Product Description:

The SR-A1.0016.060-00.000 is a synchronous servo motor built by Bosch Rexroth Indramat and belongs to the SR Synchronous Servo Motors series. The unit supplies closed-loop rotary motion for positioning and speed control tasks in industrial automation, pairing with compatible inverters and feedback electronics to drive axes that need repeatable velocity profiles and quick acceleration. An integrated resolver supplies rotor position feedback to the drive controller, enabling high-bandwidth current loops and electronic commutation. Its compact frame suits packaging machines, pick-and-place gantries, and light material-handling stations. The electrical design provides constant torque over a wide speed range, while the housing can be coupled to gearboxes or direct loads.

A rated speed of 6000 rpm is the top continuous operating velocity before field weakening. Torque generation follows a constant of 0.67 Nm/A, so the drive can relate commanded phase current to motor output. During startup or blockage, the winding may draw 2.4 A and produce a locked-rotor torque of 1.6 Nm to overcome static friction. Dynamic response is influenced by a combined rotor and encoder inertia of 0.83 × 10⁻⁴ kg·m², which helps the motor accelerate quickly without excessive lag. Two embedded NTC temperature sensors report thermal status to protect the insulation system.

A square mounting flange of 70 mm sets the bolt pattern, and the overall body length is 196 mm, giving the motor a slim profile for tightly packed machine spaces. The steel shaft measures 11 × 23 mm and uses a keyway with a feather key to transmit torque without slip. Resolver feedback is interpreted by the drive at 8192 incr./rev., with a baseline accuracy of ±10 angular minutes for position monitoring. At 2.1 kg including the encoder, the motor keeps moving mass low on linear tables.
