Product Description:

The Bosch Rexroth Indramat SF-A2.0026.060-14.050 belongs to the SF Servo Motors series and serves as a compact rotary actuator for coordinated motion axes in automated assembly, packaging, and light machining equipment. Designed for closed-loop speed and position control, the unit converts drive current into precise shaft rotation while keeping overall mass low for installation in space-restricted machine frames. Its compact frame supports lightweight servo applications that need fast response without excessive inertia. Closed-loop operation also helps the connected drive correct speed and position deviations during changing load conditions.

Under continuous operation, the rotor reaches a rated speed of 6000 rpm, so the motor can drive small pulleys or lead screws without auxiliary gearing. Output torque changes predictably with current, with a torque constant of 0.78 Nm/A, which supports stable current-loop behavior in the associated drive controller. Because the rotor inertia is only 4 × 10⁻⁴ kg·m², acceleration times stay short, which benefits indexing and pick-and-place moves. The allowable axial force is 70 N, which helps protect the bearing set from thrust loads transmitted by couplings or belts. During startup or stall events, the motor can provide 2.7 Nm of locked-rotor torque while the drive supplies 3.5 A of locked-rotor current. A 95 mm pilot diameter supports accurate mechanical alignment with common IEC flange patterns.

An integral holding brake secures the shaft when power is removed. It applies 3.2 Nm of static torque while adding only 0.35 kg of mass and 0.4 × 10⁻⁴ kg·m² of inertia to the system. Brake energization requires 0.56 A from a 24 VDC supply that can vary by ±10% without affecting performance. Engagement delay is 19 ms, and the brake releases in 29 ms; electrical ripple is held to 5%, supporting repeatable clamping behavior during rapid start-stop duty cycles.
