Product Description:

The SF-A5.0250.030-00.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It converts drive current into accurately regulated rotary motion for pick-and-place stations, packaging lines, and similar automation axes. Electrical feedback and a flange interface let the unit connect directly to digital drives, giving the system a compact actuator for position and velocity control. The combination of closed-loop feedback and direct mounting supports repeatable starts, stops, and speed changes in automated motion systems.

At its rated speed of 3000 rpm, the motor delivers continuous motion while remaining within thermal limits. During startup or jam conditions, it can sustain a locked-rotor torque of 23 Nm and a locked-rotor current of 16 A, which helps match the motor to a suitable drive and protection hardware. Position feedback is provided by a single-turn absolute encoder that yields 8 million increments per revolution with a precision of ±20 angular seconds, enabling fine interpolation for contouring tasks. This feedback quality helps the controller maintain accurate motion during indexing, speed regulation, and small position corrections.

Mechanical integration follows the IM B5 construction code, giving a flange mount with a centering diameter of 180 mm (j6) for repeatable alignment. The keyed shaft measures 32 × 58 mm and is supplied with a feather key to transmit torque into gearboxes or pulleys. Overall motor length is 300 mm, and the assembly weighs 24 kg, which helps when balancing axis mass against acceleration demands. Combined rotor and encoder inertia is 83 × 10⁻⁴ kg·m², and the torque constant is 1.44 Nm/A for predictable current-to-torque response. The housing has an IP67 rating on every surface except the output side, which supports washdown installation while still permitting direct coupling at the shaft.
