Product Description:

The SF-B5.0250.030-00.000 is a servo motor built by Bosch Rexroth Indramat for the SF Servo Motors series. Designed for closed-loop positioning and velocity control in automated machinery, the unit converts electrical input from a drive into mechanical shaft rotation for packaging, assembly, and material-handling axes. The motor is suited to applications that require repeatable starts, stops, and controlled speed changes during normal operation. It works within an integrated drive system where accurate feedback, high dynamic torque, and compact dimensions are important.

In operation, the motor reaches a rated speed of 3000 rpm, allowing coordinated motion across a broad range of servo-driven tasks. Electromagnetic output rises in proportion to a torque constant of 1.44 Nm/A, so each ampere of phase current produces a predictable amount of shaft torque. The motor delivers a locked-rotor torque of 23 Nm while drawing 16 A at startup. Rotor inertia is 83 × 10⁻⁴ kg·m², which supports responsive acceleration while helping maintain stable load control. Position feedback is supplied by a single-turn absolute encoder with a resolution of ±20 arc-seconds and 8 million increments per revolution, enabling fine interpolation inside compatible drive controllers. Connector size 1 simplifies plug-in power and feedback wiring, and the 4 x 2.5 mm² motor cable cross-section matches common servo harness layouts.

The motor uses a mounting flange of 190 mm, and the shaft is machined to 32 × 58 mm for compatibility with standard couplings. Overall body length is 300 mm, and the housing supports a DC-link voltage rating of 670 V, allowing the motor to pair with high-bus-voltage drives while reducing current demand for the same power level. With a mass of 24 kg, the unit adds a substantial load that should be considered in the mounting arrangement. Power and feedback connections are routed through dedicated connectors, which helps keep cable entry organized and leaves internal cooling paths unobstructed.
