Product Description:

The SF-A3.0093.030-10.000 is a servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. The unit converts regulated three-phase drive power into controlled rotary motion for packaging lines, pick-and-place modules, and general positioning axes. Its integrated absolute encoder returns real-time rotor position to the controller, and the sealed housing allows the motor to be mounted directly on machinery without auxiliary enclosures. The compact form also suits installations where axis space is limited and repeatable positioning is required over long operating cycles.

Its primary operating point is 3000 rpm, giving linear stages predictable velocity when commanded by a drive. The square face measures 116 mm, and the body length of 287 mm fits inside tight mechanical envelopes. A rotor inertia of 16 × 10⁻⁴ kg·m² supports quick acceleration while helping smooth load changes, and the total mass of 11 kg adds thermal capacity for continuous duty. The torque constant is 1.35 Nm/A, which allows a direct relationship between commanded current and produced torque. During a locked-rotor test, the windings draw 6.0 A to generate 8.1 Nm, and those values indicate the expected peak demand on the matching amplifier. A 19 mm diameter shaft with a 40 mm length passes torque to couplings or timing pulleys without intermediate reduction.

The bearing set endures axial thrusts up to 133 N, so the motor can carry moderate screw or belt preload without premature wear. Feedback is supplied by a single-turn absolute encoder with a resolution of 8 Million Incr./Rev. and an accuracy of ±20 Angular Seconds, which supports precise position tracking through the full revolution. The stator, connectors, and seal system are rated IP67, preventing dust intrusion and allowing washdown exposure in suitable machine layouts. This arrangement helps protect the feedback system and internal components when the motor is used on compact actuators in wet or dirty production areas.
