Product Description:
The SR-A3.0093.060-14.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. As a closed-loop drive element, it converts commanded current from a digital drive into proportional mechanical torque for positioning and velocity control in automated axes. The motor supports rapid indexing in packaging systems, pick-and-place equipment, and machine tools that require responsive, regulated motion.
At a rated speed of 6000 rpm, the motor delivers continuous motion for high-throughput applications. The brake provides a continuous holding torque of 10.0 Nm to secure stationary loads when motor torque is unavailable. A torque constant of 0.67 Nm/A establishes the relationship between phase current and developed torque during servo regulation. The internal brake operates at 24 V and draws 0.66 A, limiting the load placed on the control power supply. During startup, the windings can accept 13.5 A of locked-rotor current and generate 9.1 Nm of torque, allowing the axis to overcome static friction before accelerating. The smooth shaft measures 19 mm in diameter and 40 mm in length, allowing direct connection to compatible gearboxes, pulleys, or clamping couplings. Rotor inertia is 16 × 10⁻⁴ kg·m², balancing responsive acceleration with stable speed control, while the 326 mm housing length supports installation in compact machine frames.
A 116 mm square flange provides a rigid mechanical interface for mounting the motor to linear stages and compatible adapters. The assembly weighs 11.6 kg, providing adequate thermal mass for continuous operation without making the unit excessively difficult to position during installation. The housing provides IP67 sealing except on the output side, protecting the stator body against dust and temporary water immersion while leaving the shaft exit accessible for coupling and alignment. Position feedback comes from a resolver with an equivalent resolution of 8192 increments per revolution, enabling the drive to interpolate motion precisely for smooth contouring at high speed.
