Product Description:

The SF-A3.0093.060-10.011 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. Designed for closed-loop motion axes, the unit converts electrical energy into controlled rotary movement so actuators, gantries, and spindle drives can follow programmed profiles under CNC or PLC supervision. It interfaces with drive amplifiers through a plug-in power and feedback connector and mounts to machinery with a rigid end-bell flange, providing a compact rotary drive for automated equipment where repeatable positioning and speed regulation are required.

The motor is intended for a drive system with a DC link of 670 VDC, so the inverter power stage must tolerate that voltage while switching at high frequencies. The mounting interface is a 116 mm square flange built to the IEC 72-2 / DIN 42948 pattern, which simplifies alignment with gearboxes or couplings that share the same hole circle. When the shaft is held stationary, the motor can draw a locked-rotor current of 13.5 A and generate 9.1 Nm of stall torque; these startup figures help set protection values and support thermal modeling. The connector style is plug-in, and the overall structure follows the IM B5 face-mount arrangement, which allows flush installation against a machine plate.

The pilot register is 110 mm in diameter, centering the housing precisely and helping prevent shaft misalignment under process loads. Once accelerated, the rotor can sustain a top velocity of 6000 rpm; with a torque constant of 0.67 Nm/A, the drive regulator can estimate torque output directly from phase current for responsive closed-loop control during indexing and speed changes. Internal temperature monitoring relies on two NTC probes, allowing the controller to reduce current before insulation limits are reached. The assembly withstands shocks up to 6 g, which helps protect feedback components in presses, pick-and-place heads, and other high-dynamics machinery.
