Product Description:

The SF-A5.0250.030-10.067 is a servo motor supplied by Bosch Rexroth Indramat within the SF Servo Motors series. It functions as the mechanical output stage of a drive system, converting regulated current from a matching controller into controlled rotary motion for conveyors, pick-and-place heads, or indexing tables. By pairing rare-earth magnets with high-accuracy feedback, the unit delivers repetitive positioning without incremental drift, making it suitable for automated packaging, material handling, and light machining cells where repeatable speed and torque are required. The feedback arrangement also lets the controller correct position and speed during closed-loop operation.

The motor mounts through an IM B5 flange whose face measures 190 mm, while the pilot fits a centering seat of Ø180 j6 to support coaxial alignment with the driven machine. This mounting arrangement helps keep the shaft centered during installation and reduces coupling misalignment. The winding produces a continuous torque constant of 1.44 Nm/A, so the drive can relate shaft torque to phase current during operation. Under locked-rotor conditions, the shaft develops 23 Nm, indicating starting capability against static loads. During rated operation, the rotor reaches 3000 rpm, a speed suited to common transmission ratios in servo gearboxes.

Closed-loop feedback is delivered by an optical encoder that records 8 million increments per revolution and maintains absolute position within ±20 arcseconds. This resolution supports fine speed regulation and small position corrections during repeated cycles. A 1.25-size circular connector carries power through a 4 x 4.0 mm² cable, and the selected construction type keeps the stator sealed against coolant or oil splash encountered in inline production modules. Starting current peaks at 16 A when the rotor is held, so the drive must accommodate the associated thermal surge, while winding thermistors relay real-time temperature to help protect the insulation system. The assembly withstands shocks up to 6 g, allowing installation on moving gantries or press feeders.
