Product Description:

The SF-A3.0093.030-10.037 servo motor is produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. It converts controlled DC-bus energy from a drive into regulated rotary motion for industrial axes that require synchronized position and speed control. An integrated absolute encoder returns real-time shaft angle data to the machine controller, enabling coordinated motion sequences in packaging lines, pick-and-place gantries, and small machining centers. This arrangement supports repeatable motion in applications where acceleration changes frequently and axis coordination must remain stable throughout each cycle.

At its nominal operating point, the rotor turns at 3000 rpm, a speed chosen to keep mechanical resonance above typical process frequencies. A torque constant of 1.35 Nm/A links stator current to output torque, which helps the drive respond predictably to command changes. During startup or stall, the motor can deliver 8.1 Nm while drawing 6.0 A RMS, figures that indicate short-term torque capability and inverter current demand. The power interface is supplied from a shared DC link held at 670 V, so the unit can operate on high-power multi-axis drives without individual rectifiers. Two NTC sensors embedded in the windings transmit temperature data for real-time thermal protection. That temperature signal helps the drive reduce overload before winding heat rises too far during repeated acceleration or low-speed holding.

The motor permits an allowable axial load of 133 N, which supports moderate thrust from belts or helical couplings without requiring extra bearings. The housing uses a 116 mm square flange and a 110 mm pilot diameter for centered mounting on standard gearboxes. The onboard encoder supplies 8 million incr/rev of digital feedback with a basic accuracy of 20 angular seconds, enabling sub-arc-minute positioning after power cycles without a homing routine. This feedback supports repeatable positioning across the full speed range, and the load rating is suitable for medium-inertia couplings and belt-driven axes.
