Product Description:

The SF-A4.0125.030-10.010 is a motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for precision positioning and speed control tasks in automated assembly lines, packaging equipment, and handling systems where rapid and accurate torque delivery is required. Its compact frame and standardized flange support straightforward installation in automated equipment, and the motor works with compatible Indramat drive controllers for closed-loop motion. The brushless design also supports repeatable performance during rapid start-stop cycles and steady-speed operation.

At a rated mechanical speed of 3000 rpm, the brushless servomotor provides continuous motion for synchronous drive stages. When used with a matching drive, the DC link can reach 670 V, so the system can deliver higher power without excessive current. With a torque constant of 1.37 Nm/A, phase current is translated into predictable shaft torque for stable control response. A high-resolution absolute encoder outputs 8 million increments per revolution, enabling very fine position feedback during indexing and contouring moves. For startup or short overload events, the locked-rotor torque can peak at 14.5 Nm, which helps the axis overcome inertia at standstill. The unit also includes two NTC sensors for thermal monitoring, and its smooth shaft avoids keyway stress concentrations.

During blocked rotation, the locked-rotor current limit is 10.6 A, allowing the control system to respond quickly to a stall condition. Positional fidelity is supported by encoder accuracy of ±20 arcsec, which helps maintain repeatable alignment in applications that rely on precise referencing. Mechanically, the motor uses the base construction code IM B5, so it mounts with a flange and a free shaft end. That flange follows IEC 72-2 / DIN 42 948, matching common gearbox and coupling dimensions used in modular automation equipment. This arrangement supports compact installation where accurate shaft alignment and a rigid face-mounted connection are required.
