Product Description:

The SF-A3.0093.060-14.050 is a servo motor from the SF Servo Motors series manufactured by Bosch Rexroth Indramat for use in automated positioning axes and cyclic handling stations. It converts controlled drive current into rotary motion with tightly regulated speed and torque, allowing machine tools, pick-and-place units, and packaging lines to follow programmed motion profiles with repeatable accuracy. This operating profile suits equipment that requires rapid starts, controlled stops, and consistent point-to-point movement over repeated production cycles.

This motor reaches a rated speed of 6000 rpm, enabling fast cycle times in high-speed axis applications. A torque constant of 0.67 Nm/A links drive current to produced torque, while a locked-rotor torque of 9.1 Nm is available at a locked-rotor current of 13.5 A during start-up or abrupt stops. Position feedback is supplied by a multi-turn encoder that generates 8 million increments per revolution, giving the control system fine motion resolution. Mechanical interfaces include a 116 mm square flange, a Ø110 j6 centering collar for concentric mounting, a DIN 332-DS M6 center hole for draw-bolt fixtures, and a size 1, 6-pin connector for electrical power; the recommended motor cable uses four 2.5 mm² conductors.

During rapid deceleration, the drive can dump kinetic energy into an internal resistor that absorbs 293 Ws of energy and has a resistance of 3.3 Ω. Dynamic response is supported by rotor inertia of 16 × 10⁻⁴ kgm², which helps balance acceleration with stable motion control when command values change. Closed-loop accuracy is refined by an encoder precision of ±20 angular seconds, allowing the system to hold position within tight mechanical tolerances. The DIN-standard center hole and keyed shaft match common transmission components and support straightforward mechanical integration.
