Product Description:

The SF-A3.0093.030-14.053 servo motor is produced by Bosch Rexroth Indramat for the SF Servo Motors series. It provides closed-loop rotary motion for numerically controlled machines, pick-and-place modules, and other automated stations where precise speed and torque regulation are required. The motor integrates with digital drives to translate commanded current into proportional mechanical output, supporting compact axis designs with low routine maintenance.

The electromagnetic profile centers on a rated speed of 3000 rpm, delivered through a torque constant of 1.35 Nm/A. During a locked-rotor condition, the winding draws 6.0 A and produces a stall torque of 8.1 Nm, which are useful values for drive matching and overload monitoring. Rotor dynamics are influenced by a moment of inertia of 16 × 10^-4 kgm², giving moderate acceleration without excessive current spikes. Mechanical mounting uses a 116 mm square flange, a Ø110 j6 pilot, and an M6 center hole thread that accepts puller bolts for service removal. Power is transferred through a Ø19 × 40 mm shaft, allowing direct coupling or keyed hub attachment in modular machine frames.

The bearing system tolerates an axial load up to 133 N, while radial forces depend on the coupling arrangement used in the machine. An enclosure rating of IP67 helps prevent dust ingress and withstands temporary immersion, and the housing can withstand impacts up to 6 g during transport or installation. Position feedback is supplied by an absolute encoder with 8 million increments per revolution of resolution and ±20 angular sec precision, supporting very fine motion control when the motor is paired with suitable transmission components. The sealed housing and high-resolution feedback make the motor suitable for enclosed machine areas and high-cycle servo loops.
