Product Description:

The SF-A2.0041.060-10.000 is a servo motor produced by Bosch Rexroth Indramat and assigned to the SF Servo Motors series. It is intended for closed-loop motion tasks in industrial automation where precise velocity regulation and position feedback are required. The motor couples directly to screw drives, belt stages, or gearboxes to translate controller commands into rotary movement for packaging, pick-and-place, and indexing axes. In this role, it supports repeated starts, stops, and reversals on machinery that depends on stable axis response throughout regular production cycles.

The motor reaches a continuous operating speed of 6000 min^-1, giving high peripheral velocity for fast-cycle equipment. A stall torque of 4.1 Nm is maintained at the locked-rotor condition while drawing a stall current of 2.7 A. This current-to-torque relationship indicates how much static load the drive can support at standstill. The electromagnetic design yields a torque constant of 1.43 Nm/A, so each ampere of phase current produces a predictable output torque. Dynamic behavior is supported by a rotor inertia of 5.4 × 10^-4 kg·m², allowing rapid acceleration without excessive drive demand. A Ø14 × 30 mm shaft transfers torque, and two NTC temperature sensors monitor winding heat for thermal protection during operation.

Mechanical integration is simplified by a 100 mm square flange that mates to gearheads or machine plates in the IM B5 mounting orientation. The frame length of 233 mm and a mass of 7.1 kg keep the assembly compact for tight machine layouts while still providing the thermal mass needed for continuous duty. Feedback is supplied by a single-turn STG encoder with an accuracy of ±20 arcsec, enabling fine positioning without external scales. This feedback arrangement helps the control system correct small position errors during commanded moves and steady holding periods.
