Product Description:

The SR-A0.0008.060-10.000 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. It is intended for tightly regulated rotary positioning tasks within automated assembly stations and high-speed handling systems. Operating from a regulated DC bus, the motor converts electrical power into precisely metered mechanical rotation that drives lightweight tooling or miniature gearboxes along a programmed motion profile. Its sealed construction supports installation on moving axes exposed to lubricants, airborne particles, and frequent motion in confined machine spaces.

The motor runs with a DC link of 670 V, allowing the connected drive to inject current without exceeding insulation limits. Under nominal excitation, it reaches a rated speed of 6000 rpm, making it suitable for fast indexing duties and rapid cycle changes. Torque production follows a constant of 0.67 Nm/A, so controller current commands translate into predictable mechanical output. The housing carries a sealing level of IP67, which blocks dust ingress and permits temporary immersion during washdown procedures. Position information is captured by a resolver with 8192 incr./rev., enabling fine interpolation when tight positional tolerance is required. Two integrated NTC sensors report winding temperature so the drive can respond before thermal overload develops.

A square flange of 55 mm provides the standard mounting interface, and the total inertial load equals 0.15 × 10⁻⁴ kg·m², supporting rapid acceleration without placing unnecessary demand on the drive. Overall mass stays at 1.3 kg, which helps limit moving-axis load in compact automation systems. Power is transmitted through a Ø9 × 20 mm smooth shaft that minimizes backlash in friction-fit couplings. If a brake is included, the overall length extends beyond the stated 156 mm footprint. At zero speed, a locked-rotor current of 1.2 A can hold 0.8 Nm of torque for clamping motions.
