Product Description:

The SF-B5.0460.020-14.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It is intended to produce controlled rotary motion in automated axes where precise speed regulation and quick torque rise are required. By pairing with a compatible drive, this motor converts commanded currents into mechanical work so that indexing tables, gantries, or packaging stations can follow programmed profiles without position error.

The electromagnetic section is optimized for repeatable performance. A nominal speed of 2000 rpm indicates the shaft velocity the unit can sustain under rated load conditions. The torque constant of 0.89 Nm/A links stator current to generated torque, simplifying current-loop tuning in the drive. When acceleration peaks occur, the winding can accept 37.0 A so that short bursts of energy are available for rapid starts. Mechanical output tops out at 30.7 Nm, providing a safety margin above continuous values. For static holding or emergency stops, the integrated brake develops 14.0 Nm of counter-torque, helping keep vertical loads from drifting.

Complementary characteristics support those dynamic figures. The brake circuit is energized by DC 24 ±10 % with a current draw of 0.75 A, allowing simple connection to 24-volt control supplies. Thermal losses are limited by a winding resistance of 1.40 Ω, while a 16 mH inductance smooths current transitions. Rotor inertia is 61 × 10⁻⁴ kg·m², offering a compromise between swift response and load stability. Assembly is centered by a 130 mm pilot diameter, and the keyed shaft is 32 mm in diameter with a 10 × 8 × 45 mm key for slip-free coupling. Feedback is provided through DSF digital encoder signals, and the power connector faces Side B to simplify routing in tight panels. Overall housing length is 312 mm, giving clear envelope data for installation planning.
