Product Description:

The SR-A2.0013.060-10.000 belongs to the SR Synchronous Servo Motors series from Bosch Rexroth Indramat. This brushless AC servo motor is sized for mid-frame applications in packaging lines and small assembly gantries. By pairing its electromagnetic stator with integrated resolver feedback, the motor supports closed-loop torque and speed control so the drive can regulate position, velocity, or force as required by the automation sequence. It is suited to feed axes, transfer units, and indexing mechanisms that need repeatable motion over frequent production cycles.

The drive system uses a DC bus rated at 670 V, allowing high-voltage pulses that reduce current ripple at elevated speeds. Rotor position is monitored with a resolver that offers a feedback resolution of 8192 increments per revolution and a precision of ±10 angular minutes, giving the controller fine incremental data for velocity and commutation loops. The motor has a torque constant of 0.76 Nm/A, so each ampere of phase current produces a predictable increase in torque. Its flange measures 100 mm, supporting direct IEC-compatible mounting, and the total rotating inertia including the encoder is limited to 2 × 10⁻⁴ kgm² for quick response during acceleration and direction changes. The combination of compact mounting and low rotating inertia helps the axis respond quickly to commanded speed changes. This arrangement also supports smooth speed regulation at high motor speed.

When the shaft is held motionless, the winding draws a locked-rotor current of 1.7 A to generate a stall torque of 1.3 Nm, indicating the available holding capability before motion begins. Once released, the rotor reaches a rated speed of 6000 rpm, matching fast duty cycles in indexing tables and other high-cycle axes. A shaft measuring 14 mm by 30 mm transmits power to couplings on compact machine axes. Resolver feedback remains active across the full speed range to maintain phase alignment without external sensors.
