Product Description:

The SF-A3.0068.030-00.015 servo motor is built by Bosch Rexroth Indramat within the SF Servo Motors series. It is a permanent-magnet synchronous device designed to provide controlled torque and velocity for closed-loop axes in automated machinery. Using an IM B5 flange construction, the motor seats against flat mounting surfaces while its front shaft couples directly to gearboxes, ball screws, or timing pulleys. This arrangement allows a compact rotary actuator to be installed wherever precise electronic motion is required without adding intermediate transmission components.

The electrical side is tailored to a DC bus of 670 V, so the connected drive must supply that level of voltage to reach the motor’s performance range. At a rated speed of 3000 rpm, the rotor produces mechanical power while staying below acoustic emissions of 58 dB(A). Startup demands are reflected by a locked-rotor current of 5.0 A, and the associated locked-rotor torque of 6.8 Nm is the maximum static load the shaft can oppose during indexing or clamp engagement. Ongoing torque generation scales linearly with current according to a constant of 1.36 Nm/A, allowing the drive to predict output accurately and limit phase current before magnetic saturation occurs.

The housing has an IP67 rating, allowing operation in washdown areas where dust and temporary immersion are present. A flange diameter of 116 mm positions the stator and aligns the shaft with the pilot land. Motion feedback is handled by an optical encoder that supplies 8 million increments per revolution with a single-turn precision of ±20 arcsec. These values let the controller resolve very small angular movements when the motor is coupled to fine-pitch screws. Two NTC sensors supervise winding temperature, and the mechanical structure tolerates 6 g shocks while maintaining encoder calibration during transport and service.
