Product Description:
The SF-A5.0250.030-04.050 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. This motor is intended for closed-loop position and speed control in automated machinery such as pick-and-place axes, tool spindles, and gantry drives. By combining a permanent-magnet rotor, an integrated brake, and high-resolution feedback, it delivers rapid response and precise holding capability for repeatable motion sequences in industrial automation.
The housing is prepared for IM B5 mounting and seats on a 190 mm flange, letting the motor bolt directly to standard machine plates. A keyed shaft is provided for positive torque transfer, while the brake circuit draws 1.33 A from a 24 VDC ±10% supply with 5% ripple to energize its holding brake. Under power-off conditions, that brake delivers 56 Nm so vertical or suspended loads stay in place. Motion feedback is supplied by an absolute encoder with a resolution of 8,000,000 Incr/Rev, and the system’s ±20 arcsec accuracy supports fine positioning without external scales. During continuous operation, the rotor can spin at 3000 rpm, matching common mechanical transmission ratios in mid-power automation lines. Two NTC temperature sensors embedded in the stator enable drive-level thermal monitoring.
Dynamic performance begins with a rotor inertia of 83 ×10-4 kg·m², which provides a balance between acceleration capability and load stability. At a standstill, the electromagnetic package develops 25 Nm, and that torque is available with a standstill phase current of 16.1 A. Because the winding produces 1.44 Nm/A, the controller can relate mechanical output directly to current feedback. Mechanical coupling is handled through a shaft that measures Ø32 × 58 mm, giving sufficient engagement length for standard keyed hubs while minimizing overhung load on the motor bearings.
