Product Description:

The SF-B4.0230.060-10.047 is a brushless servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. As a compact rotary actuator, it converts command currents from a drive into mechanical rotation for positioning tasks in automated machinery. Its brushless architecture minimizes maintenance, while an integrated absolute encoder supplies the control system with immediate position data for precise closed-loop operation in packaging lines, pick-and-place axes, and other cyclic motion stations. This arrangement also supports repeatable starts, stops, and reversals in machines that run frequent indexing sequences.

At its rated speed of 6000 rpm, the rotor delivers continuous motion that matches high-throughput machine cycles. The associated DC link of 670 VDC allows the connected servo drive to develop the voltage margin needed for rapid acceleration without saturating the windings. During start-up or a jam condition, the unit can draw a locked-rotor current of 25 A, producing a stall torque of 22 Nm; these values help size fuses and determine gear ratios for breakaway loads. A torque constant of 0.88 Nm/A links commanded current directly to output torque, helping the drive respond predictably to changing load demands.

The motor mounts to machinery through a 142 mm square flange, and its smooth shaft simplifies coupling when low backlash is important. Power is routed through a size 1.5, 8-pin connector that accepts a supply lead with a cross-section of 4 × 6.0 mm², which helps limit resistive losses at the stated current levels. Internal protection relies on 2 NTCs that track winding temperature, allowing the drive to intervene before insulation limits are reached. The assembly withstands shocks up to 6 g, so it can remain aligned in applications subject to rapid indexing or end-stop impacts. The absolute feedback remains available after power is restored, which helps the axis return to service without repeating a full reference move.
