Product Description:

The SF-A2.0013.060-00.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. Intended for precision axes in packaging, pick-and-place, and light machining systems, it converts controlled current into repeatable angular motion. Heat is removed by radiation and natural convection, so no fans or liquid cooling circuits are required. Position feedback is delivered by a single-turn absolute encoder, which allows immediate position awareness after power is restored and removes the need for homing moves. Its design suits machinery that depends on rapid reversals, short positioning moves, and stable closed-loop response.

During normal operation, the rotor reaches a rated speed of 6000 rpm, allowing high cycle counts on short-stroke mechanisms. The associated drive uses a DC link of 670 V for rapid torque production. A torque constant of 0.76 Nm/A relates phase current to developed torque, which helps the drive produce predictable motion during acceleration and holding. When the shaft is locked, current may rise to 1.7 A and the motor can produce 1.3 Nm of stall torque. Two NTC temperature sensors embedded in the windings allow the drive to reduce current as thermal limits are approached, helping protect the insulation during repeated starts and low-speed dwell periods.

The motor uses a square flange measuring 100 mm, and it has a 14 × 30 mm keyed shaft for standard couplings. The keyed shaft provides positive torque transmission when connected to common hubs or pulleys. Overall housing length without a holding brake is 186 mm, which helps the unit fit in compact enclosures. Its mass of 4.0 kg reduces handling effort during installation. With the encoder attached, the composite rotor inertia is 2 × 10⁻⁴ kg·m², balancing quick acceleration with low overshoot during speed changes and supporting direct belt drives or low-ratio planetary gearboxes.
