Product Description:

The SF-A2.0041.030-14.037 is a servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It delivers closed-loop rotary motion for production cells, indexing tables, and other automated machinery that depend on precise speed and position regulation. Its electromechanical design couples directly to planetary gearboxes or timing pulleys to translate drive commands into repeatable motion. The motor is intended for servo systems that require controlled acceleration, steady running speed, and accurate stopping during repeated operating cycles.

The motor reaches 3000 rpm at its rated operating point, a speed suited to medium-inertia axes that require fast indexing. Its electromagnetic design yields a 1.43 Nm/A torque constant, allowing the drive controller to relate phase current directly to motor torque. The shared bus can supply a 670 VDC DC link, which supports the power stage during normal operation and regenerative events. Position feedback comes from an absolute encoder that provides 8 million increments per revolution and an accuracy of ±20 angular seconds, so fine incremental moves remain repeatable. When power is removed, the integrated holding brake clamps the shaft with 3.2 Nm of torque. The motor uses IM B5 flange mounting for direct face attachment to compatible machine structures.

The housing has a protection rating of IP67 excluding the output flange, so washdown spray will not reach the internal windings while the coupling area remains open for alignment. The brake circuit operates on 24 VDC and draws 0.56 A during release. During startup tuning, the drive may command 2.8 A with the rotor locked, producing 4.0 Nm of standstill torque for stiffness checks. Dual NTC sensors monitor winding temperature, and operation is limited to an ambient temperature of 40 °C. This temperature monitoring allows the drive to react if winding heat rises too high during operation.
