Product Description:

The SF-B4.0230.060-10.000 is a brushless servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. Designed for closed-loop motion axes in assembly cells, packaging stations, and handling robots, the unit converts electrical energy into controlled rotary motion that can be commanded by Indramat drive controllers. Its compact frame and sealed construction allow installation directly on machinery without additional transmission components. By integrating high-resolution feedback and a low-maintenance stator winding, the motor delivers repeatable torque and speed profiles that are essential for synchronized multi-axis platforms.

Electrical performance is anchored by a rated speed of 6000 rpm, letting the drive reach high production cycle rates before mechanical resonance limits are encountered. A torque constant of 0.88 Nm/A links phase current to output torque, simplifying current-loop tuning. In a locked-rotor condition, the windings can withstand a torque of 22 Nm while drawing up to 25 A. The connected drive’s DC link must supply 670 V, so upstream filters and fuses must be sized accordingly. A shaft with a Ø24 × 50 mm journal transfers torque to couplings, and the overall housing length of 341 mm allows the motor to fit inside compact axial arrangements.

Dynamic behavior is influenced by a reflected inertia of 0.0054 kg·m², which permits fast acceleration without demanding excessive drive current. Position feedback is generated by a single-turn absolute encoder that resolves 8 million increments per revolution with an accuracy of ±20 arcsec, enabling contouring tasks that require fine angular granularity. The motor end bell has a flange width of 142 mm for ISO-compliant mounting, and its sealing system has an IP67 rating so coolant splashes or airborne dust do not reach the internal laminations. A mass of 25 kg provides thermal buffering during prolonged duty cycles while still permitting manual installation with standard lifting fixtures.
