Product Description:

The SF-A4.0172.030-00.015 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. As a rotary actuator, it converts drive current into controlled torque and speed for positioning tasks in automated machinery and material-handling lines. In these systems, the motor supports accurate starts, stops, and speed changes during repeated production sequences. The motor interfaces directly with compatible drive controllers through its power and feedback connectors, supporting closed-loop axis control with stable motion response during repeated operating cycles.

The servo draws energy from a DC bus rated at 670 V, making it compatible with IndraDrive link supplies. Under nominal conditions, the rotor spins at 3000 rpm, a speed that matches common machine feed rates. Torque output scales with a constant of 1.38 Nm/A, giving predictable acceleration when current-controlled inverters modulate phase current. The mechanical interface uses a flange width of 142 mm, and a locked-rotor current of 13 A indicates the current drawn when the shaft is held. Position feedback exits through a 17-pin encoder socket, while power enters through a size 1, 6-pin connector. This layout keeps the feedback path separate from the power connection while preserving a compact motor package. Rotor inertia of 40 × 10⁻⁴ kg·m² supports dynamic response, two NTC temperature sensors monitor winding heat, and a keyed shaft with a feather key simplifies coupling to gearboxes or pulleys.

The motor can develop 18 Nm of locked-rotor torque, enough to resist transient loads until motion resumes. During supply interruptions, the drive applies plug braking, and the winding can absorb 785 Ws of energy before an external 1.0 ohm resistor dissipates additional heat. This helps the axis slow in a controlled way when power loss occurs. The housing is sealed to IP 67, so it withstands dust and brief immersion without auxiliary covers. Feedback cabling can extend to 100 m without repeaters, which adds flexibility when the drive is mounted farther from the axis in larger machine layouts.
