Product Description:

The SR-A1.0023.060-00.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for precision positioning and velocity control in automated handling systems, pick-and-place modules, and compact machine axes where rapid response and high cycle rates are required. The motor supports closed-loop rotary motion in equipment that depends on accurate starts, stops, and speed changes during repeated operating cycles.

The motor mounts to machinery through a 70 mm square flange that matches a Ø60 j5 pilot diameter for concentric alignment. A Ø11 × 23 mm stepped shaft delivers torque to the load, while the IM B5 mounting style locates the flange on the drive-end face for easy front installation. Threaded fastening is provided by a center hole prepared to DIN 332-DS M4, and the housing carries an IP67 protection rating so the unit resists dust ingress and temporary immersion during washdown. At startup, the locked-rotor condition draws 3.3 A to generate 2.3 Nm, values that help size the drive amplifier and mechanical couplings. During operation, the winding produces continuous torque in proportion to a 0.69 Nm/A torque constant, and the stator can spin to a rated 6000 rpm for high-speed cycles. Total rotating mass, including the feedback assembly, equals 1.20 × 10⁻⁴ kg·m², allowing fast acceleration without excessive drive current.

Position feedback is supplied by a Resolver that offers a resolution of 8192 incr./rev. and maintains an accuracy of ± 10 angular min, enabling fine commutation and tight velocity loops without optical encoders. The analog sine-cosine signals from the resolver combine with the low inertia to support rapid settling after index moves. The sealed feedback arrangement helps the motor remain suitable for operating areas where dust or moisture may be present.
