Product Description:

Bosch Rexroth Indramat produces the SF-A4.0230.030-14.050 servo motor as part of its SF Servo Motors series. This rotating actuator is intended for CNC axes, pick-and-place heads, and other machinery that require precise, closed-loop motion. Electrical power from a drive amplifier is converted into torque at the shaft while integrated sensors deliver position feedback for control algorithms. The motor’s flange and shaft geometry fit common mechanical standards, allowing straightforward mounting in automation frames and transmission assemblies without additional adapters.

The holding brake is energized with 24 VDC and draws 0.7 A, permitting a compact cable gauge while still delivering static torque. After power removal, the brake engages within 25 ms, and it releases in 50 ms when voltage is restored. The brake can absorb a reflected inertia of 3.1 × 10⁻⁴ kg·m², and it clamps the rotor with 18 Nm so suspended loads remain stationary during power-off events. The motor also has a locked-rotor current of 14 A and a locked-rotor torque of 22 Nm, which indicate the demand placed on the drive during starting and overload conditions.

The motor has a rated speed of 3000 rpm, and torque is produced in proportion to the electromagnetic coupling of 1.57 Nm/A. With the encoder installed, the total rotational inertia is 54 × 10⁻⁴ kg·m², balancing dynamic response against stability for mid-mass loads. The square flange measures 142 mm, while the overall body length with the brake is 388 mm, which helps verify cabinet depth and stack clearances. A 24 mm diameter, 50 mm long shaft transfers torque to couplings or pulleys without additional sleeves, and these dimensions can be checked against permissible radial loads and the intended duty cycle.
