Product Description:

The SF-A3.0042.030-10.037 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. As an electromechanical actuator, the unit converts drive current into controlled rotation for positioning, feed, or speed-regulated axes in automated equipment, where stable torque delivery supports repeatable motion during indexing, transfer, and synchronized machine cycles. Its mechanical interface uses a B5 flange arrangement for direct mounting to gearboxes or machine frames, and the sealed housing supports use in washdown or particulate environments common to manufacturing lines.

The motor’s continuous operation envelope is centered on a rated speed of 3000 rpm, giving the drive a predictable velocity reference for most duty cycles. When power is first applied and the rotor is locked, a locked-rotor current of 2.3 A is drawn during startup or stall conditions, and this value helps set fuse sizing and drive current limits. A torque constant of 1.6 Nm/A means each ampere of phase current produces 1.6 newton-meters of torque, which helps the amplifier deliver predictable shaft output. A protection rating of IP67 confirms that the enclosure prevents dust ingress and withstands temporary immersion, reducing the need for external covers in damp or dusty areas. Dynamic response is influenced by a rotor inertia of 7 × 10⁻⁴ kg·m², which supports rapid acceleration without excessive drive power when quick starts and stops are required.

The assembly tolerates production floor impacts up to 6 g, so unexpected shocks during installation, handling, or pallet transfer are less likely to affect alignment. Two integrated temperature probes provide thermal supervision, and this twin-sensor arrangement is listed as 2 NTCs so the controller can derate or shut down before winding insulation is stressed by overheating. The motor is intended for closed-loop servo applications that require sealed construction and moderate rotor inertia on packaging, transfer, and feed axes.
