Product Description:

The SF-A5.0250.030-14.050 is a servo motor from Bosch Rexroth Indramat in the SF Servo Motors series. It supplies closed-loop position and speed control for indexing tables, gantries, and similar automation axes by converting drive current into rotary motion. A laminated stator, permanent-magnet rotor, and an integral electromagnetic brake form the electromechanical core that links the drive controller to the load in assembly, handling, and packaging machinery.

The motor’s dynamic profile is anchored by a rated speed of 3000 rpm, giving a consistent top velocity for continuous duty cycles. A torque constant of 1.44 Nm/A links drive current to developed torque and supports correct power-stage matching. During startup, the machine must overcome a locked-rotor torque of 23 Nm, and this stall condition draws a maximum locked-rotor current of 16 A from the drive. Motion responsiveness benefits from a rotor inertia of 83 × 10⁻⁴ kg·m², while the 190 mm flange and 345 mm motor body length contribute to the overall installed mass and mounting envelope. The motor also permits an admissible axial force of 380 N, and the splined shaft section measures 32 × 58 mm for coupling to compatible drive elements.

For static holding, the electromagnetic brake delivers 56 Nm of torque at a control voltage of 24 VDC and draws only 1.33 A, which helps limit heat during long idle periods. The brake assembly adds a reflected inertia of 30 × 10⁻⁴ kg·m² while keeping the total motor mass at 29.2 kg, a value that matters when the housing is mounted or when axis load distribution is calculated. Shock resistance up to 6 g helps protect internal laminations and feedback devices during rapid deceleration or transport. These operating characteristics suit positioning applications that need dependable holding force, controlled acceleration, and stable mechanical support under repeated motion.
