Product Description:

The SF-A5.0250.030-10.019 is a three-phase servo motor engineered by Bosch Rexroth Indramat within the SF Servo Motors series. It serves as a rotary actuator for CNC axes, pick-and-place gantries, and packaging lines, where it converts drive current into precise torque and speed for controlled motion. This allows machine elements to index, position, and repeat short cycles in automated production with stable response. Its role is to provide consistent rotary output in applications that depend on accurate motion control, repeatable cycle timing, and smooth speed changes.

At its rated operating point, the motor spins at 3000 rpm, which aligns with the commutation frequency supplied by the drive controller. Starting demands are handled by a locked-rotor torque of 23 Nm, while continuous stall conditions draw a standstill current of 16 A rms. The electromagnetic design delivers torque in proportion to current, as shown by a constant of 1.44 Nm/A. Heat developed in the stator is removed solely by natural convection, and the mounting flange is held to 190 mm to provide surface area for passive dissipation. Mechanical survivability includes 6 g of shock resistance, and two NTC sensors provide thermal protection by signaling overtemperature to the drive. The output shaft follows DIN 748 tolerances with a smooth profile for backlash-free coupling.

The bearing set is rated for 20,000 h of life at nominal load, and airborne sound pressure stays below 58 dB(A). Mounting compatibility is set by construction type IM B5, which provides a face-mount arrangement with a pilot register for centering. The shaft measures Ø32 × 58 mm and mates directly with clamped hubs or keyed bushings selected by the machine builder. No fan, brake, or additional sealing modules are included, which keeps inertia low and leaves position feedback to the external drive system.
