Product Description:

The SR-A3.0093.060-10.000 is a synchronous servo motor built by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. Designed for machinery that requires fast, repeatable positioning, the unit converts electrical energy into controlled rotary motion for indexing tables, packaging stations, and pick-and-place axes. Its electromagnetic construction works with compatible servo drives to close velocity and position loops under demanding cycle times. Because the rotor responds quickly to command changes, the motor can support synchronized moves in packaging and handling systems where cycle consistency matters.

It delivers a rated speed of 6000 rpm, enabling high throughput while staying within thermal limits for continuous duty. A torque constant of 0.67 Nm/A relates phase current to mechanical output, allowing the controller to predict torque production accurately. During startup or when the shaft is blocked, the windings can accept 13.5 A and develop a locked-rotor torque of 9.1 Nm, giving the axis enough breakaway force for static loads. The housing carries a sealing grade of IP67 except at the output flange, so dust and coolant are kept away when connectors are fitted correctly. Two NTC temperature sensors embedded in the stator report winding temperature to the drive, allowing overload protection and derating functions during heavy operation.

The motor uses an IM B5 face mount that matches a flange diameter of 116 mm for direct attachment to the machine frame. Its keyed output shaft measures Ø19 × 40 mm, supporting direct coupling without intermediate hubs. The keyed shaft also helps maintain positive torque transfer in belt drives or rigid couplings. Total motor mass is 12 kg, and the housing length reaches 287 mm, which helps with installation layout and moving-axis load calculations. Dynamic response during acceleration is influenced by a rotor inertia of 16 × 10⁻⁴ kg·m², enabling rapid speed changes while supporting stable servo tuning. Position feedback is provided by a resolver with a resolution of ±10 angular minutes and 8192 increments per revolution, which supports accurate interpolation for precise moves.
