Product Description:

The SR-A1.0012.060-14.000 is a compact motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It converts drive current into rapid, precise rotation for positioning axes and small pick-and-place modules in automated lines. Designed for sealed machine zones, the unit integrates a mechanical shaft, electromagnetic windings, and a resolver feedback channel so the connected drive controller can close a speed and position loop without external encoders. Its compact format helps it fit machine layouts where space is limited and fast axis response is required.

The motor reaches a rated speed of 6000 rpm, allowing short cycle times in indexing tables and lightweight gantries. Each ampere delivered to the stator produces torque according to a constant of 0.64 Nm/A, so drive sizing can be matched to the load demand. The spring-applied brake operates on 24 VDC and provides a static holding capacity of 2.0 Nm, which helps prevent back-drive on vertical axes. The protection class is IP67, so the housing resists dust ingress and temporary water immersion in washdown or coolant-rich equipment. Locked-rotor current of 1.9 A and locked-rotor torque of 1.2 Nm describe stall behavior, while a brake rated current of 0.4 A helps determine supply sizing for the brake circuit.

Dynamic response is influenced by a rotor inertia of 0.63 × 10⁻⁴ kg·m², and this low value supports quick acceleration without excessive drive peak current. The solid shaft measures 11 mm in diameter and extends 23 mm, matching standard coupling hubs used on compact servo axes. Position information comes from a resolver with a resolution of 8192 increments per revolution, allowing fine motion interpolation even at high speed. The low rotating mass helps small-axis assemblies respond quickly during repeated start-stop motion while maintaining stable feedback performance.
