Product Description:

The SF-A3.0093.030-00.050 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the SF Servo Motors series. Designed for closed-loop positioning and speed control, it converts drive current into controlled torque for axes in assembly lines, pick-and-place gantries, and other automated stations. It operates with a compatible controller and power stage to deliver precise rotary motion during indexing, transfer, and synchronized feed tasks. Its sinusoidal back EMF supports smooth torque production across the usable speed range.

During standard operation, the motor reaches a rated speed of 3000 rpm, allowing gearless coupling to many ball-screw and belt transmissions. This speed suits direct-coupled motion systems that need fast response without adding a gearbox. The torque constant is 1.35 Nm/A, so drive current produces predictable output torque. At startup, the stator can draw a locked-rotor current of 6.0 A and produce a stall torque of 8.1 Nm, which helps overcome static friction before movement begins. The drive requires a DC link voltage near 670 V for normal operation, and the sinusoidal back EMF design helps reduce torque ripple and acoustic noise.

Mechanical mounting follows IM B5, so the flange mounts directly to a machine frame and supports straightforward face mounting. The shaft can accept axial loads up to 133 N without disturbing alignment during operation. Deep-groove bearings with a service life of 20,000 hours support that load and the radial forces generated at full speed. The rotor and housing can withstand shocks of 6 g, which is useful in equipment exposed to intermittent impact or machine vibration. Thermal supervision is provided by an embedded PTC thermistor that changes resistance from -5 °C to 155 °C, giving the controller a reliable overtemperature signal. Wiring uses user-supplied plugs because a mating connector is not included.
