Product Description:
The SR-A5.0700.020-10.016 belongs to the SR Synchronous Servo Motors series manufactured by Bosch Rexroth Indramat. It is a rotary servo motor intended for closed-loop positioning and velocity tasks in automated machinery such as pick-and-place axes, presses, or packaging lines. By converting electrical energy from a matched drive into controlled mechanical rotation, the motor supplies precise motion and torque for repeatable industrial processes. Its application range suits equipment that requires stable speed control, accurate positioning response, and dependable operation over repeated motion cycles.
At a rated speed of 2000 rpm, the rotor delivers continuous shaft rotation suited to medium-speed indexing stations. During start-up, the motor can develop a locked-rotor torque of 69 Nm while drawing up to 34 A rms. These values indicate the standstill torque available at launch and the peak current the drive must support. The windings are energized from a DC link maintained at 670 V, enabling compact cabling and reduced conductor losses compared with lower-voltage designs. With a torque constant of 2.0 Nm/A, each ampere of stator current produces predictable shaft torque. Resolver feedback with 10 angular minutes of accuracy and an 8192 increment resolution supplies position data for the control loop without requiring an optical encoder, which helps the motor remain suitable for electrically noisy industrial settings.
Long operating life is supported by a bearing life of 20,000 hrs, which helps the motor remain suitable for continuous-duty installations. The aluminum rotor presents an inertia of 257 ×10⁻⁴ kg·m², giving the axis moderate dynamic response without excessive drive demand during acceleration and deceleration. When installed in an IM B5 flange mounting configuration, the motor generates a sound pressure level of 58 dB(A), which supports use in common production environments. The motor can withstand mechanical shocks up to 6 g, helping it tolerate abrupt motion changes and normal handling stresses.
