SF-A4.0230.030-04.050

The Bosch Rexroth Indramat SF-A4.0230.030-04.050 from the SF Servo Motors series features a torque at locked rotor condition of 22 Nm and draws a locked rotor current of 14 A at standstill, providing reliable starting performance. This motor integrates an STG/MTG absolute encoder for high-resolution position feedback, enabling accurate closed-loop control in demanding applications. Thermal management relies on a passive natural cooling type that eliminates the need for additional fans or liquid circuits, simplifying installation and maintenance. Power and brake connections are standardized with a motor cable cross section of 4 x 2.5 mm² and a holding brake cable of 2 x 1.5 mm², ensuring consistent electrical interfaces across the SF lineup.

Mechanically, the SF-A4.0230.030-04.050 spans a max length of 388 mm and weighs 23.7 kg, striking a balance between structural rigidity and compact design for space-constrained cabinets. It withstands radial loads up to approximately 810 N at 60 mm flange distance and an admissible axial load of 154 N, supporting both static and dynamic force requirements in rotary and linear actuators; these values are validated by dynamic testing protocols to ensure bearing longevity under high-speed cycling. The integrated holding brake, actuated via its dedicated 2 x 1.5 mm² cable, secures the load in power-off conditions, enhancing system safety through controlled deceleration. Compliance with the established SF motor series mechanical dimensions ensures drop-in compatibility with existing mounts and couplings.

Installation benefits from the SF series' uniform shaft design, which includes a keyway and feather key for direct coupling to gearboxes or pulleys without additional modifications. The combination of natural cooling and robust load ratings provides stable thermal equilibrium and long-term reliability under cyclic operational profiles. Altogether, the SF-A4.0230.030-04.050 servo motor delivers dependable torque density, precision feedback, and simplified integration for advanced motion-control systems.
