Product Description:
The SF-A2.0041.030-00.050 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. As a closed-loop drive element, it converts commanded current into controlled shaft torque and speed, enabling precise positioning, contouring, and velocity regulation in automated machinery and robotic axes. It is intended for line-fed inverter systems that require stable performance during frequent start-stop cycles. Its synchronous design supports repeatable motion in equipment where accurate speed changes and position correction are required throughout normal operation.
At a rated speed of 3000 rpm, the motor reaches its nominal operating point when the inverter supplies a DC link of 670 V. The torque constant is 1.43 Nm/A, which gives a linear relationship between phase current and generated torque, so each ampere delivered by the drive contributes predictable mechanical output. During startup, the unit can draw a locked-rotor current of 2.8 A to develop a stall torque of 4.0 Nm, values that describe its ability to overcome static friction. An admissible axial force of 70 N allows moderate thrust loads to be transmitted through the shaft without reducing bearing life. Natural convection removes heat from the housing, the integrated absolute encoder feeds position data back to the controller without homing, and two NTC temperature sensors monitor winding heat while the keyed shaft with a feather key provides positive mechanical coupling.
In IM B5 construction form, the motor uses flange mounting and leaves the shaft free for direct coupling to the driven mechanism. This mounting style supports accurate face alignment on machine plates and similar interfaces. The motor withstands shocks up to 6 g, which helps it remain suitable for machines subject to rapid indexing or transport impacts. Acoustic emission is limited to 58 dB(A), supporting installation near operators without additional acoustic dampers. Lower audible output can also be useful in enclosed work areas.
