Product Description:

The synchronous servo motor SR-A2.0013.030-00.000 is manufactured by Bosch Rexroth Indramat and belongs to the SR Synchronous Servo Motors series. Designed for integrated motion modules and light-duty gantries, this motor delivers programmable rotary output that can be synchronized with other machine axes. Within an automation cell, it acts as the electromechanical interface between the drive amplifier and the mechanical load, converting controlled current into repeatable shaft movement for tasks that demand consistent speed and positioning accuracy. It is intended for applications that need repeatable motion without the larger footprint of a heavy industrial axis. The motor can be used in packaging, transfer, and small handling systems where synchronized rotation supports coordinated machine timing.

Rotor position is reported by a resolver, giving a native feedback resolution of 8192 incr./rev. and a static precision of ±10 angular minutes, which allows the drive to close position loops without external interpolation. The motor reaches a rated speed of 3000 rpm, and each ampere supplied produces torque through a constant of 1.5 Nm/A. The current drawn when the rotor is locked is 0.9 A, which helps limit thermal buildup during holding conditions and static checks. Because the feedback device is integrated into the motor, the axis can report shaft position directly to the drive without separate external sensing hardware. That arrangement helps maintain stable control at low speed as well as during directional changes.

The mounting interface uses a 100 mm square flange, and a Ø14 × 30 mm shaft transmits torque to couplings or gears. Total rotating inertia, including the resolver, is 2 × 10^-4 kgm2, which supports quick acceleration without excessive servo gain. When mechanically blocked, the motor can hold 1.3 Nm, while the bare frame weighs 4.0 kg and extends 186 mm from flange to rear cover. The shaft and flange arrangement supports direct coupling to compact gear units, timing pulleys, or other rotary transmission elements. Its compact length also helps the motor fit machine sections where space is restricted and moving masses must stay low.
