Product Description:
The SR-A5.0700.030-00.060 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. As a rotary actuator, it converts drive current from a matched inverter into controlled torque and speed for indexing tables, packaging axes, or gantry drives where high positional repeatability is required in industrial automation environments. It is supplied as a framed unit with flange mounting, a keyed shaft, and integrated resolver feedback, allowing direct coupling to machinery and closed-loop drives.
Its nominal operating point is a speed of 3000 rpm, which the drive maintains as long as the phase current remains within the thermal limit. The electromagnetic design provides a torque constant of 1.53 Nm/A, so each ampere of stator current produces a predictable amount of output torque. During startup, the motor can withstand a locked-rotor torque of 69 Nm while drawing up to 45 A. These limits assist with the selection of fuses, cables, and mechanical couplings. Position data for the control loop is generated by an internal resolver that provides 8192 increments per revolution with an accuracy of ±10 angular minutes, allowing fine position measurement without an optical encoder.
The motor is sized for installation in medium-frame machinery. A rotor inertia of 257 × 10⁻⁴ kg·m² balances quick acceleration with velocity stability, and the assembled motor weighs 50 kg. Mounting is provided through a circular flange with a diameter of 180 mm and a mounting width of 190 mm. The mounting interface is compatible with standard IEC patterns and includes a center hole threaded to DIN 332-DS M12 for drawbar extraction. Power is transmitted through a keyed shaft measuring 32 mm in diameter and 58 mm in length. The supplied A10×8×50 feather key secures attached hubs against slipping, while the keyed shaft supports repeatable coupling alignment. The motor has an overall length of 483 mm, which should be considered when determining the required installation clearance behind the mounting surface.
