Product Description:

The SF-A2.0041.030-10.037 is a servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It serves as a rotary actuator in industrial automation, supplying precise velocity and torque for positioning tasks on packaging machines, pick-and-place axes, and assembly stations. The model follows the IM B5 construction code, so its housing carries a round flange for face mounting, and its single-turn encoder supplies real-time rotor feedback to the drive controller during closed-loop operation.

The motor reaches a rated speed of 3000 rpm, allowing direct coupling to moderate-speed transmission stages without over-gearing. A torque constant of 1.43 Nm/A links drive current to mechanical output, giving the controller predictable torque modulation across the motion profile during acceleration and steady-state movement. The windings operate from a DC link of 670 V, matching the voltage class of compatible servo inverters. The housing carries a protection rating of IP67, so the stator and encoder remain sealed against dust and temporary immersion. For high-resolution feedback, the optical encoder delivers 8 million increments per revolution and holds an accuracy window of ±20 angular seconds. Start-up conditions draw 2.8 A of locked-rotor current and produce 4.0 Nm of locked-rotor torque, which helps with protection selection and load matching.

A flange width of 100 mm establishes the bolt pattern for machine frames, while the stator assembly endures mechanical shocks up to 6 g during handling or rapid stops. During continuous duty, emitted sound pressure stays below 58 dB(A), supporting installation near operators without added acoustic shielding. Heat is removed only by natural convection, eliminating external fans and reducing maintenance points while preserving the sealed housing. This cooling method supports compact machine layouts where additional airflow hardware is not preferred.
