Product Description:

The SR-A2.0013.030-04.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SR Synchronous Servo Motors series. It operates as a compact rotary actuator intended for integration with Indramat digital drives, where it delivers precise velocity and position control for automated pick-and-place stations, indexing tables, and small axis modules. By combining permanent-magnet excitation with resolver feedback, the motor supplies closed-loop torque that supports rapid cycle times while maintaining consistent accuracy during continuous industrial duty.

At its rated shaft speed of 3000 rpm, the motor produces torque in proportion to phase current with a constant of 1.5 Nm/A, allowing the drive to calculate current commands for speed regulation. The holding brake is energized from a control bus of 24 VDC and draws 0.56 A. Once activated, it secures the axis with 3.2 Nm of static torque to help prevent load drift during power-off states. Dynamic response is supported by the low rotor inertia of 0.0002 kgm², which reduces acceleration lag and helps the axis follow high-frequency command profiles. For startup diagnostics, a locked-rotor current of 0.9 A corresponds to a stall torque of 1.3 Nm, providing reference values for overload detection.

The motor is intended for use with drive systems that operate from a DC bus up to 670 VDC, providing the voltage headroom required for the application. To withstand coolant spray, the housing is rated IP67 except at the shaft, so sealing at the shaft location must be handled by the installation. Position data comes from the integrated resolver, which has a mechanical accuracy of ±10 angular min and an interpolated resolution of 8192 counts per revolution for fine single-turn feedback. Mechanically, the flange face measures 100 mm in diameter and supports a Ø14 × 30 mm keyed shaft, providing a standard interface for couplings and gearheads.
