Product Description:

The SF-A5.0460.030-14.030 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a brushless rotary actuator, it converts drive controller output into controlled mechanical motion for positioning, velocity, or tension loops in automated machinery. The motor frame follows the IM B5 construction form, so it mounts directly to a flange without foot supports. An integrated holding brake and a closed frame allow the unit to secure axial loads when power is removed while keeping external dimensions compact for cabinet or machine-side installation.

During continuous operation, the unit reaches a rated speed of 3000 rpm under nominal voltage and load. The torque constant of 1.58 Nm/A links phase current to developed torque and supports drive tuning for proportional control. When the shaft is prevented from turning, a locked-rotor current of 29 A can flow and the motor produces a stall torque of 46 Nm; these figures set inverter current limits and mechanical coupling requirements during starts. Heat is removed solely by natural convection, so airflow around the housing must remain unobstructed. The acoustic emission remains at or below 58 dB(A), supporting installation near operators without additional sound shielding.

The permanent brake contributes a holding torque of 56 Nm to secure the axis against gravity or process forces once motion stops. It is energized by a supply of 24 VDC; during release, the coil draws 1.33 A and the armature lifts within 97 ms, allowing a rapid transition between static and dynamic states. Repetitive emergency stops are absorbed through a plug-brake energy capacity of 4085 Ws, working with an external resistor of 1.0 Ω to dissipate thermal loads. The motor also has a shock rating of 6 g, allowing it to tolerate transport or machine impacts without performance loss.
