Product Description:

The SF-B5.0250.030-00.019 is a servo motor built by Bosch Rexroth Indramat for the SF Servo Motors series. This brushless unit works with Rexroth digital drives to deliver closed-loop rotary motion for packaging, cutting, and material-handling axes that require repeatable positioning and steady speed control. Its integrated absolute encoder provides position data as soon as power is applied, so the connected machine can return to operation without a homing cycle. That arrangement helps the motor fit automated systems where quick restarts and accurate axis synchronization are important during normal production.

The motor reaches a rated speed of 3000 rpm, which supports short cycle times in indexing and pick-and-place tasks. With a torque constant of 1.44 Nm/A, the drive controller can estimate load torque directly from phase current for stable regulation during changing demand. Position feedback is generated by a single-turn device that resolves 8 million increments per revolution and maintains an accuracy of ±20 arcseconds, which supports smooth contouring and fine registration. During clamping or emergency stops, the shaft can withstand a locked-rotor torque of 23 Nm, while peak current reaches 16 A from the power stage. A size 1, 6-pin connector and a 4 x 2.5 mm² motor cable simplify wiring and help control voltage drop over longer cable runs.

The housing weighs 24 kg, which adds stiffness and helps reduce vibration when acceleration rates are high. An enclosure rating of IP67 protects the windings and encoder electronics against dust and temporary immersion, making the motor suitable for areas where moisture or coolant exposure may occur. Power is transferred through a 32 mm × 58 mm shaft, and the rotor inertia of 83 × 10⁻⁴ kg·m² supports a balance between dynamic response and load stability. The motor also has a 190 mm flange and a 300 mm overall length, which helps it fit multi-axis machines where mounting space and cable routing must stay controlled.
