Product Description:

The SF-A2.0041.030-00.031 servo motor is manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It functions as an electromechanical actuator for closed-loop positioning or velocity control in industrial automation systems such as pick-and-place modules, presses, and packaging axes. The motor converts controlled electrical input from a drive into precise rotary motion, allowing compact, flange-mounted integration in automated equipment.

At the electrical interface, the windings are designed for a DC link of 670 VDC; this bus voltage supports fast current rise times and limits cable size for long runs between the drive and motor. Under continuous duty, the rotor turns at a rated speed of 3000 rpm, balancing torque output and thermal load. The electromagnetic design provides a torque constant of 1.43 Nm/A, so each ampere from the drive produces predictable mechanical torque and simplifies current-mode control. A rotor moment of inertia of 6×10⁻⁴ kg·m² enables rapid acceleration while keeping overshoot manageable. Mechanically, the unit bolts to a machine frame through a DIN B5 mounting flange that measures 100 mm, ensuring compatibility with common gearboxes.

The motor body length without a brake is 233 mm, and the housing mass is 7.1 kg, allowing overhead or gantry installation without excessive structural reinforcement. During startup, the stator can draw a locked-rotor current of 2.8 A to generate a standstill torque of 4.0 Nm; this capability permits static holding of moderate loads until velocity feedback is established. The assembly withstands mechanical shocks up to 6 g, supporting mobile equipment or environments with intermittent impact. A keyed Ø14 × 30 mm shaft transmits power while preventing slip, and the keyway with feather key simplifies coupling alignment. Classified as construction type IM B5, the mounting face carries both radial and tangential loads without additional feet.
