Product Description:

The SR-A0.0002.060-14.000 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. It is intended for precision positioning and velocity control in automated machinery where limited installation space and fast dynamic response are critical. By integrating resolver feedback and a holding brake, the unit provides closed-loop rotary motion and can be directly coupled to gear stages, ball screws, or timing pulleys in light-duty axes.

The motor can reach a rated speed of 6000 rpm, allowing high cycle rates in pick-and-place systems or indexing tables. Its electromagnetic design provides a torque constant of 0.44 Nm/A, so the drive requires only moderate current to generate working torque. A static holding torque of 1.0 Nm maintains the load position when motion is stopped, while the compact 55 mm square flange matches IEC size-55 gearboxes and mounting patterns. Rotor position feedback has a resolution of 8192 increments per revolution, giving the controller fine angular granularity for smooth interpolation and low tracking error. The total rotor inertia with the encoder is 0.06 × 10⁻⁴ kg·m², which supports fast acceleration without overshooting lightweight mechanical loads. This low inertia is useful for applications that require frequent direction changes and short movement cycles.

The integrated brake has a delay time of 30 ms to achieve full clamping after power is removed and a release time of 20 ms for quick disengagement during startup. At only 1.18 kg, the assembly adds minimal mass to moving gantries or rotary stages, yet it withstands stall events with a locked-rotor torque of 0.2 Nm. The brake draws a rated current of 0.5 A and has an inertia of 0.068 × 10⁻⁴ kg·m², minimizing the additional electrical and mechanical load while retaining the shaft. The motor measures 160 mm long with the brake installed, and its 9 mm diameter by 20 mm keyed shaft supports direct mechanical coupling without an adapter.
