Product Description:

The SF-A3.0068.030-10.053 is a servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. Designed for closed-loop motion control, it converts electrical energy into accurately regulated rotary output used in indexing tables, pick-and-place axes, and packaging spindles. Integrated position feedback and temperature monitoring give the drive controller the data needed to command speed, hold position, and protect the windings during operation. That controlled output is useful on axes that must start, stop, and reverse without drifting from the commanded path. The motor is also suited to applications that require repeatable acceleration and stable motion under changing load conditions.

Mechanical interfacing follows the IM B5 construction type, so the housing bolts directly to a machine wall through its face flange while the shaft remains centered by the pilot. The flange diameter is 116 mm, which supports direct mounting where the surrounding machine uses the same centering fit and bolt pattern. This face-mount arrangement helps keep the motor aligned with the driven load and supports compact machine layouts. The connected drive supplies a DC link of 670 V, and the motor is rated for continuous operation at 3000 rpm. Its torque constant is 1.36 Nm/A, so the controller can relate phase current to produced torque with predictable response. An absolute encoder supplies single-turn position data, and two NTC sensors in the windings report thermal conditions to the drive.

When the rotor is prevented from turning, the motor draws a locked-rotor current of 5.0 A and can withstand a stalled torque of 6.8 Nm without mechanical damage. Such loading can occur during brief holding periods, indexing pauses, or temporary obstruction at the driven axis. Under normal load, acoustic emission remains below 58 dB(A) max, which helps limit operating noise around the machine. The assembly tolerates shocks up to 6 g, allowing use on mobile gantries and other installations that experience intermittent impact or abrupt directional changes.
