Product Description:

The SF-A5.0460.030-00.050 is a three-phase servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. This model converts drive amplifier current into controlled mechanical rotation for indexing tables, pick-and-place axes, and other precise motion stages that require high dynamic response. Integrated feedback supports stable closed-loop operation, and the standard 190 mm square mounting flange helps the motor fit common machine layouts in this size class. Because it is intended for servo duty, the unit is suited to applications that need accurate starts, stops, reversals, and repeatable positioning.

Under continuous operation, the rotor reaches a rated speed of 3000 rpm, which suits many automated production cycles. Torque rises in proportion to current at 1.58 Nm/A, helping the drive maintain predictable response during acceleration and deceleration. During a stall event, the motor can withstand 29 A and deliver 46 Nm of locked-rotor torque long enough for protective logic to respond. Dynamic behavior is also influenced by a rotor inertia of 166 × 10⁻⁴ kg·m², which supports fast motion while limiting abrupt changes in the coupled load. The motor uses a 32 × 58 mm plain shaft and a DIN 332-DS M12 center hole for direct mechanical connection to pulleys or gearbox input elements.

Position data are returned through a sine-cosine encoder that offers 8 million increments per revolution and maintains an accuracy of ±20 arcseconds. This feedback format allows fine position correction and smooth speed regulation across a wide operating range, which is useful on axes that must settle quickly after short moves. Power conductors are routed through a molded cable with 4 × 10 mm² copper cores, and the cable adds only 0.67 kg/m to moving carriers. The relatively low cable mass helps reduce added drag on gantry axes and supports consistent motion where repeated flexing is expected.
