Product Description:

The SF-A2.0041.030-10.053 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It is intended for closed-loop motion tasks in industrial automation where precise speed and position control are critical. The motor couples directly to driven shafts, which can reduce the need for belts or reduction stages in assembly lines, packaging equipment, or light machining centers. Because the rotor is controlled through feedback, the motor can support synchronized indexing, speed regulation, and repeatable positioning with minimal lost motion.

Its electromagnetic performance includes a torque constant of 1.43 Nm/A, so each additional ampere of stator current produces 1.43 newton-meters at the shaft. Under continuous duty, the rotor sustains a rated speed of 3000 rpm, which suits common spindle and feed-rate ranges. When the shaft is mechanically locked, the motor can hold 4.0 Nm while the phase windings draw 2.8 A rms. The windings are designed for a DC link potential of 670 V, and two integrated NTC sensors send temperature data to the controller for overload monitoring. This temperature feedback helps the drive react to heat buildup during repeated acceleration or prolonged low-speed operation.

The housing uses the flange-mount layout identified as IM B5, giving a precise mounting face for gearboxes or machine frames. Heat from the stator is dissipated by radiation and natural convection, so external fans or liquid circuits are not required. During handling or operation, the assembly tolerates shocks up to 6 g, which supports use on machinery with intermittent vibration or abrupt motion changes. Its airborne noise does not exceed 58 dB(A), which helps when low operating noise is preferred around production equipment. The self-contained cooling method also keeps installation simpler because no separate airflow hardware or coolant connections are needed.
