SF-A4.0172.030-14.050

SF-A4.0172.030-14.050, manufactured by Bosch Rexroth Indramat, is part of the robust SF Servo Motors series designed for high-precision motion control. This motor incorporates an STG/MTG encoder for accurate feedback and delivers a Locked-rotor torque (M0) of 18 Nm. With a Rated speed (nN) of 3000 min^-1, it ensures consistent performance at nominal speed. The compact design includes a basic version shaft option and an integrated holding brake without requiring a mating connector.

In terms of detailed specifications, the motor achieves its start-up performance with a Locked-rotor current at M0 (I0) of 13 A, corresponding to its locked-rotor torque. It features a Torque constant (KT) of 1.38 Nm/A, directly relating torque output to current. The drive flange is sized at Flange size (SW): 142 mm to facilitate mounting in standard servo assemblies. The rotor's dynamics are optimized with a Mass without holding brake (m) of 19 kg, balancing inertia and responsiveness. Brake performance is specified with a Holding brake holding torque: 18 Nm (120°C) and a Holding brake mass: 1.04 kg for reliable load retention.

This servo motor integrates seamlessly into multi-axis systems, offering precise torque control and minimal settling times. The built-in holding brake enhances operational safety by securing the load at standstill, while the robust encoder feedback supports closed-loop stability. Overall, the SF-A4.0172.030-14.050 delivers dependable performance for robotics, packaging, and CNC applications, reducing engineering complexity and system downtime.
