Product Description:

The SF-B5.0250.020-10.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It is built to supply rotary motion within automated machinery, converting electrical energy from a drive into controlled mechanical torque for positioning axes or continuous-duty spindles in production lines. This arrangement suits equipment that requires repeatable rotation, stable speed regulation, and accurate response to changing load commands.

During operation, the motor runs at a rated speed of 2000 min⁻¹, giving control systems a predictable velocity ceiling. When the shaft is prevented from rotating, the motor can apply a locked-rotor torque of 23 Nm while the windings draw a locked-rotor current of 10 Arms. This operating point supports safe startup under stall conditions. A torque constant of 2.3 Nm/A links drive current to output torque, which helps keep current-to-torque behavior straightforward. Position feedback is produced by a single-turn absolute encoder with a resolution of 8,000,000 incr./rev., allowing the controller to command fine angular steps while supporting closed-loop speed control down to standstill. The bearings can also carry axial thrust loads up to 380 N without reducing positioning accuracy.

A flange size of 190 mm matches standard gearbox and machine interfaces, and the housing mass of 24 kg adds thermal mass for heat dissipation while remaining manageable during handling. Dynamic response is influenced by a rotor moment of inertia of 83×10⁻⁴ kg·m², which supports quick acceleration without excessive drive current demand. The unit withstands transport or operating shocks up to 6 g, helping protect the encoder electronics, which maintain an accuracy of ±20 arcsec. Mechanical integration is also supported by the 300 mm overall length and a Ø32 × 58 mm shaft that accepts standard couplings.
