SF-A4.0125.030-10.070

The Bosch Rexroth Indramat SF-A4.0125.030-10.070 from the SF Servo Motors series combines precision and performance in a compact design. Featuring a frame size 4 and design suffix A, this permanently excited magnetic motor delivers a rated speed of 3000 rpm with exceptional positional accuracy thanks to its absolute encoder (STG/MTG) offering ±20 angular seconds/8 million incr./rev. precision. With a torque constant of 1.37 Nm/A, the SF-A4.0125.030-10.070 ensures smooth acceleration and precise torque control across a wide range of industrial automation tasks. Compact dimensions and an integrated control drive enable seamless integration into high-density machine layouts.

Reliability is engineered into every aspect of the SF-A4.0125.030-10.070. The motor’s locked rotor torque of 14.5 Nm and corresponding locked-rotor current of 10.6 A provide robust starting performance under heavy loads. A moment of inertia of 40·10^-4 kgm² (incl. encoder) maintains rotational stability, while the mass without holding brake of 16 kg and maximum length without holding brake of 277 mm keep overall system weight and envelope in check. This combination of torque, inertia, and compact mass ensures dependable, repeatable motion even in dynamic positioning applications.

Designed for demanding servo applications, the SF-A4.0125.030-10.070 features a basic version smooth shaft option, offering minimal runout for precise coupling to gearboxes or feedback devices. The integrated absolute encoder and encoder mounting flange simplify commissioning and eliminate the need for external feedback components. This servo motor is an ideal choice for CNC machinery, pick-and-place systems, and robotics where high precision, reliability, and compact form factor are paramount.
