Product Description:

The SR-A1.0023.060-14.000 is a compact synchronous servo motor from Bosch Rexroth Indramat in the SR Synchronous Servo Motors series. Designed for precise position and velocity control in automated machinery, it uses resolver feedback and an integrated holding brake to keep loads in place when the drive is disabled. The motor has a 70 mm mounting flange and an overall length of 280 mm, which makes it suitable for tightly spaced axes that require rapid indexing and consistent torque density. This layout suits packaging, handling, and light assembly equipment where repeatable acceleration and compact axis spacing are important.

In continuous operation, the shaft reaches 6000 rpm, giving the axis ample headroom for high-speed assembly tasks. A torque constant of 0.69 Nm/A links commanded current to mechanical output, allowing the controller to calculate torque directly. Dynamic motion benefits from a rotor inertia of 1.20 × 10⁻⁴ kg·m², which helps limit stored rotational energy and supports short settling times during repeated starts and stops. The motor weighs 2.81 kg, so it adds only a light load to linear stages, while a locked-rotor current of 3.3 A and shaft dimensions of 11 mm diameter with a 23 mm extension support couplings used on small gearboxes.

For static holding and emergency-stop duty, the integrated brake provides 2.0 Nm of torque. It is actuated by a coil supplied with 24 VDC and 0.4 A, and when power is removed the mechanism can withstand up to 2.3 Nm at standstill to match the locked-rotor torque. Motion feedback is delivered by a resolver with a resolution of 8192 increments/rev. and a precision of ±10 angular minutes, giving the drive suitable granularity for interpolated motion profiles. The compact housing can be installed in either vertical or horizontal orientations without creating unusual clearance demands.
