Product Description:

The SF-B5.0250.030-10.000 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. In industrial automation, it serves as a rotary actuator that delivers controlled acceleration, deceleration, and holding torque so that machine axes can follow programmed motion profiles with low positioning error during indexing, transfer, and synchronized feed movements. Integrated encoder feedback and a compact housing make the motor suitable for medium-sized machinery cells where stable speed regulation, repeatable stopping behavior, and reliable position tracking are required across frequent start-stop cycles.

At a rated speed of 3000 rpm, the rotor supports short cycle times in fast-moving automation equipment. The motor has a torque constant of 1.44 Nm/A, so available phase current can be related directly to developed torque during current-controlled operation. During a locked-rotor event, the motor can withstand 23 Nm while drawing 16 A, which gives the controller clear values for overload monitoring and protective thresholds. A square 190 mm mounting flange helps align the stator with gearbox or machine frame surfaces. The built-in single-turn absolute encoder supplies position data with ±20 arc-seconds of precision, which supports accurate commutation and repeatable axis positioning after power-up.

The rotor inertia of 83 × 10⁻⁴ kg·m² supports a balance between quick speed changes and stable response when the driven load changes. Overall mass is 24 kg, which gives the motor a solid installed presence without making handling unusually difficult for its class. Motion feedback resolution reaches 8 million incr./rev., allowing very fine incremental positioning and smooth command updates during servo control. Mechanical power is transferred through a steel shaft sized at Ø32 × 58 mm, which accepts standard couplings without requiring sleeves. This shaft size also provides a secure interface for torque transmission into gearboxes, pulleys, or direct-coupled machine elements.
