and water ingress, ensuring dependable operation in harsh conditions. The optional holding brake with a moment of inertia of 3.1 × 10⁻⁴ kg·m² prevents axis drift and enhances safety during power-off scenarios. Ideal for robotics, CNC machining, and automated packaging lines, this servo motor accelerates commissioning and reduces maintenance, delivering consistent precision in high-throughput applications.
