Product Description:

The SF-A3.0068.060-10.000 is a servo motor built by Bosch Rexroth Indramat and part of the SF Servo Motors series. It converts drive current into regulated rotary motion for positioning tables, feeders, and high-cycle packaging axes where fast speed changes and repeatable accuracy are important. The motor is intended for applications that need quick acceleration, consistent speed control, and accurate stop positions during repetitive cycles. Its overall motor length is 255 mm, so the assembly fits shallow machine frames where space is limited.

This motor reaches a rated velocity of 6000 rpm, allowing rapid indexing in high-speed motion systems. A torque constant of 0.77 Nm/A links commanded current to output torque, which helps the drive produce predictable torque response. Starting from rest, the rotor can deliver 6.6 Nm of locked-rotor torque while drawing 8.5 A, which is useful when the axis must overcome load at standstill. The rotor inertia is 11 × 10⁻⁴ kg·m², which supports quick acceleration while still helping smooth minor load variation. Axial loads up to 133 N can be applied through the shaft without premature bearing wear. Feedback is supplied by a single-turn absolute encoder, giving one absolute position value per mechanical revolution.

A flange diameter of 116 mm matches common IEC mounting interfaces, and the housing mass of 9.0 kg adds useful thermal mass during intermittent overloads. The shaft measures Ø19 × 40 mm and uses a smooth shaft style that suits collet or clamp couplings where low backlash is preferred. The mating connector is not included, which allows cable selection to follow the installation layout and the required connection standard. These dimensions help the motor fit mid-frame gearheads or belt pulleys while maintaining a compact installation footprint.
