Product Description:

The SF-A4.0230.030-00.019 is a brushless servo motor manufactured by Bosch Rexroth Indramat and supplied within the SF Servo Motors series. It serves as an electromechanical actuator that delivers closed-loop rotary motion for packaging lines, material-handling modules, and other automated stations. When paired with a compatible drive controller, the motor converts regulated electrical power into precisely controlled shaft rotation so mechanical loads follow programmed speed and position profiles in real time. Its brushless design also supports repeatable operation with reduced wear at the commutation point.

The motor requires a DC link supply of 670 V, which provides the voltage needed for rapid acceleration. During a locked-rotor event, the winding draws 14 A, and at the same standstill condition it can produce a stall torque of 22 Nm. Under continuous duty, the shaft reaches 3000 rpm, matching common gearbox ratios without exceeding rated limits. A torque constant of 1.57 Nm/A gives a linear relationship between phase current and produced torque, which helps the drive respond predictably to command changes. Position feedback is handled by an integrated absolute-value encoder that provides immediate multi-turn data after power-up, allowing the axis to report position without a separate homing routine.

Mechanical integration follows the IM B5 construction, which places the mounting flange at the drive end while the keyed shaft mates directly with couplings. Heat is removed by natural convection, so unobstructed airflow around the housing is required. The motor’s acoustic emission does not exceed 58 dB(A), which helps keep nearby work areas quieter during normal operation, and the assembly withstands transport or emergency-stop shock up to 6 g. Thermistors embedded in the stator provide temperature-based shutdown signals, and the mating power connector is not included so cable termination can be matched to the installation layout.
