Product Description:

The SF-A5.0460.030-00.053 is a servo motor built by Bosch Rexroth Indramat and supplied within the SF Servo Motors series. Designed for closed-loop positioning and velocity control in automated machinery, the unit converts drive current into rotary motion that can be precisely synchronized with feedback from its internal encoder. This makes the motor suitable for pick-and-place axes, packaging lines, or tooling stations where accurate torque delivery and repeatable speed regulation are required.

At the power stage, the motor is intended for a 670 V DC link, giving the inverter margin needed for fast current transients. An integrated absolute encoder reports rotor position immediately after power-up, eliminating the need for homing cycles. Under stalled conditions, the stator can deliver 46 Nm of locked-rotor torque while drawing a phase current linked to the torque constant of 1.58 Nm/A. When released, the shaft can reach a rated operating speed of 3000 rpm, and dynamic behavior is supported by a rotor inertia of 0.0166 kgm² that balances acceleration with stability. Two NTC thermal sensors embedded in the windings protect the insulation by signaling the drive when temperature thresholds are approached. The assembly withstands mechanical shocks up to 6 g, and its IM B5 construction provides a flange-mount interface compatible with standard housings.

Mechanical integration is simplified by a 190 mm square flange that centers the shaft and aligns with ISO pilot dimensions. During startup, the windings can tolerate a locked-rotor current of 29 A, which helps with fuse and cable sizing. Axial loads of up to 380 N may be applied without exceeding the bearing limits, enabling use with ball screws or helical couplings that introduce thrust. In continuous duty, the acoustic emission remains below 58 dB(A), contributing to quieter operation when multiple axes run at the same time.
