Product Description:

Bosch Rexroth Indramat manufactured the SF-A2.0041.030-10.057. The unit is part of the SF Servo Motors series and is intended for closed-loop positioning and speed control in packaging stations, assembly robots, and gantry axes. An absolute value encoder on the stator supplies high-resolution feedback to the drive controller, and passive cooling through radiation and natural convection keeps the housing temperature within allowable limits. By converting drive inverter commands into precise shaft movement, it delivers repeatable motion for indexing, sealing, and pick-and-place operations across industrial automation cells. The feedback system also helps the controller maintain position accuracy during rapid reversals and short indexing moves.

The unit reaches a rated velocity of 3000 rpm, giving the drive a clear ceiling for synchronous motion sequences. Its intermediate circuit tolerates up to 670 V DC, matching the high-energy busbars used in multi-axis cabinets. The available bus voltage supports operation in servo systems that use a shared DC supply across several axes. If the shaft is blocked, a locked-rotor current of 2.8 A develops a starting torque of 4.0 Nm, so couplings and connected mechanics must tolerate stall conditions. The motor can be coupled to gearboxes or frames through the standardized 100 mm flange, which supports direct installation on common machine interfaces.

The electromagnetic design yields 1.43 Nm/A of torque per phase ampere, allowing drive current limits to be translated directly into load capacity. Heat is removed by radiation and natural convection, and two NTC sensors embedded in the windings provide active thermal protection during extended duty. The NTC sensors allow the control system to react before winding temperatures rise too far. During routine operation, the motor emits 58 dB(A) of sound pressure, which helps keep noise moderate in production areas. It withstands transport and installation shocks up to 6 g, while the mounting orientation of IM B5 simplifies axial alignment on precision machinery.
