Product Description:

The SF-A3.0093.030-00.50 belongs to the SF Servo Motors series produced by Bosch Rexroth Indramat. This permanent-magnet synchronous unit serves as a rotary actuator in industrial automation, supplying closed-loop position and speed control for packaging axes, pick-and-place modules, and light machining spindles. Its flange and shaft dimensions follow the IEC pattern, allowing direct coupling to gearboxes or other driven components without custom adapters.

At a rated speed of 3000 rpm, the motor delivers continuous rotation suitable for medium-duty cyclic tasks. The electromagnetic design yields a torque constant of 1.35 Nm/A, so drive current can be matched to expected torque output in a straightforward way. Feedback is supplied by a single-turn absolute encoder with 8 million incr./rev. of resolution and an accuracy of ±20 arcsec, which supports precise positioning without external scales. The housing has an IP67 protection rating that helps keep out dust and withstand temporary immersion. The feedback stack adds only 16 × 10⁻⁴ kg·m² of inertia, which helps preserve responsive acceleration. A Ø19 × 40 mm shaft with an A6 × 6 × 32 feather key transfers torque to the load, and the 287 mm overall length helps the motor fit in compact machine layouts.

During startup or jam conditions, the motor can produce a locked-rotor torque of 8.1 Nm while drawing a locked-rotor current of 6.0 A. Static loads are limited by a maximum axial shaft force of 133 N, so belt tension or thrust loads must stay within that limit. The assembly weighs 12 kg, which gives the unit a solid mechanical presence while remaining suitable for compact axis layouts. Internal construction tolerates impacts up to 6 g, supporting installation on mobile equipment or machinery that is exposed to vibration. These operating limits help the motor maintain stable motion performance in demanding industrial use.
