Product Description:

The SF-A3.0068.030-00.000 is a brushless servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. Designed as a rotary actuator for positioning and velocity control tasks, it works with digital drives to deliver precise motion in industrial automation cells, pick-and-place modules, and packaging equipment. The motor integrates an optical encoder for feedback and suits machinery where compact size and sealed construction are required.

The motor is supplied from a DC bus of 670 V, enabling compatible inverters to reach its upper speed range. Position feedback comes from a digital encoder with 8 million increments per revolution of resolution, and the Single-turn (STG) design provides an absolute angle within one revolution without external homing sensors. A square flange of 116 mm matches common mounting patterns, and the combined rotor-encoder inertia of 11 × 10⁻⁴ kg·m² supports fast response with stable regulation. Under stall conditions, the windings draw 5.0 A of locked-rotor current, while a torque constant of 1.36 Nm/A relates commanded current to produced torque.

The housing measures 255 mm from the mounting face to the fan end, leaving room for tight axis arrays while retaining a rigid shaft of Ø19 × 40 mm for keyed couplings. When the rotor is blocked, it develops 6.8 Nm of static torque, which is suitable for indexing tables or clamp drives that require brief holding force before motion begins. An enclosure rating of IP67 allows operation in washdown or dusty areas when the circular connector seals are engaged, and the total mass of 9.0 kg supports handling during installation. Under continuous operation, the motor reaches a rated mechanical speed of 3000 rpm, matching common drive profiles for conveyors and servo presses while keeping temperature within the limits of the winding design.
