Product Description:
Bosch Rexroth Indramat manufactures the SF-A3.0068.060-00.000 servo motor as part of the SF Servo Motors series. In an automation cell, this unit converts drive current into controlled rotary motion so actuators, indexing tables, or compact spindles can follow commanded profiles. The motor is prepared for single-turn absolute feedback, allowing the drive controller to know the shaft position immediately after power-up without a homing move. This feedback arrangement helps the axis resume operation quickly after a restart and supports accurate positioning in repeatable motion sequences.
A flange diameter of 116 mm conforms to the IM B5 face-mount format, so the housing seats against a machined surface rather than using foot bolts. At a rated speed of 6000 rpm, the rotor can support rapid index cycles in pick-and-place or light spindle duties. If the shaft is blocked, the motor can withstand a locked-rotor torque of 6.8 Nm while drawing 9.4 Arms from the inverter. During normal running, the electromagnetic design produces torque in proportion to current with a constant of 0.77 Nm/A, giving the controller a linear relationship for closed-loop tuning. The mounting face, internal bearings, and 255 mm overall length without a brake help keep the rotor aligned and limit overhang loads during coupled operation.
Dynamic response is influenced by a reflected inertia of 11.3 ×10⁻⁴ kg·m², letting the axis accelerate without overshooting when paired with small gear ratios. With a mass of 10.2 kg, the stator adds minimal weight to gantry axes while still providing enough thermal mass for duty cycles protected by two internal NTC sensors. Those sensors allow the connected drive to monitor winding temperature and respond before overheating develops during repeated acceleration. The keyed output features a shaft sized Ø19 × 40 mm, giving space for standard couplings and pulleys. Sealed connectors and gaskets achieve IP67, so the motor resists dust ingress and temporary water immersion when the harness is mated.
