Product Description:

The SF-B5.0250.030-10.067 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for closed-loop motion systems in assembly lines, packaging stations, and material-handling cells, where the motor converts current from a matching drive into controlled mechanical torque for rotary axes. In these systems, it supports repeatable rotary motion for indexing, transfer, and positioning tasks that rely on continuous feedback from the drive. Its permanent-magnet synchronous design works with the drive’s switching pattern to support accurate speed and position regulation in general industrial automation.

Electrical performance is based on a DC link of 670 V, which provides the energy reserve needed for rapid torque transients. At a rated speed of 3000 rpm, the motor develops torque in proportion to current with a constant of 1.44 Nm/A. During startup or stall, it can draw 16 A and produce a locked-rotor torque of 23 Nm. Those values describe the current demand and available breakaway torque when the shaft is not yet moving. Electronic commutation works with the motor’s back EMF to reduce torque ripple, while an absolute multi-turn encoder returns clear position data to the drive. Power and feedback lines terminate on a sealed plug-in connector, which keeps the electrical interface compact and protected.

Mechanical integration follows the IM B5 construction code, so the motor uses a flange-mounted arrangement with the shaft facing outward for direct coupling. In this arrangement, the flange supports the radial load while the output shaft remains accessible for connection to couplings or driven mechanisms. The stator housing is machined from aluminum, which helps reduce weight and thermal inertia. Two integrated temperature sensors rated as 2 x NTC report winding temperature to the drive before overheating can develop during operation. The motor also has a sinusoidal back EMF, allowing current controllers to apply sine-wave excitation for smoother running, lower acoustic noise, and improved efficiency.
