Product Description:

The SF-A2.0041.030-14.053 servo motor is produced by Bosch Rexroth Indramat for the SF Servo Motors series. It serves as a compact rotary actuator that converts regulated DC bus energy from a matched drive into precise motion for automated packaging lines, assembly robots, and conveyor stations. In closed-loop axis systems, it supports accurate starts, stops, and repeatable positioning during frequent machine cycles. An integrated spring-applied holding brake keeps the load in position during power-off intervals, making the unit suitable for vertical axes and controlled stopping functions in industrial automation cells.

During continuous operation, the motor attains a rated speed of 3000 rpm while the drive maintains a DC bus voltage of 670 VDC. The electromagnetic design features a torque constant of 1.43 Nm/A, providing predictable torque scaling and helping current demand translate consistently into shaft torque. Under nominal excitation, the shaft can sustain 3.2 Nm of torque. Brake engagement requires 24 VDC; when energized, it draws 0.56 A, adds 0.35 kg to the housing, and contributes 0.4 × 10⁻⁴ kg·m² to combined inertia. Mechanical mounting follows the IM B5 flange pattern, simplifying alignment to gearboxes or direct-drive stages. Acoustic emission does not exceed 58 dB(A), which supports installation near work areas where machine noise must remain controlled.

For startup and emergency stopping, the inverter can deliver a stall current of 2.8 A, producing a locked-rotor torque of 4.0 Nm until motion begins. Speed changes are assisted by a rotor inertia of 6 × 10⁻⁴ kg·m², and the separate brake inertia helps keep axis response predictable during acceleration and deceleration. The assembly endures shocks up to 6 g, helping the motor tolerate transport loads and abrupt machine stops.
