Product Description:

The SF-A3.0093.030-14.056 is a servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. As a rotary actuator for industrial automation, it converts controlled electrical energy into precise mechanical motion for coordinated positioning or velocity control on packaging lines, handling robots, or machine tools. Its design pairs permanent-magnet excitation with closed-loop feedback, allowing rapid dynamic response and reliable repeatability during continuous operation.

The motor has a rated speed of 3000 rpm, and at this velocity the drive can provide repeatable service without thermal overrun. A torque constant of 1.35 Nm/A links drive current to produced torque and helps relate electrical input to motor output. The integrated holding brake is energized with 0.66 A at 24 VDC and supplies 10.0 Nm of static torque to keep vertical axes from drifting when power is removed. When current rises above nominal values, that torque constant helps indicate acceleration capability during profile moves. These values describe the relationship between current, brake operation, and available mechanical torque during motor use.

The motor uses IM B5 mounting, so the frame bolts to a flange rather than feet, and that flange measures 116 mm for compatibility with standard gearheads. The circular pilot helps maintain concentricity with gearboxes or belt pulleys, which can reduce runout during high-speed cycles. A smooth Ø19 × 40 mm shaft simplifies coupling while minimizing fretting on clamped hubs. Position data is supplied by an absolute encoder, allowing the control system to read rotor angle immediately after power-up. Two NTCs embedded in the windings provide temperature monitoring, and locked-rotor ratings of 6.0 A and 8.1 Nm indicate the motor’s limits during startup or stall events.
