Product Description:

The SF-A3.0093.030-04.000 is a servo motor produced by Bosch Rexroth Indramat and supplied within the SF Servo Motors series. As a rotary drive component, it converts controlled electrical power into precise shaft motion for positioning tasks in industrial automation cells, gantries, and packaging lines. The design includes an internal feedback encoder so the drive controller can monitor rotor position and regulate torque in real time. This integrated arrangement helps keep the motor compact while supporting accurate motion control on axes that require repeatable starts, stops, and speed changes.

The housing has an IP67 protection rating, so internal components remain sealed against dust and temporary water immersion. Mechanical mounting uses a 116 mm square flange that fits standard mounting patterns. With the brake omitted, the motor weighs 12 kg and has a maximum length of 287 mm, which helps keep moving-axis mass manageable. The steel shaft measures 19 mm by 40 mm and mates with keyed hubs or couplings. At a rated speed of 3000 rpm, the motor delivers torque in proportion to phase current, and its torque constant is 1.35 Nm/A. Rotor inertia is 16 × 10⁻⁴ kg·m², including encoder mass, which affects acceleration and deceleration behavior during rapid indexing moves.

An optional holding brake supports static loads after power is removed. When installed, it provides 10.0 Nm of holding torque at 120 °C and operates from a 24 VDC supply, with an engagement current of 0.66 A. The brake adds 0.60 kg to the motor weight and increases total inertia by 1.06 × 10⁻⁴ kg·m², so the axis response will change slightly compared with the non-brake version. During startup or stall conditions, the motor can reach a locked-rotor torque of 8.1 Nm while line current is limited to 6.0 A for thermal protection.
