Product Description:

The SF-A4.0230.060-10.000 is a servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. It is intended for closed-loop motion control in industrial automation, where precise speed and position regulation are required to coordinate machine axes and tooling. This type of motor is commonly used where repeatable motion and stable feedback are needed for synchronized machine operation.

It mounts in an IM B5 orientation, so the stator flange seats against the machine wall while the smooth shaft passes through a face opening. The flange diameter is 142 mm, and the pilot uses a Ø130 j6 centering recess for accurate alignment. A Ø24 k5 × 50 mm shaft provides a tight press fit to couplings. At startup, the motor can deliver 22 Nm of locked-rotor torque while drawing 25 A of stall current, which helps match the motor to the drive. During continuous operation it reaches a rated mechanical speed of 6000 rpm. The drive sets torque with a constant of 0.88 Nm/A, allowing linear current-to-torque conversion across the control range. The overall length is 341 mm, which helps the motor fit typical enclosure depths while still providing room for the windings.

For high-resolution feedback, the integrated encoder supplies 8 million incr./rev., and this supports accurate position monitoring during controlled motion. The rotor inertia is 54 × 10⁻⁴ kg·m², which affects acceleration behavior and load response. The axial load limit is 154 N for thrust along the shaft centerline. Static mass is 22 kg without a holding brake, which is useful when planning mounting support. A DIN 332-DS M8 center hole in the shaft nose accommodates puller bolts for safer removal during service. The stated encoder accuracy window and shaft-end provisions support precise installation and reliable positioning without adding unnecessary mechanical complexity.
