Product Description:

The SF-A4.0230.030-10.050 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. Designed to drive precision axes in automated machinery, it converts electrical energy from a matched drive into tightly regulated mechanical rotation. Positioning, speed, and torque loops in packaging lines, pick-and-place stations, or gantry systems use this motor to obtain repeatable motion under changing loads.

The motor operates from a direct DC bus of 670 V, which matches the output of Rexroth servo drives operating on 400 VAC mains. When the shaft is held stationary, the windings can draw up to 14 A and produce a stall torque of 22 Nm; these locked-rotor values indicate the startup demand that the amplifier and cabling must accommodate. During continuous operation, the motor reaches a rated speed of 3000 rpm, providing smooth motion across standard production cycles. Torque rises linearly with current thanks to a constant of 1.57 Nm/A, which supports current-based control. Operation is permitted at ambient temperatures up to 40 °C, and the rotor can withstand axial forces of 154 N without compromising bearing life. The mounting interface follows the IM B5 flange pattern for quick alignment on gearboxes or machine frames.

The mechanical envelope uses a flange diameter of 142 mm and a shaft measuring 24 × 50 mm, allowing direct coupling to standard hubs while maintaining concentricity. An ingress rating of IP67 shields the stator against dust and temporary immersion, helping protect lubrication and insulation. Dynamic response benefits from a rotor inertia of 0.0054 kg·m², enabling fast acceleration while preserving stability in position loops. Noise emissions are held to 58 dB(A), and the housing withstands shocks up to 6 g generated by rapid axis reversals. The motor has a minimum service life of 20000 h under normal operating conditions.
