Product Description:
The SF-A3.0068.030-10.037 is a servo motor built by Bosch Rexroth Indramat within the SF Servo Motors series. It operates as a torque-controlled rotary actuator for industrial automation duties such as positioning, contouring, and speed regulation on packaging lines, pick-and-place modules, or machine tools. By converting drive current from a compatible inverter into precise shaft motion, the unit supplies position feedback to the controller through its onboard encoder and supports synchronized multi-axis operation. Because feedback is integrated into the motor, the drive can monitor rotor position continuously instead of relying on a separate external measuring device. This arrangement helps keep motion repeatable during cyclic production tasks and coordinated machine movements.
The motor’s rated speed reaches 3000 rpm, providing a practical velocity reference for setting traverse rates and matching common transmission ratios. Its electromagnetic torque constant of 1.36 Nm/A links shaft torque to phase current in a predictable way, which supports stable response from the paired drive. During a locked-rotor condition, the shaft can withstand 6.8 Nm while the winding draws 5.0 Arms, so the drive can react appropriately during stall conditions. High-resolution position data come from an absolute encoder with 8 million increments per revolution and an angular accuracy of ±20 arc-seconds, allowing precise indexing and contour motion without relying on coarse feedback. That feedback resolution is useful on axes that need smooth interpolation at low speed as well as accurate stopping at target positions.
An admissible axial load of 133 N helps protect the bearings when couplings or belt forces apply thrust along the shaft. The rotor’s moment of inertia is 11 × 10⁻⁴ kg·m², which supports responsive acceleration while maintaining stable speed behavior. Sound emission remains below 58 dB(A), helping limit noise in enclosed equipment spaces. The motor uses a smooth shaft for clamp-style couplings, and the absolute encoder allows restart without a homing cycle after power is restored. Its cable arrangement uses four 1.5 mm² conductors and a size 1 connector, which keeps the power connection straightforward. The combination of moderate inertia and low sound output suits equipment that starts and stops often during normal production.
