Product Description:

The SF-B4.0230.060-10.049 is a servo motor manufactured by Bosch Rexroth Indramat in the SF Servo Motors series. It is intended for integration into industrial automation cells where accurate rotary positioning is required, such as indexing tables and Cartesian gantries. An integrated single-turn absolute encoder continually reports rotor angle, enabling the connected drive controller to close the motion loop without an external reference switch. This arrangement also supports stable trajectory control during rapid load changes and repeated positioning cycles.

The motor draws a continuous torque-producing current of 25 A rms at standstill, so the connected drive must be sized for that electrical demand. High-resolution feedback is available because the encoder produces 8,000,000 Incr/Rev, permitting fine incremental motion and tight velocity regulation. Position deviation is limited by an accuracy of ±20 Arcsec, which helps reduce accumulated error in coordinated multi-axis systems. Mechanical resilience is shown by a shock rating of 6 g, allowing the housing to tolerate transport shock and abrupt machine motion. The shaft can accept an axial thrust load of up to 154 N, which is useful where couplings or belt systems apply end load to the rotor. Mounting uses a 130 mm flange diameter, which fits common machine interfaces for this frame size.

During operation, acoustic emissions remain below 58 dB(A), which supports installation in production areas without additional sound enclosures. The smooth output shaft has a diameter of 24 mm and is suited for clamp couplings that help minimize backlash. Power conductors should be routed through a 4 x 6.0 mm² cable, and the stated cable mass of 0.49 kg/m helps when planning moving-cable support. Two embedded NTC sensors relay winding temperature to the drive for thermal monitoring during load changes and repeated starts. A size 1.5 circular connector combines power and signal contacts, which helps keep motor-side wiring compact.
