Product Description:

The SF-A3.0093.030-14.015 belongs to the SF Servo Motors series manufactured by Bosch Rexroth Indramat. This three-phase synchronous unit is intended for industrial automation tasks that require repeatable angular positioning and smooth velocity control. When paired with a compatible drive controller, the motor converts command values from a PLC or motion controller into controlled shaft rotation for conveyors, pick-and-place arms, and coordinated gantry axes. Its operating behavior is suited to applications that need repeatable starts, stops, and direction changes without sacrificing smooth speed regulation. That makes it suitable for packaging, assembly, and transfer equipment that runs in repeated cycles.

The mechanical output can reach a rated speed of 3000 rpm, and the electromagnetic design produces a torque constant of 1.35 Nm/A for predictable current-to-torque conversion. During startup, the drive may draw a locked-rotor current of 6.0 A and deliver a corresponding blocked-shaft torque of 8.1 Nm, values that help size protective devices and acceleration ramps. The power section is supplied from a DC link that may stand at 670 VDC, while the integrated holding brake receives control power from a separate 24 VDC supply. Acoustic emission stays below 58 dB(A), and the motor also has a shock resistance rating of 6 g to help maintain internal alignment during sudden mechanical impacts.

Axial loading up to 133 N can be applied without shortening bearing life, and the brake releases with a rated coil current of 0.66 A. When engaged, the brake holds the shaft with 10.0 Nm of static torque, which helps keep a vertical or suspended axis from drifting after power is removed. Dynamic response is aided by a rotor inertia of 0.0016 kgm², allowing quick speed changes with limited overshoot and stable response during short indexing cycles. This combination suits machines that alternate between frequent positioning moves and controlled holding periods.
