Product Description:

The SR-A0.0002.060-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. This compact unit is intended for position and velocity control tasks in industrial automation, where precise electronic commutation allows tight coupling to servo drives. It uses a resolver for rotor feedback, and the keyed shaft transfers torque directly to gearheads or pulleys without a separate shaft adapter.

The motor maintains a rated speed of 6000 rpm, enabling fast cycle times in pick-and-place axes. A 55 mm square flange follows IEC sizing, so it mounts directly on compatible machines without adapter plates. Position feedback is delivered by a resolver that yields 8192 increments per revolution, giving high interpolation accuracy when matched to a digital drive; resolver tracking precision is within ±10 arcmin, which limits positional error at low speeds. This supports fine position correction during short indexing moves. Its housing carries an IP67 ingress rating, which seals the stator windings against dust and temporary water immersion. Electromechanical conversion efficiency is indicated by a torque constant of 0.44 Nm/A, so moderate current produces useful stall torque for small conveyors and clamps.

The dynamic response of the rotor is aided by a rotor inertia of 0.06 × 10⁻⁴ kg·m², letting the drive accelerate or decelerate the load with minimal lag. When the shaft is blocked, the motor can resist up to 0.2 Nm while drawing 0.45 A, figures that help set servo amplifier current limits. Total mass is 1.0 kg, which reduces load on linear slides and allows overhead mounting. An IM B5 end-shield mounting face supports direct flange installation, and the keyed output shaft measures 9 × 20 mm so couplings can be fitted without machining. The overall length is 126 mm, so the motor fits into compact machine spaces or narrow mechanical frames where axial clearance is limited.
