Product Description:

The SR-A1.0008.060-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. This compact unit is intended for closed-loop positioning and velocity control in assembly lines, handling modules, and packaging axes. When connected to a compatible Rexroth drive, the motor delivers accurate mechanical output while reporting the shaft angle to the controller. This feedback allows the drive to correct motion continuously and maintain precise control during changing load conditions.

The resolver supplies 8192 increments per revolution of interpolated resolution and maintains an accuracy of ±10 arcminutes across the full speed range. The stator has a torque constant of 0.6 Nm/A, which establishes the proportional relationship between phase current and developed torque and allows the drive to calculate load response from current. Under rated conditions, the rotor can spin at 6000 rpm, making the motor suitable for light pick-and-place heads and other fast-moving mechanisms. Mechanical coupling is supported by a 70 mm square mounting flange, while the smooth shaft measures 11 mm in diameter and extends 23 mm. This shaft profile works with backlash-free clamping couplings and helps reduce fretting at the connection. The rotor inertia is 0.43 × 10^-4 kg·m², which supports rapid acceleration when the motor is paired with low-mass loads.

When the axis is commanded to hold, the motor can sustain a locked-rotor torque of 0.8 Nm while drawing 1.35 A, providing holding force for fine-tolerance tools. The housing has an overall length of 156 mm without a holding brake, allowing the motor to fit within shallow machine frames. Its mass of 1.4 kg limits the additional moving weight on gantry or delta robot arms. A mating connector is not included, so a compatible plug set must be selected for the molded stator receptacle. The smooth, unkeyed shaft allows a hub-style clamp to center accurately around its diameter without relying on a keyway for alignment.
